STACK DISABLED MASTER MONITORING

stack disabled-master-monitoring

Overview This command enables the Disabled Master Monitoring (DMM) feature. If a stack
member becomes a disabled master, the DMM feature will use the stack resiliency
link to continue monitoring the health of the separated stack master.
Use the no variant of this command to disable the DMM feature.
Syntax stack disabled-master-monitoring
no stack disabled-master-monitoring
Default By default, Disabled Master Monitoring is enabled. However, it only operates if
there is a resiliency link.
Mode Global Configuration
Usage This command enables additional stack resiliency link functionality, which is used
if a stack separation occurs. For DMM to operate, a resiliency link must also be
configured
stack member becoming a disabled master, which has the configuration as a
normal stack master except that all its switchports are shutdown.
For more information about the disabled master state, see the
Overview and Configuration
When the DMM feature is enabled, the disabled master will continue to monitor
the health of the original stack master over the stack resiliency link connection. If
the original stack master were to fail, when the DMM feature is enabled, then the
disabled master will detect this and will automatically re-enable its switchports.
This ensures that the stack will continue to pass network traffic, even if a
catastrophic stack failure occurs.
For more information about the DMM feature when the stack member is a disabled
master, see
Examples To enable the DMM feature, use the following commands:
awplus#
awplus(config)#
To disable the DMM feature, use the following commands:
