Role
— Displays the port role assigned by the STP algorithm to provide to STP paths. The possible field values are:
–
Designated
— The port or LAG through 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 or when a LAN has two or more connections connected to a shared segment.
–
Disabled
— 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.
