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 32,767 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.
Applicable Platforms
This command applies to the NetVanta 300, 1000R, 2000, 3000, 4000, and 5000 and Total Access 900
Series units.
Command History
Release 9.1 Command was introduced.
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
