Title: Cisco vlan.dat backup
Post by: networkbo on July 20, 2021, 06:04:32 pm

Is it possible to backup vlan.dat file from Cisco core switches on NeDi?
To backup only configuration is not enough for core switches when using vtp.

No, it should be generated and maintiained by the startup-config.
Is that not the case on a VTP server? Sorry, I've always used transparent...

I think vlan.dat backup is needed for vtp servers
https://www.cisco.com/c/en/us/support/docs/switches/catalyst-2940-series-switches/109304-manage-vlandat.html
If the startup VTP mode is server mode, or the startup VTP mode or domain names do not match the VLAN database, VTP mode and VLAN configuration for the first 1005 VLANs are selected by VLAN database information, such as the vlan.dat file. VLANs greater than 1005 are configured from the switch configuration file.
In "Backup and Restore of vlan.dat File" section  I read "In order to perform a complete backup of your configuration, include the vlan.dat file in the backup along with the configuration."
