Tahoe 4681 (4-port G.shdsl.bis/FastEthernet modem card)
Entering bridge list displays a list of MAC addresses with the name of the interface on which
certain address was heard.
If you select transparent or dumbtrans mode while being connected to the modem via telnet you
will loose the possibility of remote management (the modem will stop responding to its IP address).
Thus you’ll be unable to change that setting back to
on or off remotely – you’ll have to change it lo-
cally by the serial console or built-in keyboard and LCD display.
To enable bridging the Cisco® HDLC link protocol should also be selected using the bundle or dsl
command (selected as factory default)
bundle
The bundle command allows grouping of several DSL lines into bundles and configures them.
There are four WAN interfaces – wan0, wan1, wan2 and wan3.
bundle < interface > add < line number >
– adds a line to a bundle:
Tahoe> bundle wan0 add 1
bundle < interface > del < line number >
– removes a line from a bundle:
Tahoe> bundle wan0 del 1
bundle < interface > link { hdlc | raw | fr | ppp }
– selects the link protocol
– Cisco® HDLC, raw HDLC, Frame Relay or synchronous PPP. The Cisco® HDLC proto-
col („hdlc” option) should be used in most cases, the others are provided for compatibility
only
bundle

interface

speed
<
value
>
– sets total throughput of a bundle. The speed
range depends on number of lines belonging to the bundle, i.e. 64 - 5696 kbps in case of one
line, 128 - 11392 kbps in case of two lines, etc. New speed is set after renegotiating the DSL
connection.
bundle < interface > type { master | slave }
– selects modem type of all lines in
the bundle. New type is set after renegotiating the DSL connection. One modem should be
set as a Master, while the other one as a Slave
bundle < interface > mod { auto | tcpam32 | tcpam16 | tcpam8 | tcpam4
| pam16 | pam8 | pam4 | pam2 }
– selects line coding (modulation type) of all lines
in the bundle. The TCPAM32 modulation is recommended, as it is the most efficient – the
