The user-fqdn command configures a user-fully qualified domain name (USER-FQDN) for IKE peers that are allowed to access.
The undo user-fqdn command deletes the USER-FQDN for IKE peers that are allowed to access.
By default, no USER-FQDN is configured for IKE peers that are allowed to access.
This command is supported only on the NetEngine 8000 F1A.
