HP 7000 dl Router manual Keepalive period retries, Config#interface tunnel

Command Reference Guide Tunnel Configuration Command Set

keepalive <period> <retries>

Use the keepalive command to periodically send keepalive packets to verify the integrity of the tunnel from end to end. Use the no form of this command to disable keepalives.

Syntax Description

<period>	Defines the time interval (in seconds) between transmitted keepalive packets
	(valid range: 1 to 32767 seconds).
<retries>	Defines the number of times to retry after failed keepalives before determining
	that the tunnel endpoint is down (valid range: 1 to 255 times).

Default Values

By default, keepalives are disabled. When enabled, the keepalive period defaults to 10 seconds and the retry count defaults to 3 times.

Command Modes

(config-tunnel x)# Tunnel Interface Configuration Mode

Functional Notes

Keepalives do not have to be configured on both ends of the tunnel in order to work. A tunnel is not aware of incoming keepalive packets.

Usage Examples

The following example enables keepalive with a period of 30 seconds and a retry count of 5 times:

(config)#interface tunnel 1

(config-tunnel 1)#keepalive 30 5
