Monitoring Link State of Management Interfaces in Dual Chassis
By default, Standby Chassis monitors the link state only on data ports (eth<X>-<YZ>).
The Management Monitor feature uses SNMP to monitor management ports for the SSM440 hardware components.
The link state is sent to all SGMs and is integrated with the Standby Chassis High Availability mechanism.
The Management Monitor feature is disabled by default.
To enable this feature, run the "set cluster configuration high-availability mgmt-monitoring on" command in Gaia gClish on the Security Group (see set cluster configuration high-availability).
When the Management Monitor feature is enabled:
-
The monitored management ports are included in the Standby Chassis grade mechanism, according to the predefined factors (default is 11).
-
The output of the "
asg stat -v" command shows the Management ports.See the "
Site Parameters > Ports > Mgmt" line in the output example below. -
The "
show interfaces" command in Gaia gClish shows the link state of management interfaces based on this feature mechanism.

Important: In a Dual Chassis deployment, if the number of SGMs differs between Standby Chassis 1 and Standby Chassis 2, after you activate the monitoring of management interfaces, you must manually adjust the gap in the chassis grade that is required for chassis failover. The grade is calculated from all healthy modules in the system: SGM, SSM, Fans, PSU, and so on. For example:
