trying to locate a cisco command for eth.port config

[denodave]

I have two 1602 routers, one with 12.x IOS the other with 11.x and I was poking around in some configuration commands. On one router (only on one, and I think it was the ios v12.x) I came across a command which appeared to setup an eth.port to carry multiple ip adresses. Or, it might have been multiple sessions...the net effect appeared to be to cause the one port to function as a multi-addressed connection. Which should allow it to multi-session, correct? It was really late and I neglected to write down what command menu it was located in, now I CAN'T FIND IT! I recall it was "near" fast-switching commands, but I just can't locate it. Any help is REALLY appreciated! Email me! denodave@yahoo.com

Two possible options

at the interface configuration
ip address aaa.aaa.aaa.aaa mmm.mmm.mmm.mmm secondary
This will add a secondary IP address on the interface

encapsulation (dot1q | isl)
this will allow you to create sub interfaces each with a separate IP address.

Option 1 puts both IP addresses on the same "segment"
Option 2 creates logical segments on a single wire. Any device attached to this segment will need to understatnd the encapsulation

Hope This Helps

Thanks commsbloke, I am going to check this out later, it's now 2am and time to go. BUT DON'T LET THIS STOP ANY MORE SUGGESTIONS from coming in.

QUESTION: the second part, dot1q | isl , do you know of a reference that explains the syntax and form of this?

For that matter does anyone know of a public reference that explains cisco commands, their sub-commands, purposes, etc. in a dictionary-like format? Email me! denodave@yahoo.com

OK, that wasn't it.

What I was doing was entering commands thusly "commandxyz ?" and reading the various subcommands and descriptions -- then I'd enter a subcommand "subcommandxyz ?" to see that response, and so on and so forth. In this manner I could not have arrived at the command listed above, being that I was not entering any extraneous or config-changing data. I was just window-shopping.

ANYONE OUT THERE KNOW WHERE I CAN FIND THIS INFORMATION? Email me! denodave@yahoo.com
