ARP
The nv unset commands remove the configuration you set with the equivalent nv set commands. This guide only describes an nv unset command if it differs from the nv set command.
nv set system global arp base-reachable-time
Configures how long a neighbor cache entry is valid. The entry is considered valid for at least the value between the base reachable time divided by two and three times the base reachable time divided by two. You can specify a value between 30 and 2147483 seconds. The default value is auto; NVUE derives the value for auto from the /etc/sysctl.d/neigh.conf file.
