– Port State – Displays the current STP state of a port. If enabled, the port state determines
what forwarding action is taken on traffic. Possible port states are:
– Forwarding – Indicates that STP is enabled on the port, and the port is forwarding
packets based on the STP topology.
– Disabled – Indicates that STP is currently disabled on the port. The port forwards
traffic while learning MAC addresses.
– Blocking – Indicates that the port is currently blocked and cannot forward traffic or
learn MAC addresses. Blocking is displayed when STP is enabled.
– Speed – Indicates the speed at which the port is operating.
– Path Cost – Specifies the method used to assign default path cost to STP ports. The
possible field values are:
– Short – Specifies 1 through 65,535 range for port path cost. This is the default value.
– Long – Specifies 1 through 200,000,000 range for port path cost. The default path cost
assigned to an interface varies according to the selected method (Hello Time, Max
Age, or Forward Delay).
– Priority – Specifies the bridge priority value. When switches or bridges are running STP,
each is assigned a priority. After exchanging Bridge Protocol Data Units
(BPDUs), the
device with the lowest priority value becomes the Root Bridge. The default value is
32768. The port priority value is provided in increments of 4096.

Tree Page. The Global LAGs section displays the STP information for Link Aggregated Groups.
