ADSL is short for Asymmetric Digital Subscriber Line. It is an advanced technology delivering high speed Internet access over standard telephone lines.
Compared to traditional analog or ISDN modems, ADSL transfers information 200 times faster subject to local loop length and quality.
The "A" in Asymmetric refers to different Downstream (from Central Office to subscriber) and Upstream (from subscriber to CO) speeds.

On-line Help
This on-line Help is intended to assist you in setting-up your Speed Touch. Additionally, valuable information can be found in:
the Help facility of the Command Line Interface
the Speed Touch User Manual, included in the box.
Configuring the Speed Touch
The WEB based management system allows you to configure most if not all of the Speed Touch’s features. The CLI goes one step further: it gives full control over all Speed Touch aspects.
The CLI is accessible via the serial interface (Pro only) or by opening a Telnet session to the Speed Touch (Home & Pro).
The Welcome page is the starting point for navigating to the various Speed Touch features. The buttons on this page are briefly described below.
Initial Setup : allows you to configure user defined IP parameters for your Speed Touch.
System Setup : via System Setup you can prevent unauthorized access to the Speed Touch configurations. In addition, it contains the Defaults button to restore factory defaults
Phonebook : this button will bring you to the Speed Touch Phonebook where Wide Area connectivity information can be added or changed.
Dial-in : via this button, Dial-Up connections can be established. Note these Dial-Up connections rely on PPP and IP routing which are supported in the Speed Touch Pro only.
Routing, Bridging and PPP-to-PPTP Relaying
The Speed Touch family supports multiple packet services. A packet service being defined as: the actions that need to be performed on each data packet in order to filter or forward packets to the next device in the communication chain .
Otherwise stated a packet service is a combination of processes transferring data packets from one side of the Speed Touch to the other side and vice versa. e.g. It will forward data packets from your PC'’s to remote destinations and vice versa. Yet all packet services will prevent communication between devices on your local network from escaping via the ADSL line.
Different packet services will be called upon depending on:
The port on which packets arrives e.g. LAN port or ADSL port;
The type of data packets, for example IP packets, MAC or PPP frames;
Their properties e.g. unicast, multicast;
The actual configuration of the Speed Touch.
The Speed Touch Home supports:
IEEE 802.1D Transparent Bridging
PPP-to-PPTP Relaying
The Speed Touch Pro supports:
IEEE 802.1D Transparent Bridging
PPP-to-PPTP Relaying
PPP & IP Routing with NAT/PAT (Network Address / Port Translation)
Classical IP & IP Routing with NAT
All packet services can be accessed via dedicated buttons:
Because IP Routing is not supported on the Home, pressing buttons PPP and CIP will have no effect.
In order to make local networking a plug & play experience, the Speed Touch supports automatic IP parameter configuration (DHCP client) or IP parameter distribution (DHCP server).
The Speed Touch exhibits a DNS server/DNS proxy. This functionality allows to use names instead of IP addresses in your local network.
Via this button, you can upgrade your Speed Touch with new software.
Pressing Save All, stores all settings to persistent memory.
Help
Shows this help information.
In this section you will find some generic principles applied throughout the Speed Touch WEB based management interface.
Besides the ADSL Banner, a generic Speed Touch page consist of three regions, called frames in WEB terminology:
the left-frame contains the buttons that will navigate you through all the pages of the WEB based management interface. This frame will always remain, independent of the function of the Speed Touch you want to configure.
the top-frame contains buttons like Apply, Help and Advanced to name a few. The buttons are almost generic for every page.
Note that there are no Save and Defaults buttons per page anymore. Use the Save all button in the left frame and the Defaults button in the System setup page instead.
The center-frame is the focus of the web based management. Pressing a button in the left frame will highlight a specific facet of the Speed Touch configuration. In this frame you can make changes to the exiting configuration.
Generic Procedure for WEB based management of the Speed Touch
Press a button in the left-frame e.g., Phonebook .
In the center-frame the Phonebook page appears .
You can now add new Phonebook entries or change existing ones.
Press Apply to activate the changes. (Note : the changes are stored in volatile memory only.)
Repeat the above procedure to configure other items of the Speed Touch.
Press Save all in the left frame if you wish to make your modifications permanent.
