Field Description
200,000,000. The default value is automatically set cost, according to its speed. Default port
cost: 10Mbps port = 2000000, 100Mbps port = 200000. Gigabit port = 20000, Port-channel =
20000.
Priority
Defines the interface priority for the specified instance. The default value is 128.
Status
Indicates whether the port is enabled for the specific instance. The possible field values are:
Forwarding — Enables the port for the specific instance.
Listening - Processes BPDUs received from the system module
Learning – Incorporates station location into its address database
Blocking - Discards frames received from the attached segment and frames switched from
another port for forwarding
Disabled — Disables the port for the specific instance.
Ind
icates the port role assigned by the STP algorithm to provide to STP paths. The possible
field values are:
Enabled — Enables the port for the specific instance.
Root — Provides the lowest cost path to forward packets to the root device.
Designated — Indicates the port or LAG through which the designated device is attached
to the LAN.
Alternate — Provides an alternate path to the root device 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 — Indicates the port is not participating in the Spanning Tree.
