configure iparp timeout
Description
Configures the IP ARP timeout period.
Syntax Description
| vr_name | Specifies which VR or VRF IP ARP setting to change. |
| minutes | Specifies a time in minutes. |
Default
20 minutes.
If you do not specify a VR or VRF, the current VR context is used.
Usage Guidelines
The range is 0-32,767. A setting of 0 disables timeout.
When the switch learns an ARP entry, it begins the timeout for that entry. When the timer reaches 0, the entry is aged out, unless IP ARP refresh is enabled. If ARP refresh is enabled, the switch sends an ARP request for the address before the timer expires. If the switch receives a response, it resets the timer for that address.
Newly configured ARP timeout values apply only to ARP entries that are learned after the new value is set. Previously learned ARP entries timeout after the previously configured time.
Example
The following command sets the IP ARP timeout period to 10 minutes:
configure iparp timeout 10