Pressing the Alcatel Logo in the upper left corner will bring you back to the Speed Touch Welcome page.
Press Initial Setup on the Welcome Page, to arrive at this page.
At the top, the unique MAC address of your Speed Touch will be shown. This MAC address can be used to identify your Speed Touch.
Note: MAC address is short for Medium Access Control address and is the standardized name for Ethernet address.
Although the Speed Touch comes with a default Private IP address, you can configure an IP address of your choice. This address will further referred to as user defined address. Just supply the IP address next to the IP Address field.
Next to Subnetmask you must supply either the default netmask for your IP address or, if subnetting is applied in your local LAN, the subnetmask. Below you can find the default netmasks for the various IP address classes.
|
IP Address Class |
Default Netmask |
Example (Private IP addresses) |
|
A (1.x.x.x .. 126.x.x.x) |
255.0.0.0 |
10.x.x.x |
|
B (128.0.x.x .. 191.255.x.x) |
255.255.0.0 |
172.16.x.x |
|
C (192.0.0.x .. 223.255.255.x) |
255.255.255.0 |
192.168.x.x |
The system Setup page allows you to protect your Speed Touch settings by configuring a system password. Just type it into the Password field. Note when supplying a password, asterixes will appear in the input field.
The next time you access a page, your browser will present you with a password window. Supply the password in the appropriate field to acquire full control over the Speed Touch again.
Note: a User Id is not required.
If you accidentally forgot your password, it can be cleared by DIP switches (Pro) or via a tiny push-button (Home) at the back of the Speed Touch. See the user manual for more information.
The red Defaults button on the second half of the page will set the device to factory defaults. It is similar in functionality as the above mentioned hardware reset method except that the IP settings remain to ensure continued connectivity to your browser.
This page shows the contents of the Phonebook and allows you to make changes or add new entries. The Speed Touch Phonebook is a repository for connectivity information. By default an amount of preconfigured entries already reside in the Phonebook.
What can the Phonebook do for you ?
It allows you to use named connections.
It provides an instant overview of all possible connections.
It indicates whether hardware and software resources are actually assigned to Phonebook entries.
It resolves conflicts when adding new connectivity information
How to use the Phonebook ?
The generic procedure is as follows:
Add entries to the Phonebook by supplying a Name, the virtual channel identifiers (VPI/VCI), and most importantly specify the Type of entry: Bridge, PPTP, PPP or CIP.
As you already noticed, Type refers to the different packet services that your Speed Touch model supports e.g. Bridge.
Then press Add and if no conflicts with other connectivity information exists, the entry is added to the Phonebook.
In the left pane press for example Bridge and the Bridging page appears.
Press the list box in the bottom row of the Bridge Port table. You will see a preselection of Phonebook entries. i.e. Only the names of Phonebook entries of which Type field matches “Bridge” are displayed.
Speed Touch Phonebook fields
Name
You can give any name to a new connection entry. Or your ISP or LAN administrator might ask you to use a mnemonic of their choice. In this way the entry refers to the remote organization. e.g., AlcatelHQ.
There are two limitations on names:
for Type PPTP, Name may not start with capital P or T (MS Windows restrictions).
if you want to use the PPP-to-DHCP spoofing feature of the Speed Touch, the name must start with DHCP. e.g. DHCP_Spoof1.
VPI & VCI
VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) are two parameters identifying ATM Virtual Channels. The Phonebook comes with a number of preconfigured VPI/VCI values.
It is the responsibility of the network operator to provide end-to-end connectivity throughout the network on these virtual channels. Due to regional differences or because of the specific policy of your local operator, other than the default VPI/VCI values may need to be used. In this case, your Network Operator, ISP or Corporate administrator will provide the correct values.
The VPIs can range from 0 to 15, and VCIs from 32 .. 511.
Note: if your Speed Touch is equipped with an ATMF25 interface, VPIs 0 to 7 are cross-connected between the ADSL port and the ATMF25 port. Unless these cross-connects are deleted via CLI, these VPI values (0.. 7) cannot be used.
Type
Refers to the Packet Service that is configured for an existing entry and you must select the type for a new entry. The Type entry is subsequently used to filter out those entries from the Phonebook when configuring an individual packet service.
