•
No local interface has an IP address in the same subnet as the IP address in the ARP entry.
If you specify the
vlan-id interface-type interface-number
argument, follow these
restrictions and guidelines:
•
The interface can be an Ethernet interface or an aggregate interface.
•
The VLAN and VLAN interface must already exist. The specified Ethernet interface must belong
to the specified VLAN.
•
The IP address of the VLAN interface and the IP address specified by the
ip-address
argument must be on the same network.
•
A long static ARP entry for a VLAN is deleted if the VLAN or VLAN interface is deleted.
Examples
# Configure a long static ARP entry that contains IP address 202.38.10.2, MAC address
00e0-fc01-0000, and output interface GigabitEthernet 1/0/1 in VLAN 10.

Usage guidelines
Each dynamic ARP entry in the ARP table has a limited lifetime, called an aging timer. The aging
timer of a dynamic ARP entry is reset each time the dynamic ARP entry is updated. Dynamic ARP
entries that are not updated before their aging timers expire are deleted from the ARP table.
