arp timeout (S-, K-Series)

Use this command to set the duration (in seconds) for entries to stay in the ARP table before expiring.

Syntax

arp timeout seconds
no arp timeout seconds

Parameters

seconds Specifies the time in seconds that an entry remains in the ARP cache. Valid values are 0 - 65535. A value of 0 specifies that ARP entries will never be aged out. Default value: 3600 seconds.

Defaults

None.

Mode

Configuration command mode.

Usage

The arp timeout 20 command is explicitly added to the configuration at boot time overriding the default value of 3600 seconds with a value of 20 seconds.

The “no” form of this command restores the default value of 3600 seconds.