Usage
Usage can be either Configured, or Free and is automatically filled out per connection.
As you will notice, next to a Free entry you will see a Delete action button. This implies you can delete the entry at will.
On the contrary, in case Usage is in the Configured state for a connection you are not able to delete this connection. This because the Speed Touch makes hardware and software resources reservations for these connections. Prior to deleting a Configured entry you have free its resources first.
Therefore:
Select the appropriate packet service;
Delete the entry;
Go back to the Phonebook;
You can now delete the Phonebook entry.
If Usage is in configured state for a particular connection, this implies that the connection is either in use or that parameters have been configured on another page. At maximum, 12 connections can be in configured state simultaneously.
If you hit this boundary you must select a connection and delete its configuration first.
Action
Action is either Delete for existing (free) entries or Add for new entries.
The routing page consist of two tables: IP address table and IP route table.
The IP address table shows all IP addresses configured on any interface of the Speed Touch. Some of the IP addresses are configured automatically at boot time, others are either manually configured or negotiated on the fly.
To add an IP address, select an interface in the bottom row and specify the address and netmask in dotted decimal notation.
To delete an IP address press the Delete button for a particular entry.
Note: deleting an address automatically removes all related routes.
This tables presents the contents of the routing information base. The routing table contains all routes to all possible destinations and is consulted by the Speed Touch IP router prior to sending or forwarding packets.
Consulting this table can be of help to find out which routes packets will follow.
Similar to the IP address table, a number of routes are preconfigured. Other routes are either added via connection setup (PPP) or via configuration e.g. Classical IP.
In special circumstances routes can be manually added to the routing information base (bottom row of the table). Three fields must be specified: a destination IP prefix, a source prefix and the IP address of the gateway.
Note: an IP prefix is the combination of an IP address and (sub)netmask and e.g. 10.0.0.0/32.
The criteria for a route to be valid is:
The destination and source entries must yield correct prefixes;
The gateway must be directly connected.
Pressing Dial-in will result in the list of PPP connections that are available for PPP-dialling. Please refer to the PPP topic for more information on how to create such connections.
The procedure for using Dial-in connections is as follows:
Surf to the Speed Touch;
Press the Dial-In button;
In the PPP Dial-in Connections table, press action button Dial-In for a particular PPP connection.
If no username and password was configured (and saved) for this link, you will be prompted to enter this information.
The Speed Touch will try to setup a PPP session with its remote PPP peer. The State field will show“Trying” as long as the PPP session is not established. The action button changes to Hang-Up.
If the PPP connection is established, the State field will change from ”Down” into”Up”.
At this point, the Speed Touch is ready to forward and receive data via this connection.
To terminate a PPP session being up or trying, press the Hang-Up button for that particular session.
You arrive at this page by pressing the PPP button on the welcome page.
Note: as routing is supported by the Pro only, this button will have no effect on the Home.
The PPP configuration page allows you to add new PPP entries or to change settings of existing entries.
The default Speed Touch configuration is:
PPP1 configured for dial-in
PPP2 configured for automatic dialling
DHCP_Spoof, a DHCP-to-PPP Spoofing connection
To add a PPP connection, three steps need to be taken:
Create a new entry in the Phonebook with the appropriate VPI/VCI;
Go to the PPP page, select the appropriate entry (by name) and press add;
Press the Config button of the newly added entry for detailed configuration.
Note: prior to adding a PPP connection, the ATM encapsulation can be selected via a listbox. The Speed Touch is compliant with RFC2364 PPP over AAL5 w.r.t. ATM Encapsulation. This RFC mentions two encapsulation methods for PPP: LLC/NLPID and VCMUX. The Speed Touch supports both and default LLC/NLPID is shown in the listbox.
The encapsulation method at the local and remote end of the connection must match for successful communication. Contact you ISP or Corporate administrator to check which encapsulation method is used.
A PPP connection can be configured by pressing Configure for that particular entry.
Basically, this page shows three windows to which parameters can be supplied:
Session related
Routing related
Link related
In the Authentication field you must fill out the username and password supplied by your ISP or Corporate LAN administrator.
As default, a guest account is assumed, i.e. the default username and password are guest. If your ISP has a guest account, you are able to open a session without having an actual subscription.
