This policy defines how the mgmt0 Ethernet interface on the fabric interconnect should be monitored. If Cisco UCS detects a management interface failure, a failure report is generated. If the configured number of failure reports is reached, the system assumes that the management interface is unavailable and generates a fault. By default, the management interfaces monitoring policy is disabled.
If the affected management interface belongs to a fabric interconnect which is the managing instance, Cisco UCS confirms that the subordinate fabric interconnect's status is up, that there are no current failure reports logged against it, and then modifies the managing instance for the end-points.
If the affected fabric interconnect is currently the primary inside of a high availability setup, a failover of the management plane is triggered. The data plane is not affected by this failover.
You can set the following properties related to monitoring the management interface:
Type of mechanism used to monitor the management interface.
Interval at which the management interface's status is monitored.
Maximum number of monitoring attempts that can fail before the system assumes that the management is unavailable and generates a fault message.
In the event of a management interface failure on a fabric interconnect, the managing instance may not change if one of the following occurs:
A path to the end-point through the subordinate fabric interconnect does not exist.
The management interface for the subordinate fabric interconnect has failed.
The path to the end-point through the subordinate fabric interconnect has failed.
