Arp Timer Aging; Display Arp - H3C s3100 series Command Manual

Static ARP entries are valid as long as the Ethernet switch operates normally. But some operations,
such as removing a VLAN, or removing a port from a VLAN, will make the corresponding ARP
entries invalid and therefore removed automatically.
As for the arp static command, the value of the vlan-id argument must be the ID of an existing
VLAN, and the port identified by the interface-type and interface-number arguments must belong to
the VLAN.
Currently, static ARP entries cannot be configured on the ports of an aggregation group.

Examples
# Create a static ARP mapping entry, with the IP address of 202.38.10.2, the MAC address of
000f-e20f-0000. The ARP mapping entry belongs to Ethernet 1/0/1 which belongs to VLAN 1.
