Gigabit ports on Catalyst 2950

whitelightrider

Folks,

Is it possible to configure the Gigabit ports on a Catalyst 2950? I can set the IP address for the switch in the VLan 1 part but what about the 2 Gigabit ports?

The 2950 doesnt do routing...

they will be in the configuration as gi0/1 and gi0/2. But depending on the exact model you have, you may need interface modules.

you should be able to use them as normal switch ports without any configuration though

Hi Penfold,

Do I just give the switch an IP Address in the VLAN as usual?

Getting an error:

IP Addresses may not be configured on L2 links.

I think only one vlan can have an ip address, if you gave vlan1 an ip address, you cannot give vlan2 an ip address. The switch can only have one ip address.

You can then add those ports to whatever vlan you want.

What exactly is your end goal here?

As was said, you can only put an IP address on a routed port. On the bigger layer 3 switches, you can turn a switch port into a router port by doing 'no switchport' but on the 2950 that doesnt apply.

Either way, the 2950 wont act as a router, so even if you do create another VLAN interface and put the gigabit ports into it, it wont route between the two vlans

assigning an ip address to other vlans on a layer 2 switch and then placing ports (including your gigabit) into themmay be use if you wish to test/ping for connectivity to a vlan rather than a client pc- otherwise it is as much use as an ashtray on a motorbike;)

You'll need a router attached to do that?

You need a router to route between vlans. If you're not routing between vlans, there's limited reason to assign IPs to individual vlans.
