Hello,

 

how old is the switch ? The 6509-E has been around for a very long time as far as I recall. Bus errors are usually not a good thing and often indicate some sort of hardware issue. I also looks like you are running very outdated software (12.2), you might want to upgrade to a 15.x release...
