Enables IP ARP to refresh its IP ARP entries before timing out.
| vr_name | Specifies a VR or VRF. |
Enabled.
If ARP refresh is enabled, the switch resends ARP requests for the host at 3/4 of the configured ARP timer value.
For example: If the ARP timeout is set to 20 minutes, the switch attempts to resend an ARP request for the host when the host entry is at 15 minutes. If the host replies, the ARP entry is reset back to 0, and the timer starts again.
If you do not specify a VR or VRF, the command applies to the current VR context.
The following example enables IP ARP refresh:
enable iparp refresh
