Hello, I have a WS-C3548-XL-EN switch running ios v12.0(5)WC17 (fc1) that I can not get to connect into a community in CNA v6.1. I have reset the switch to 'factory defaults', set the IP, SNM, and Default gateway. From other posts I saw that from the...

I too have this problem. On top of this, ALL versions (as far as I can tell) that are pre 12.2(35)SE have been designated as 'deferred releases' so there is no way to go back. What are the options?

Leo, Thank you for replying.That is a good question. This switch is one that our corporate IT department had on a shelf. I know we have some level of a contract with Cisco, just not sure if this switch is covered.As I write this, the switch came back...

Leo,There was a glimmer of hope that was quickly dashed. Switch 1 (now disconnected from stack with cable between stack port 1 and 2) booted, ran for 30 -120 seconds then got the same %Software-forced reload. I had something going on in there so I ha...
