Catalyst has 'ip dhcp snooping database' command to save as a file. Cannot find similar command on the Nexus. Without it, wouldn't a reboot cause the DB to come up empty, triggering arp inspection and source guard for legitimate traffic?
In the recently releases by default DHCP bindings are not saved persistently across switch reboots. To maintain persistent bindings across switch reboots, use the copy run start command.
When the copy run start command is issued, all bindings that exist at that time are made persistent across switch reboots.
Thank you very much for the response, Richard! I cannot find this mentioned in the N7K 6.x Security Configuration Guide. Do you have a reference I can point students to?
