Switch:  VLan

Hello Experts,

I have a VLan configuration that I need clarification on.  I have Catalyst switches and two are llink together point-to-point and both are 2924's.  For simplicity, I will call SW1 for switch one and SW2 for switch number two.  Now on SW1 fa0/8 port, this is connected to fa0/8 of SW2 and it is part of vlan 2.  Now on SW1, port fa0/24 is connected to SW2 on port fa0/24 with no vlan assignment.  Is it safe toassume then that this is part of vlan1, the default vlan on a switch?

As always, thank you for your time on this mater.

Why would you have two links between the switches? You can run

conf t
interface fa 0/8
switchport trunk allowed vlan 1,2

If you run this on both switches they will forward traffic for both vlans in both directions. Of course you can split the vlans and configure fa 0/8 for vlan 2 only and fa 0/24 for vlan 1 only.

Hi Kirshi,

Inherited the network and I am attempting to understand as to why it was configure in this manner.  My only assumption is, it was an attempt in combining the ports...instead of a 100Mb pipe it is 200Mb?  I am shooting in the dark here.  Would that be correct assumption?

Yes, that sounds like a good reason. Its just not that simple with switches.
