DESCRIPTION
Unique identifier for this bridge, consisting of bridge priority plus MAC address.
This ID is the same in Designated root ID if MSAP2000 AAMS is the root
switch.
This ID is the same in Our bridge ID if the MSAP2000 AAMS is the root switch.
This is the number of times the spanning tree has been reconfigured.
This is the path cost from the root port on this MSAP2000 AAMS to the root witch.
This is the priority and number of the port on the MSAP2000 AAMS through
which this MSAP2000 AAMS must communicate with the root of the Spanning
Tree. "0x0000" displays when this device is the root switch.
This is the maximum time (in seconds) the root switch can wait without receiving
a configuration message before attempting to reconfigure.
This is the time interval (in seconds) at which the root switch transmits a
configuration message. The root bridge determines Hello Time, Max Age
and Forwarding Delay.
This is the time (in seconds) the root switch will wait before changing states
(that is, listening to learning to forwarding).
This is the maximum time (in seconds) the AAM can wait without
receiving a configuration message before attempting to reconfigure.
This is the time interval (in seconds) at which the AAM transmits a
configuration message. The root bridge determines Hello Time, Max
Age and Forwarding Delay.
This is the time (in seconds) the MSAP2000 AAMS will wait before changing
states (that (second) is, listening to learning to forwarding).
This identifies the MSAP2000 AAMS's ports that support the use of STP.
This field displays the port's RSTP (or STP) state. With RSTP, the state can
be discarding, learning or forwarding. With STP, the state can be
disabled, blocking, listening, learning, or forwarding.
Disabled appears when RSTP has not been turned on for the individual port or
the whole device.
This is the priority and number of the port on the MSAP2000 AAMS through
which this MSAP2000 AAMS must communicate with the root of the Spanning
Tree. "0x0000" displays when this device is the root switch.
This is the path cost from this port to the root switch.
This is the path cost from the root port on this MSAP2000 AAMS to the root
This is the unique identifier for the bridge that has the lowest path cost to reach
the root bridge, consisting of bridge priority plus MAC address.
This is the port on the designated bridge that has the lowest path cost to reach
the root bridge, consisting of bridge priority.
The text box displays how often (in seconds) this screen refreshes. You
may change the refresh interval by typing a new number in the text box
and then clicking Set Interval.
Click Stop to halt STP statistic polling.
