Configuring Service Heartbeat

Service heartbeat is a heartbeat message monitoring system that monitors whether the heartbeat messages are received by the Supervisor card within specified time after the Cisco RFGW-10 line card or TCC card boots up.

The heartbeat messages indicate status of the components to the Supervisor card. If the heartbeat messages are not received within the configured time intervals, then the Supervisor card initiates the appropriate action to resolve the possible issues that may have lead to the heartbeat failure.

Enabling Service Heartbeat

Effective with Cisco IOS-XE 3.2.0SQ, service heartbeat is enabled or disabled using the service heartbeat command. To enable service heartbeat, configure the following service heartbeat parameters with default values in seconds:

  • Warning timeout
  • Fatal timeout
  • Alive timeout

This example shows the configuration that enables service heartbeat:

Router(config)# service heartbeat warning-timeout 3

Router(config)# service heartbeat fatal-timeout 5

Router(config)# service heartbeat alive-timeout 600

Disabling Service Heartbeat

To disable service heartbeat, use the no service heartbeat command. This example shows how to disable service heartbeat:

Router(config)# no service heartbeat

Verifying Service Heartbeat

This example displays an extract of the output of the show running-config command which shows the enabled parameters of service heartbeat.
