Hello All,
In one of our locations we are running the following switch stack as shown below. We would like to remove one of the switches from the stack. I was originally thinking this was going to be a fairly simple process without causing any downtime, since we were able to already remove all the devices off one of the switches. But, it sounds like a reconfiguration might be needed from what I read.
3 Switch Stack:
NAME: "c92xx Stack", DESCR: "c92xx Stack"
PID: C9200-24T-E , VID: V01 , SN: JAD23******
NAME: "Switch 1", DESCR: "C9200-48P-E"
PID: C9200-48P-E , VID: V01 , SN: JAD23******
NAME: "Switch 2", DESCR: "C9200-48P-E"
PID: C9200-48P-E , VID: V01 , SN: JAD23******
NAME: "Switch 3", DESCR: "C9200-24T-E"
PID: C9200-24T-E , VID: V01 , SN: JAD23******
We were able to remove all devices connected to what we have labeled as Switch 1 (*except for the uplink port). However, I'd like to confirm for sure that what we have physically labeled as switch 1, is indeed Switch 1 logically in the config.
These 3 switches connect back to our Cisco 9500 core switch. Running 'sh cdp nei' on the 9500 core shows the 9200 connected to 3 ports on the core. The person who set this up is no longer with the company, so I'm not 100% sure on this... It appears that Switch 1 (*Te 1/1/1) and Switch 2 (*Te 2/1/1) connect back to the Core as trunk ports (*and they're part of a port-channel).
However, Switch 3 has an odd configuration and I'm not sure why it was setup this way. But, the Core side is configured with a Vlan we use for our BYOD Wi-Fi and the Switch 3 side shows "switchport access vlan 900", which is what we use when we connect an ISP connection to our switches.
*BTW, I'm not physically located where these switches are to visually confirm.

3 OK OK 1 2So is there any possible way to get one of these switches removed without causing downtime? Of these 3 switches, Switch #3 which is the 24-port switch is the most important, as it has multiple ISP's connected to it, as well as an EPL link.
Any help would be greatly appreciated!
Thanks in Advance,
Matt
