Description
Shows if STA is enabled on the switch and participated an STA
compliant network
The unique Bridge Identifier of the Bridge recorded as the Root
in the Configuration BPDUs transmitted by the Designated
Bridge for the segment to which the port is attached
The MAC address used by this bridge when it must be referred
to in a unique fashion. It is recommended that this be the
numerically smallest MAC address of all ports that belong to this
bridge. However it is only required to be unique
The port number of the port which offers the lowest cost path
from this bridge to the root bridge
The maximum age of Spanning Tree Protocol information
learned from the network on any port before it is discarded, in
units of a second. This is the actual value that this bridge is
currently using
The amount of time between the transmission of Configuration
bridge PDUs by this node on any port when it is the root of the
spanning tree or trying to become so, in units of a second. This
is the actual value that this bridge is currently using
This time value determines the interval length during which no
more than two Configuration bridge PDUs shall be transmitted
by this node, in units of a second
This time value, measured in units of a second, controls how
fast a port changes its spanning state when moving towards the
Forwarding state. The value determines how long the port stays
in each of the Listening and Learning states, which precede the
Forwarding state. This value is also used, when a topology
change has been detected and is underway, to age all dynamic
entries in the Forwarding Database
