I'm just getting started with Cisco and have a pair of 2950(s) with SFP ports cabled together. In order to do maintain/configure both switches from one or the other switch I need to establish communication through the SFP port. Otherwise I'm having to change my console cable. I'm going to research but any insight is appreciated.
Yes, you either need to hop between the switches or communicate through the SFP. If you want to communicate through the SFP, here is something you could do:
First access both switches through console and configure an IP address for VLAN 1. Then configure the SFP port to be on VLAN 1. Now connect the SFP ports and make sure that you have connectivity between both switches. Enable telnet on both switches:
line vty 0 4
transport input all
enable password cisco
Now you can connect to one of the switches through console and telnet to the other via the switch. If you need to configure the SFP port as trunk, configure the remote switch first with VLAN 1 as the native vlan and then configure the local switch. In that way, you will maintain connectivity.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
