Hi everyone,
i must have to read a config file from a 2830 series, to replicate it in a 2860. But i hove only a backup file and the router is broken.
Can anyone help me?

So long as the 2830 was running version 3.6.6.2 or later, the 2860 can read its config. backup directly. (It disables LAN<>VLAN after import, because of the different no. of ports).

This information is from the 2860's GUI @ "System Maintenance >> Configuration Backup", but you have to scroll down the page to see it :idea:

Sorry i have a 2760

Check with support to see if they can help. It's not possible to load the config from a Vigor 2760 onto a 2860, I think.
