archiving/recovery of vlan database

Is there a method to archive the vlan.dat file for recovery. If so is there a recovery procedure for using the archived file if the original is corrupted or deleted. Where does the vlan.dat file reside in the file structure on a 6513?

Re: archiving/recovery of vlan database

You can back it up to a TFTP server/bootflash. In a 6500 running native IOS, it is stored in the const_nvram section. If you are using newer IOS on your 6500 and using VTP transparent mode, you can save the VLAN information in the startup config by using global configuration mode to configure VLANs

C6506-A1#dir const_nvram:

Directory of const_nvram:/

1 -rw- 0 vlan.dat

129004 bytes total (129004 bytes free)

C6506-A1#copy const_nvram:vlan.dat ?
