Connecting Cisco 3550 w/ GBIC copper to 2950 1000base T

Trying to connect these 2 switches together and no luck.  I do have 2 VLAN's but only using the 1 on the 2950.  Have a crossover cable connecting and same gateway etc...  I have a similiar config at another site, but not using GBIC's or 1000 Base T, so not sure if that changes the rules???  Thanks - Jeff

Your problem is that you've got a VLAN mismatch between the switches.

The g0/2 port on the 3550 is an access port in VLAN 2.

The g0/2 port on the 2950 is an access port in VLAN 1

They need to be in the same VLAN. Since the management of the 2950 is using VLAN 1, you'll need to change the 3550 port g0/2 so it's in VLAN 1.

Or you could make the link between the switches a trunk.

When you say "no luck", what exactly do you mean?

Are you not getting a link light?
Do you have an amber link light?
Do you have a green link light but no traffic is passing.

You'll have to be more specific.

It may also help if we can see the configs for the ports on the two switches.

I am getting "Green" link lights on both ends but can't ping each other.  I am working on posting both configs.  Here is the "core" 48 port config.

Please identify what port on each switch is connected to the other switch.

Do you have a VLAN interface with an IP address of the 2950?

If you issue the "show cdp neighbor" command, do you see the other switch?

DON you are THE MAN!  Not that familiar with Cisco or VLAN's for that matter obviously!  I switched the 2950 over to VLAN 2 and changed the ports over to that and off it went!  Perfect!!!  Thank you for all your help especially on a Sunday.
