ip sticky-arp (interface configuration)
• If you disconnect the switch from a device and then connect it to another device with a different
MAC address but with the same IP address, the ARP entry is not created, and this message appears:
*Mar 2 00:26:06.967: %IP-3-STCKYARPOVR: Attempt to overwrite Sticky ARP entry:
20.6.2.1, hw: 0000.0602.0001 by hw: 0000.0503.0001
• If a MAC address of a device changes, you must use the no arp ip-address global configuration
command to manually remove the private-VLAN interface ARP entries.
• Use the arp ip-address hardware-address type global configuration command to add a
private-VLAN ARP entry.
• Use the no sticky-arp global configuration command to disable sticky ARP on the switch.
• Use the no sticky-arp interface configuration command to disable sticky ARP on an interface.
Examples To enable sticky ARP on a normal SVI:
Switch(config-if)# ip sticky-arp
To disable sticky ARP on a Layer 3 interface or an SVI:
Switch(config-if)# no ip sticky-arp
You can verify your settings by using the show arp privileged EXEC command.
