I have a pair of Cisco 2960-X's in a stack configuration using stack modules. This gives me a total of 4, 10 gbps SFP+ slots. I am using interfaces
Te2/0/1 as 10 gbps uplinks to the core and previously had
Now I need to add a 1 gbps link coming off of one of these switches out to another device which only supports 1 gbps fiber SFP modules. I hooked up a 1 gbps SFP module to the
Te2/0/2 interface, however it continued to show the type as "Not Present".
After working at it for a bit I reloaded the switch to find that the list of interfaces had changed to now show a
Gi2/0/50 while now missing
Te2/0/2. (As a side note the
Gi2/0/49 interface shows "Not Present" while the
Te2/0/1 interface shows the 10 gbps SFP+ module).
Gi2/0/50 now shows the 1 gbps SFP and works correctly.
Is there any way for the switch to perform this detection process without having to reboot it? I may have to swap these around again in the near future and I would rather not cause downtime for the other systems that are plugged into that switch if it can be avoided.
