• View the subnet-prefix of the subnet manager.
• View the Global Unique Identifier (guid) of the subnet manager.
• View the priority for the subnet manager. The priority number of a subnet manager tells the subnet
manager how to interact with other subnet managers; the highest priority subnet manager becomes
the master.
• View the smKey. The smkey is a 64-bit subnet management key that is assigned to the subnet
manager.
• View the admin-status of the subnet manager. The Administrative Status value is enable or
disable. Disabling a subnet manager places it in an inactive state but leaves it intact in the
configuration. The default is enable.
• View the oper-status of the subnet manager. The status is determined by self-detection. The values
are notActive, discovering, or Master. As there is only one subnet manager running on the fabric,
the sm that is running is always designated the master.
• notActive indicates the subnet manager has not been enabled or has been disabled.
• discovering indicates the subnet manager is sweeping the fabric.
• View the act-count of the subnet manager. The Activity counter increments each time the subnet
manager issues a subnet management packet (SMP) or performs other management activities.
• View the status of the subnet manager. The Status may be active or inactive. If active, it is actively
managing subnets. If inactive, it is not managing subnets.
• View the Sweep Interval of the subnet manager. The sweep interval indicates the rate (in seconds)
at which the subnet manager sweeps the fabric for any network changes.
The default is 10 seconds.
• View the Response Timeout of the subnet manager. This is the maximum time allowed between
the port reception of a subnet management packet and the transmission of the associated response.
The default is 2,000 microseconds.
