I currently have a Catalyst 4506 and I have two open fiber gigabit ports, which I'd like to use. All of my other ports and all my Vlans are already configured. This was done by an outside complany, so now I'm trying to expand upon what they did, but I'm having some difficulty. Here is a section of the current config:
description "Trunked Link to Lib"
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,40,60,70
switchport mode trunk
switchport trunk allowed vlan 1,20,60,70
description Not on Visio
Interfaces 3/1 and 3/2 should look like interface 2/6 with the exception of a different vlan (172) and a different description. I've tried going into configuration mode and making changes to the interface, but they never seem to actually change anything, as this is the same config as it's been. I'm relatively new to this, and need some help. If anyone can tell me what commands to use to change this config, I'd greatly appreciate it. Again, it should mirror interface 2/6 just with a different decscription, and with vlan 172 only.
