Aging time of ARP entries on S series switches

For S series switches (except S1700 switches),
the default aging time of dynamic ARP entries is 1200s (20 minutes). You can run the arp expire-time  expire-time command in the system view or an interface view to configure the aging time of dynamic ARP entries. Configure the second expire-time variable as the target aging time of dynamic ARP entries.
Static ARP entries do not age.
