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 — 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
■
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.
— Indicates if a point-to-point link is currently
