These error messages occurred on a Cat4006 w/ Sup II this weekend causing part of my network to drop. Although resetting the switch fixed the problem, I am going to have questions on Monday as to why it happened. The website says that it means the Supervisor lost communication with a component on a 10/100 card but doesn't explain much more than that. Has anyone seen this error before and can explain to me where to start looking for the cause? Everything I see on the show tech looks good but obviously something happened.
We had problems with our 4006 on Sunday generating the Astro message, but unfortunately it was reloaded before I could record the message. On reloading, the switch stayed down until I powered off the switch and re-seated the Supervisor (SEIII) module. I would be interested to know if spanning tree is an issue as we have replaced this switch in the last 3-6 months because of this problem.
