R211x-HP Flexfabric 11900 Layer 3 - IP Services Command Reference

A static ARP entry is effective when the device works correctly. However, if the VLAN or VLAN interface
to which an ARP entry corresponds is deleted, the entry is deleted if it is long. If it is short and resolved,
the entry becomes unresolved.
A resolved short static ARP entry might become unresolved upon certain events. For example, it is
unresolved if the output interface is down.
A long static ARP entry is ineffective when the corresponding VLAN interface or output interface is down.
An ineffective long static ARP entry cannot be used to forward packets.
The Ethernet interface following the vlan-id argument must belong to the VLAN. You must first create the
VLAN interface of the VLAN.
If you specify both the vlan-id and ip-address arguments, the IP address of the specified VLAN interface
must be in the same network as the specified IP address.
If you do not specify any VPN, the undo arp command only removes ARP entries for the public network.
Examples
# Configure a static ARP entry that comprises IP address 202.38.10.2, MAC address 00e0-fc01-0000,
and output interface Ten-GigabitEthernet 1/0/1 in VLAN 10.
