Enable Iparp Refresh - Extreme Networks ExtremeWare XOS Command Reference Manual

IP Unicast Commands

enable iparp refresh

enable iparp {vr <vr_name>} refresh
Description
Enables IP ARP to refresh its IP ARP entries before timing out.
Syntax Description
vr_name Specifies a virtual router.
Default
Enabled.
Usage Guidelines
IP ARP refresh is used so that the switch does not have to wait for the ARP timer for a host to expire
before re-ARPing for the host. If ARP refresh is enabled, the switch will re-ARP for the host at 3/4th of
the configured ARP timer.
For example: If the ARP timeout is set to 20 minutes, the switch will attempt to re-ARP 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 virtual router, the command applies to the current virtual router.
Example
The following command enables IP ARP refresh:
enable iparp refresh
