how to console multiple routers from a Single Telnet/console Session

Dear all,

i do have 3 2600 series, one 1750 and one 1650 routers for my lab experiments. all of them having WIC 2 T installed. other specifications are usual. one ethernet, one aux, console ports.

how can i connect to all of them, using a single telnet or console session to a main router. i have heard about comm. server. but all documents explains about connecting through sync/async connections.

in one of the 2600 series router i do have 2 WIC2T( which makes 4 smart serial connections)

please let em know.

regards

Mohammed

Re: how to console multiple routers from a Single Telnet/console

You can use reverse telnet where you connect a console cable from the aux port to the console port of the routers in a daisy-chain config , you then connect from the one to the other by issueing the telnet command with a specific port number. Here is an example :

You issue a show line command , the aux port is listed as port 5 on a 1750 for instance. You connect a console cable from the aux port of this router(R1) to the console port of the next router (R2). On the aux port of the router issue the following commands : Transport input all and no exec.

Issue a telnet command using an ip address local to r1 combined with the port number of the aux port plus 2000 fori nstance :

IP address 10.10.10.1 is a local ip on R1 the aux port is line number 5 so the command would be : telnet 10.10.10.1 2005.

The will allow you to connect to R2 via reverse telnet . You can do this for number of routers but be carefull of too many as it gets confusing.
