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
