ipv6 nd stale-time

Configures the stale state timeout for IPv6 neighbors on an interface.
Syntax
ipv6 nd stale-time stale-time-seconds
no ipv6 nd stale-time stale-time-seconds
Command Default

The timeout period is 7200 seconds (2 hours).

Parameters
stale-time-seconds
Specifies the time, in seconds. Valid values range from 120 through 7200 seconds. The default is 7200.
Modes

Interface configuration mode

Usage Guidelines

The configured timeout value is applicable for new neighbors created after the stale state timeout value is altered. The stale state timeout value is not modified for existing neighbors. After the configured stale state interval expires, unused IPv6 neighbors are removed.

The no form of the command removes the configured stale state timeout and restores the default.

Examples

The following example sets the stale state timeout period to 180 seconds for an Ethernet interface.

device# configure terminal
device(config)# interface ethernet 1/1/1
device(config-if-e10000-1/1/1)# ipv6 nd stale-time 180

The following example restores the stale state timeout period to the default of 7200 seconds for a VE interface.

device# configure terminal
device(config)# interface ve 217
device(config-vif-217)# no ipv6 nd stale-time 180
