Configuring a long static ARP entry
About long static ARP entries
Long static ARP entries can be effective or ineffective. Ineffective long static ARP entries cannot be used for packet forwarding. A long static ARP entry is ineffective when any of the following conditions exists:
The corresponding VLAN interface or output interface is down.
The IP address in the entry conflicts with a local IP address.
No local interface has an IP address in the same subnet as the IP address in the ARP entry.
A long static ARP entry in a VLAN is deleted if the VLAN or VLAN interface is deleted.
