■ Path Cost — Indicates the port contribution to the root path cost. The
path cost is adjusted to a higher or lower value, and is used to forward
traffic when a path is re-routed.
■ Priority — Indicates the priority value of the port. The priority value
influences the port choice when a bridge has two ports connected in a
loop. The priority range is between 0-240. The priority value is
determined in increments of 16.
■ RSTP Link Type — Indicates whether a Point-to-Point link is
established, or if the device is permitted to establish a Point-to-Point
link. The possible field values are:
■
Auto — Enables the device to establish automatically
point-to-point link.
■
Point to Point — Indicates if a point-to-point link is currently
established on the port. Ports set to Full Duplex modes are
considered Point-to-Point port links.
■
Shared — Enables the device to establish a shared link.
■
Designated Bridge ID — Indicates the bridge priority and the MAC
Address of the designated bridge.
■ Designated Port ID — Indicates the selected port priority and
interface.
■ Designated Cost — Indicates the cost of the port participating in the
STP topology. Ports with a lower cost are less likely to be blocked if
STP detects loops.
■
Forward Transitions — Indicates the number of times the port has
changed from Forwarding state to Blocking state.
