Defining STP on Interfaces

–Root — Provides the lowest cost path to forward packets to root switch.

–Designated — Indicates that the port or LAG via which the designated switch is attached to the LAN.

–Alternate — Provides an alternate path to the root switch from the root interface.

–Backup — Provides a backup path to the designated port path toward the Spanning Tree leaves. Backup ports occur only when two ports are connected in a loop by a point-to-point link. Backup ports also occur when a LAN has two or more connections connected to a shared segment.

–Disabled — Indicates the port is not participating in the Spanning Tree.

•Speed — Indicates the speed at which the port is operating.

•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 value is between 0 -240. The priority value is determined in increments of 16.

•Designated Bridge ID — Indicates the bridge priority and the MAC Address of the designated bridge.

•Designated Port ID — Indicates the selected port D-Link 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 Block- ing state.

•LAG — Indicates the LAG to which the port belongs.
