keepalive
keepalive
To enable keepalive packets and to specify the number of times that the Cisco IOS software tries to send
keepalive packets without a response before bringing down the interface or before bringing the tunnel
protocol down for a specific interface, use the keepalive command in interface configuration mode.
When the keepalive function is enabled, a keepalive packet is sent at the specified time interval to keep
the interface active. To turn off keepalive packets entirely, use the no form of this command.
Syntax Description
period
retries
Defaults
period: 10 seconds
retries: 5
If you enter only the keepalive command with no arguments, defaults for both arguments are used.
If you enter only the keepalive command and the timeout (period) parameter, the default number of
retries (5) is used.
If you enter the no keepalive command, keepalive packets are disabled on the interface.
