MaxAge The maximum age parameter specifies, in seconds, the maximum time the
bridge waits without receiving a configuration bridge protocol data unit
before it reconfigures the STP network.
FwdDel The Forward Delay parameter specifies, in seconds, the amount of time
that a bridge port has to wait before it changes from listening to learning
and from learning state to forwarding state.
Aging The aging time parameter specifies, in seconds, the amount of time the
bridge waits without receiving a packet from a station before removing
the station from the Forwarding Database.
Prio
(port) The port priority parameter helps determine which bridge port becomes
the designated port. In a network topology that has multiple bridge ports
connected to a single segment, the port with the lowest port priority
becomes the designated port for the segment.
Cost The port path cost parameter is used to help determine the designated port
for a segment. Generally speaking, the faster the port, the lower the path
cost. A setting of 0 indicates that the cost will be set to the appropriate
default after the link speed has been auto negotiated.
State The State field shows the current state of the port. The State field in RSTP
or MSTP mode can be one of the following: Discarding (DISC), Learning
(LRN), Forwarding (FWD), or Disabled (DSB).
Role The Role field shows the current role of this port in the Spanning Tree.
The port role can be one of the following: Designated (DESG), Root
(ROOT), Alternate (ALTN), Backup (BKUP), Disabled (DSB), Master
(MAST).
Designated Bridge The Designated Bridge shows information about the bridge connected to
each port, if applicable. Information includes the priority (in hexadecimal
format) and MAC address of the Designated Bridge.
Designated Port The port ID of the port on the Designated Bridge to which this port is
connected.
Type Type of link connected to the port, and whether the port is an edge port.
Link type values are AUTO, P2P, or SHARED.