Via this window you can modify the use of the connection, i.e. Who can use the connection and Which destinations are reachable.
Connection sharing:
This listbox can take three values:
Only me : the PC that established the PPP session “owns” the connection. More specifically, only this PC can forward and accept packets over the connection.
Everybody : is the opposite of the previous bullet: all PC'’s on the local network can use the connection.
My net only : all machines having the same IP network number can use this connection.
Destination networks
This listbox controls the networks that can be reached via this particular PPP connection. The options are:
All networks : if the Speed Touch cannot find a more specific route in its routing table for a given destination, it will forward the packet over this connection.
Remote net only : if a PPP session is established, the IP address of the remote machine is known. Only packets that have matching network numbers will be forwarded over this connection.
Remote host only : if this option is selected you have IP connectivity with the remote host only.
Specific network : it might be that neither of the above fit your requirements. In this case select Specific network. In the input field Specific Network, specify the remote host or network in prefix notation. e.g. 172.16.0.0/16
Local IP or Remote IP
During PPP session setup IP addresses are negotiated. Typically at the client side, these fields are left empty. This forces the client to ask the server for addresses.
To setup the Speed Touch as PPP server, supply suitable values for your network configuration.
Mode
Is either of: Dial-In, Always-on or Dial-On-Demand.
A PPP connection can be established in three ways:
Via the Dial-In page, by manually pressing the Dial-In button of a particular connection;
Automatically when the Speed Touch is booted. This is the Always-On mode in which the Speed Touch automatically tries to establish PPP connections;
In Dial-On-Demand a PPP connection is triggered via specific frames arriving via the Ethernet port.
Idle time limit
If the Idle Time Limit expires, the PPP connection is released. Otherwise stated, if no traffic passes over the PPP connection for Idle Time, the connection is closed.
LCP echo
is a push button turning LCP echo request/replies on or off. If a link is up, PPP issues at regular intervals LCP Echo Requests and expects LCP Echo Replies in return. Default LCP echo is on, allowing to detect whether the remote end went down.
PAP
The default PPP authentication protocol is CHAP (Challenge Handshake Authentication Protocol). Pressing this button will use PAP (Password Authentication Protocol) instead of CHAP.
ACCOMP
ACCOMP is short for Address and Control field COMPression also referred to as ACCM. By default ACCOMP is enabled.
You should disable this option only in special circumstance, i.e. where the remote PPP server expects to see HDLC like framing (FF03 prepended to the PPP packet).
After pressing the CIP button on the Welcome page, you arrive on the Classical IP configuration page.
CIP, short for Classical IP, stems form RFC1577 Classical IP and ARP over ATM. This Internet RFC (Request For Comments) describes how a classical LAN can be created with ATM technology.
This page allows you to change the default CIP configuration or to create new CIP configurations.
Configuring Classical IP in the Speed Touch implies first of all creating a Logical IP Subnet member. Together with the other members on the remote side of the virtual connections, a logical IP subnet is formed. Further in this Help, Logical IP Subnet is abbreviated as LIS and Classical IP as CIP.
Next to creating the CIP member, you must assign the virtual channels that are cross-connected between the local and remote members.
In the CIP Interfaces table add a new CIP member or modify the default. The items of a CIP member exposed in the user interface, are IP address, Subnetmask and ATM address. The ATM resources underneath are of lesser importance for configuration. Note: you can leave the ATM address field blank.
Configure the IP address and (sub)netmask of the CIP member in the bottom row of the CIP Interfaces table and press Add .
If successful, the CIP member is created and a CIP name is automatically assigned. This name serves as a reference in the IP routing page.
Note: make sure the IP address and (sub)netmask are chosen to fit with the other members of the LIS. All members IP addresses must be unique within the LIS and their (sub)netmask must be identical.
After member creation, you must assign virtual channels to it. This can be accomplished in an implicit or explicit manner via the CIP Connections table.
Implicit assignment:
Via the list box in the CIP Connections table, select a preconfigured Phonebook entry. Press Add and the virtual channel is added to the table.
The CIPPVC entry will now change from free to configured in the usage column of the Phonebook.
At this point the Inverse ATM ARP protocol comes into action. By transmitting and receiving InATMARP requests, the Speed Touch discovers the IP address of the remote member.
