Status. The following screen displays:
To view CST settings for an interface, click PORTS, LAGS, or All.
The following table describes the CST Status information displayed on the screen.
Table 16. CST Status Information.
Field Description
Interface Select a physical or port channel interface to configure. The port is
associated with the VLANs associated with the CST.
Port Role Each MST Bridge Port that is enabled is assigned a port role for each
spanning tree. The port role can be one of the following values: Root,
Designated,
Alternate, Backup, Master
, or Disabled.
Designated Root Root bridge for the CST. It is made up using the bridge priority and the base
MAC address of the bridge.
Designated Cost Displays cost of the port participating in the STP topology. Ports with a lower
cost are less likely to be blocked if STP detects loops.
Designated Bridge Bridge identifier of the bridge with the designated port. It is made up using
the bridge priority and the base MAC address of the bridge.
Designated Port Port identifier on the designated bridge that offers the lowest cost to the
LAN. It is made up from the port priority and the interface number of the port.
Edge Port Indicates whether the port is enabled as an edge port. Possible values are
Enabled and Disabled.
Point-to-point MAC Derived value of the point-to-point status.
