The following port-specific information is also displayed:

Hello The Hello Time parameter specifies, in seconds, how often the root bridge

transmits a configuration bridge protocol data unit (BPDU). Any bridge

that is not the root bridge uses the root bridge hello value.

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.

Table 29 RSTP/MSTP/PVRST Port Parameter Descriptions

Parameter Description

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

notation) and MAC address of the Designated Bridge.
