Configuring DHCPv6 snooping entry auto backup
The auto backup feature saves DHCPv6 snooping entries to a backup file, and allows the DHCPv6
snooping device to download the entries from the backup file at reboot. The entries on the DHCPv6
snooping device cannot survive a reboot. The auto backup helps the security features provide
services if these features (such as IP source guard) must use DHCPv6 snooping entries for user
authentication.
IMPORTANT:
If you disable DHCPv6 snooping with the undo ipv6 dhcp snooping enable command, the device
deletes all DHCPv6 snooping entries, including those stored in the backup file.