If the remote members IP address is within the same (sub)network, then the virtual channel is automatically assigned to the CIP client.
In case multiple CIPPVCs are added, the process is repeated.
If the remote member does not fully comply to RFC1577, it will not respond to InATMARP requests. This can be noticed via the status Unresolved in the IP-Address field in the CIP connections table.
At this point the CIPPVC must be explicitly assigned.
Note: unresolved will also pop-up when the remote member is not powered or if the ADSL line is down.
Explicit assignment:
To explicitly assign virtual channels, add the IP address of the remote member in the IP Address field, prior to adding the CIPPVC to the table.
Pressing the PPTP button brings up the PPP-to-PPTP Relay page. Next to IEEE 802.1D Transparent Bridging, PPP-to-PPTP Relaying is a second packet service that is supported by both Speed Touch models.
By default 4 PPP-to-PPTP entries are stored in the Phonebook. The same 4 PPP-to-PPTP connections are displayed in the PPTP Connections table and are ready for use.
PPTP Connections table
This table presents you with relevant PPP/PPTP connection information. The following three fields are given:
Name:
Name refers to a particular ATM Virtual Channel on the ADSL line. By supplying a particular name in the VPN Server input field of the PPTP application on your PC, you are able to choose a virtual channel.
Names can be customized in both the Phonebook and on the Dial-Up icons on your PC'’s. By doing so these might reflect the remote organizations that are connected at the remote end of the virtual channels.
Suppose the Local Operator established 4 permanent virtual channels from your Speed Touch to your corporate headquarters or ISP. You can “name” these virtual channels after your company or favourite Internet Service Provider. e.g.:
|
Name |
|
Alcatel1 |
|
Alcatel2 |
|
Alcatel3 |
|
Alcatel4 |
You can now supply “AlcatelX” (X: 1.. 4) in the Dial-Up icons on your PC'’s desktop. Double clicking the AlcatelX icon on your desktop will connect you to the specified virtual channel in the Speed Touch. If you specify only the first part of the name (e.g. Alcatel), the first available channel matching this name will be used (provided the channel pool is not exhausted).
Encap:
Is short of Encapsulation/Decapsulation and refers to the encapsulation/decapsulation of PPP packets in/from AAL5/ATM. Further down in this paragraph encapsulation/decapsulation will be referred to as encapsulation only for readability.
The Speed Touch is compliant with RFC 2364 “PPP Over AAL5” and supports both the LLC/NLPID method and the VC MUX method. By default the Encapsulation method is set for LLC/NLPID. For successful communication, the Access Server of the remotely connected organization (ISP or Corporation) must use the same method. In case of interoperability problems, contact your ISP or Corporation for more information.
HDLC framing:
PPP packets arriving via a PPTP tunnel and PPP packets encapsulated for transport via ATM virtual channels differ in format. The PPP format on AAL5 is according to RFC 1661 “The Point-to-Point Protocol (PPP)”, see fig.1. The PPP format within a tunnel is according to draft-ietf-pppext-pptp.txt “Point-to-Point Tunnelling Protocol--PPTP”, see fig.2. The latter format has two additional bytes in front of the packet (FF 03) inherited from another encapsulation i.e., RFC 1662 “PPP in HDLC-like framing.

Fig. 2: PPP/PPTP Tunnel format.
In order to cope with these PPP packet differences the Speed Touch adapts the different formats on a per connection base. Although RFC2364 is quite clear regarding PPP format on AAL5, the Speed Touch offers a configuration possibility in case interoperability problems should arise. Note this configuration possibility applies to the ATM/AAL5 encapsulation only! On the Ethernet segment the Speed Touch will always make sure FF-03 is in front of the packet before it is put in a PPTP tunnel.
The PPP/AAL5 formatting options are:
never
The Speed Touch will make sure that FF-03 will never be in front of a PPP packet encapsulated on an AAL5/ATM connection, independent of the actual format in the tunnel. This is the default setting and is according to RFC 2364.
always
The Speed Touch will make sure that FF-03 will always be in front of a PPP packet encapsulated on an AAL5/ATM connection. Although not supported in RFC 2364 some equipment may require this format.
keep
The Speed Touch will not change the PPP packet arriving via a tunnel prior to AAL5 encapsulation. More specifically it will keep the encapsulation that was used in the tunnel independently of the AAL5 encapsulation method.
