Cisco Systems 3825 manual Keepalive, Period 10 seconds

Appendix A Cisco 3825 Mobile Wireless Edge Router RAN-O Command Reference

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.

keepalive [period [retries]]

no keepalive [period [retries]]

Syntax Description	period	(Optional) Integer value in seconds greater than 0. The default is 10.
	retries	(Optional) Number of times that the device will continue to send keepalive
		packets without response before bringing the interface down. The integer
		value is greater than 1 and less than 255. If omitted, the value that was
		previously set is used; if no value was specified previously, the default value
		of 5 is used.
		If this command is used with a tunnel interface, then this variable specifies
		the number of times that the device will continue to send keepalive packets
		without response before bringing the tunnel interface protocol down.
