Any clue why all configuration under the interfaces e.g portchannel etc.. lost after i truned both the switches ON ( active switch switchover ) after some days. I turned them off before going to vacations (they are not in production yet ). Have done many reloads and tested active/standby switchovers previously without any issue.
Solved! Go to Solution.
We were experiencing an issue where the startup config was erased on both switches in a virtual stack on power on from cold. This only happened at random and eventually TAC identified a bug:
We have tested and this has resolved the issue.
Did you save your configuration?
sh switch detail
We have the same issue. We have had two different pairs of 9407 exhibit the same behaviour. We have established that it is something to do with StackWise as the problem does not occur in non-stacked configurations. We had raised a case with TAC when we first saw it but they were unable to recreate the problem. We got the second pair of switches in last week and saw the problem straight away. Are waiting to progress with TAC so I will post what they say.
