Configure a VLAN

[stuman19]

I need the commands in order to configure a vlan on a cisco router. I have to do documentation for a class for college (getting my networking degree). They are rack mounted cisco routers. Everything is done via hyperterminal. It would be nice to know some commands on how to configure em. Maybe a link to help out. Thanks people.

router's don't do vlans, that's a switch thing.

can you give some more information?

 

[cmetz]

interface fastethernet 1/1.x
encapsulation dot1q y

where x is a subinterface number (local) and y is the 802.1q tag.

OH!

You mean trunking.

Right VLANs are used in a switched environment to seperate broadcast domains and retain some security. But how do you set it up on a switch involving a router too? I need to know the right commands. Also can someone explain the subinterfaces?

 

[Poontos]

In Frame Relay (most of which applies to regular sub interfaces), sub interfaces are:

-Logical subdivisions of a physical interface

-Each PVC can be configured as a point to point connection

-Sub int. acts as a dedicated line

-S0/0.1 , s0/0.2, etc...

-Connectivity costs can be reduced by using sub interfaces...


Would a one armed router help?
