I have a customer whose 6500's reboot sometimes. When they do, they create interface vlans 1-700 even though most of them should exist. I was wondering if this is possible:
1. Monitor for a "software forced reboot" in syslog (I got this part)
2. Action to compare the interface vlans in a show ip interface brief to the vlan.dat file
3. Action to delete the interface vlans where they don't appear in the vlan.dat file
It isn't a really big deal for this customer. However, they do currently have to manually remove all of the erroneously created interface vlans. The ones that shouldn't exist are all in a "down/down" state. So, I know they don't exist in the vlan.dat file. This problem also causes a significant spike in their syslog server and monitoring software because it begins monitoring all these interface vlans.
Whatever help you can provide, if this is even possible, i'd appreciate it.
