MSAP2000 AAMS User’s Guide

Table 35 Spanning Tree Protocol: Status (continued)

LABEL	DESCRIPTION
Our bridge ID	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.
Designated root ID	Unique identifier for the root bridge, consisting of bridge priority plus MAC address.
	This ID is the same in Our bridge ID if the MSAP2000 AAMS is the root switch.
Topology change	This is the number of times the spanning tree has been reconfigured.
times
Time since change	This is the time since the spanning tree was last reconfigured.
Cost to root	This is the path cost from the root port on this MSAP2000 AAMS to the root witch.
Root port ID	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.
Root max age	This is the maximum time (in seconds) the root switch can wait without receiving
(second)	a configuration message before attempting to reconfigure.
Root hello time	This is the time interval (in seconds) at which the root switch transmits a
(second)	configuration message. The root bridge determines Hello Time, Max Age
	and Forwarding Delay.
Root forward delay	This is the time (in seconds) the root switch will wait before changing states
(second)	(that is, listening to learning to forwarding).
Max age (second)	This is the maximum time (in seconds) the AAM can wait without
	receiving a configuration message before attempting to reconfigure.
Hello time	This is the time interval (in seconds) at which the AAM transmits a
(second)	configuration message. The root bridge determines Hello Time, Max
	Age and Forwarding Delay.
Forward delay	This is the time (in seconds) the MSAP2000 AAMS will wait before changing
	states (that (second) is, listening to learning to forwarding).
Port Status	This identifies the MSAP2000 AAMS’s ports that support the use of STP.
State	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.
Port ID	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.
Path cost	This is the path cost from this port to the root switch.
Cost to root	This is the path cost from the root port on this MSAP2000 AAMS to the root
switch.
Designated bridge	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.
Designated port	This is the port on the designated bridge that has the lowest path cost to reach
	the root bridge, consisting of bridge priority.
Poll Interval(s)	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.
Stop	Click Stop to halt STP statistic polling.
