Command History
Usage Guidelines Sticky ARP entries are those learned on SVIs and Layer 3 interfaces. These entries do not age out.
The ip sticky-arp interface configuration command is only supported on
• Layer 3 interfaces
• SVIs belonging to normal VLANs
• SVIs belonging to private VLANs
On a Layer 3 interface or on an SVI belonging to a normal VLAN
• Use the sticky-arp interface configuration command to enable sticky ARP.
• Use the no sticky-arp interface configuration command to disable sticky ARP.
On private-VLAN SVIs
• When you configure a private VLAN, sticky ARP is enabled on the switch (the default).
If you enter the ip sticky-arp interface configuration command, it does not take effect.
If you enter the no ip sticky-arp interface configuration command, you do not disable sticky ARP
on an interface.
Note We recommend that you use the show arp privileged EXEC command to display and verify
private-VLAN interface ARP entries.
