Managing high availability heartbeat messages on a NetScaler appliance

February 20, 2019

The two nodes in a high availability configuration send and receive heartbeat messages to and from each other on all interfaces that are enabled. The heartbeat messages flow regardless of the HA MON setting on these interfaces. If NSVLAN or both (NSVLAN and SYNC) are configured on an appliance, the heartbeat messages flow only through the enabled interfaces that are part of the NSVLAN and SYNCVLAN.

If a node does not receive the heartbeat messages on an enabled interface, it sends critical alerts to the specified Command Center and SNMP managers. These critical alerts give false alarms and draw unnecessary attention from the administrators for interfaces that are not configured as part of the connections to the peer node.

To resolve this issue, the HAHeartBeat option for interfaces and channels is used for enabling or disabling HA heartbeat-message flow on them.

To manage the high availability heartbeat messages on an interface by using the command line interface

At the command prompt, type:

set interface <ID> [-HAHeartBeat ( ON | OFF )]
show interface <ID>

To manage the high availability heartbeat messages on a channel by using the command line interface

At the command prompt, type:

set channel <ID> [-HAHeartBeat ( ON | OFF )]
show channel <ID>

To manage the high availability heartbeat messages for an interface by using the GUI

Navigate to System > Network > Interfaces.
Enable or disable the HA Heart Beat parameter.

To manage the high availability heartbeat messages on a channel by using the GUI

Navigate to System > Network > Channels.
Enable or disable the HA Heart Beat parameter.