State:
The Speed Touch allows multiple users to connect to multiple remote organizations simultaneously. However each PPP session takes a virtual channel as it is not possible to multiplex multiple PPP sessions into a single virtual channel.
This implies that each time a PC establishes a PPTP Tunnel/PPP Session, this virtual channel is no longer available to other users.
From the moment a connection is taken, the corresponding State field changes from “IDLE” to “In Use (xxx.xxx.xxx.xxx)”. The number in brackets is the IP address of the PC currently using the connection.
Action:
Is either delete or add. If a connection is in Idle state, pressing Delete will remove the entry from the PPTP Connections table.
In the bottom part of the table you can add entries previously defined in the Phonebook by pressing Add .
The Speed Touch contains an IEEE 802.1D compliant Transparent Bridge that can be reconfigured through this page. In fact for bridging nothing has to be configured prior to connectivity. Via its self-learning and aging mechanism it is a true Plug & Play device.
Important note.
Both the Speed Touch Home and Pro come with four preconfigured bridge entries in the Phonebook (named Br1, Br2, Br3 and Br4). For the Home one bridge entry is added to the Bridge Port table and automatically configured in forwarding state. Otherwise stated : the Home always supports connectivity on one bridge port (e.g. VPI/VCI: 8/35).
Similar to the Home, the Speed Touch Pro has preconfigured bridge entries in the Phonebook. However, the entry stored in the Bridge Port table is in disabled state. This in order to prevent interference form the Bridge with the Router. This implies there is no connectivity on this port. You must put the port into forwarding state prior to connectivity.
Should you experience initial interoperability problems with the remote destination, you can easily change default bridge settings according to the information supplied by the remote organization (ISP or Corporate).
Bridge Configuration Table
What does this table represent ?
Initially the Bridge Configuration Table contains a single bridge entry. In the bottom row you can add the preconfigured Phonebook entries by pressing Action button Add .
Bridge Ports :
One of the characteristic properties of a databridge is the number of supported ports. A bridge port is in fact the logical equivalent of an interface. The Speed Touch supports one local port (Ethernet interface) and at maximum four remote ports. The remote ports are mapped on virtual ATM connections on the ADSL Line.
Only remote ports are shown in the table.
Encap:
Is short of Encapsulation/Decapsulation and refers to the encapsulation/decapsulation of Ethernet or IEEE 802.3 frames in/from AAL5/ATM. Further down this paragraph encapsulation/decapsulation will be referred to encapsulation only for readability.
The Speed Touch is compliant with RFC 1483 Multiprotocol Encapsulation over ATM Adaptation Layer 5. Both the LLC/SNAP method and the VC MUX method for Bridged Ethernet V2.0/IEEE802.3 PDUs are supported.
By default, the Encapsulation method is set to LLC/SNAP. Prior to adding a bridge entry you can change the encapsulation method via the drop down list box. Note, the Access Server of your remote organization (ISP or Corporation) terminating the connection must use the same method. Please contact your ISP or Corporation for information on this topic.
FCS:
Is part of the RFC 1483 encapsulation method and indicates whether the last four bytes of MAC frames (MAC Medium Access Control frames, mostly referred to as Ethernet or IEEE 802.3 frames) will be preserved yes or no.
The FCS of MAC frames will not be preserved and is indicated by NO in the particular column.
State:
The State field allows you to change the state of individual bridge ports. By default each Virtual port is added in the forwarding state.
Forwarding implies that traffic can pass via these ports. You can control the state of individual bridging ports via the drop down box.
Action:
This column contains Action Buttons allowing you to add or delete bridge ports. The maximum number of remote bridge ports that can be added is 4.
Bridge Aging
Via this input, the aging timer of the bridge internal database can be changed. If the aging time of a MAC entry has expired, this entry will be removed from the database.
The default value of 300 s (5 min) should only be changed in exceptional cases. The allowed range is from 10 seconds to 12 days which is compliant with the IEEE 802.1D Bridging standard.
By pressing this button, the Speed Touch will show all MAC addresses in its bridging database.
