6509 vlan configuration missing

Hi Prashant,

Typically all vlan related configuration will reside on the vlan.dat file which will be in NVRAM.

Do you see this file?

Also, is VTP running? if so, what mode was it on earlier ?

Also was their any topology change recently which would have caused to overwrite the Vlan configuration?

Thanks,

-Vijay

VTP is transparent. Only one vlan(L2) of around 30 vlans was missing. There was no change in topology. There was a issue in power source due to which the switch rebooted. Configurations were saved and this vlan is been into exsistance since a year or more.

Yes, Services were restored after re-entering the configuration. Wanted to know if any command to be executed to check for the misbehaviour.
