DESCRIPTION
This field displays whether MSTP is activated on the device.
This is the unique identifier for this bridge, consisting of bridge priority plus MAC
address. This ID is the same in ExtRootID if this device is the root switch.
This is the time since the spanning tree was last reconfigured.
This is the number of times the spanning tree has been reconfigured.
The spanning tree is currently reconfiguring if "True" displays.
This is the unique identifier for the port that connects to the external root bridge.
This is the unique identifier for the external root bridge, consisting of bridge priority
plus MAC address.
This is the path cost of the link to the root bridge.
This is the maximum time (in seconds) the spanning tree can wait without receiving
a configuration message before attempting to reconfigure on the root port.
This is the time interval (in seconds) at which the root transmits a configuration
message through the root port. The root bridge determines the Hello Time, Max Age
and Forward Delay.
This is the time (in seconds) the root bridge will wait before changing states (that is,
listening to learning or learning to forwarding) on the root port. Each change in
states requires the forward delay time before the change.