MAC addresses are spread over two tables:
Permanent MAC addresses are MAC addresses that are always inside the bridge.
Dynamic MAC addresses are learned and aged by the bridge.
Permanent MAC addresses that will be displayed are:
The own MAC address of the Speed Touch : e.g. 00-80-9F-05-0B-A0
The MAC broadcast address : FF-FF-FF-FF-FF-FF
The Bridge Group Address : 01-80-C2-00-00-00
The 16 reserved MAC addresses of IEEE 802.1D : 01-80-C2-00-00-01 through
01-80-C2-00-00-0F
The All LANs Bridge Management Group Address: 01-80-C2-00-00-10
No Static MAC Addresses are configured.
Dynamic MAC Addresses:
All MAC addresses shown in this table are automatically entered and swapped out by the Speed Touch bridge entity. The learning process adds MAC addresses received on any of its ports and the ageing process swaps out addresses that have their ageing timer expired.
DHCP, short for Dynamic Host Configuration Protocol, is a client/server protocol designed for automatic configuration of TCP/IP hosts. Detailed description of the protocol can be found in RFC2131: Dynamic Host Configuration Protocol and RFC2132: DHCP Options and BOOTP vendor extensions.
Both Speed Touch Home and Pro operate in either DHCP client mode or DHCP server mode. Configuring an operating mode is performed by pressing the radio buttons on the DHCP Configuration page.
Always make sure that only one DHCP server is active at the time on the local network. Two servers being active simultaneously will most likely lead to unpredictable configurations.
Note: the DHCP functionality is active on the Ethernetport only.
AutoDHCP
In this mode the Speed Touch probes the local network to verify whether it is the only DHCP server being active. If there is a server on the local network, the Speed Touch assumes the role of DHCP client. If no response is given after Client timeout seconds, the Speed Touch will act as DHCP server.
AutoDHCP is the default DHCP mode of the Speed Touch Pro.
DHCP Client
Press button DHCP Client to activate this mode. In this configuration a DHCP server must be active on the local network. This DHCP server distributes IP configuration information to the DHCP clients on the local Ethernet segment; the Speed Touch being one of them.
DHCP Server
To enable the server mode of the Speed Touch press DHCP Server. In this mode the Speed Touch acts as DHCP server, distributing IP configuration parameters to the machines attached to its Ethernet port.
No DHCP
Press No DHCP to disable DHCP completely. In some circumstances this option might be interesting e.g. if IP addresses are statically assigned.
Default configuration
Home version: in this version, DHCP is disabled by default. If the Speed Touch is going to be used for the PPP/PPTP packet service, it is best to enable the DHCP server. It will make the network Plug & Play.
In the Pro AutoDHCP is enabled by default.
DNS is short for Domain Name System. DNS is a systems allowing to use hostnames for referencing networked computers instead of IP addresses.
DNS in the Speed Touch operates in close co-operation with DHCP. Basically the scenario is as follows:
Assume the Speed Touch is up and running and configured as DHCP Server;
A PC on your local Ethernet segment, configured as DHCP client is powered on. During start-up it will issue a few DHCP requests. Besides asking for IP parameters, it reveals its computername or hostname in these DHCP requests;
The Speed Touch intercepts the requests and returns a DHCP reply. This reply contains IP parameters such as: IP address, Netmask, IP address of Default Gateway, IP Address of Primary DNS server and Domain Name to list a few.
During the request/replies the Speed Touch builds a tiny database containing hostnames and IP addresses. To give an example, assume a computer named “Pluto” gets IP address 10.0.0.1
If some computer on the local network references “Pluto”, then the Speed Touch resolves this name to IP address 10.0.0.1 .
DNS hostname table
Surfing to the Speed Touch’s DNS page, reveals the DNS database.
In case not all computers reveal their hostname in the DHCP request, or even worse if they do not support DHCP, static entries can be added to the local DNS database. To do so, add the IP address and corresponding hostname of these computers via the bottom row of the DNS hostname table.
Care should be taken to keep the database consistent though.
Domain Name
Next to the hostname, a local PC needs the Domain Name to construct a fully qualified domain name. The default domain name the Speed Touch is responsible for, is local.net.
This default domain name can be changed via input field Domain Name .
Server Active
