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 the port forwards traffic while
■
learning MAC addresses.
Speed — Indicates the speed at which the port is operating.
■
Default Path Cost — Indicates that default path cost is enabled.
■
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. The field range is 1-200,000,000
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 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.
