priority
(port) The port priority parameter helps determine which bridge port becomes the
designated port/root port. In a network topology that has multiple bridge
ports with the same path-cost 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 which bridge port
becomes the designated port/root port. 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 can be Discard-
ing (DISC), Learning (LRN, or Forwarding (FWD).
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), Master (MAST).
Designated
Bridge
The Designated Bridge shows information about the bridge connected to
each port, if applicable. Information includes the priority (hex) and MAC
address of the Designated Bridge.
Designated Port The identifier of the port on the Designated Bridge to which this port is con-
nected.
Type Type of link connected to the port, and whether the port is an edge port. Link
type values are AUTO, P2P, or SHARED.
