Internal Root Cost: Displays the path cost to the designated
root for the selected MST instance.
Designated Bridge: Displays the Bridge Identifier of the
bridge for the Designated Port. It is made
up using the bridge priority and the base
MAC address of the bridge.
Internal Port Cost: This parameter is set to represent the rel-
ative cost of forwarding packets to spec-
ified ports when an interface is selected
within an STP instance. Selecting this
parameter with a value in the range of 1
to 200000000 will set the quickest route
when a loop occurs. A lower internal cost
represents a quicker transmission. Select-
ing 0 (zero) for this parameter will set the
quickest optimal route automatically for
an interface.
Port Role: Each MST bridge port that is enabled is
assigned a Port Role for each spanning
tree. The Port Role is one of the following
values: Root, Designated, Alternate, Back-
up, Master, or Disabled.
Port State: Displays the state of the selected port.
Edge Port Oper:
Displays the operating Edge Port state.
P2P MAC Conf: Displays the P2P MAC state.
P2P MAC Oper: Displays the operating P2P MAC state.
Port Role: Displays the port role. Shows each MST
Bridge Port that is assigned a port role for
each spanning tree.
Port State: Displays the state of the selected port.
Port State: Indicates the current STP state of a port. If en-
abled, the Port State determines what forwarding
action is taken regarding traffic. The possible port
states are:
• Disabled: STP is disabled on the port. The port
forwards traffic while learning MAC addresses.
• Blocking: The port is blocked and cannot be
used to forward traffic or learn MAC addresses.
• Listening: The port is in listening mode. The
port cannot forward traffic or learn MAC addresses
in this state.
• Learning: The port is in learning mode. The
port cannot forward traffic. However, it can learn
new MAC addresses.
• Forwarding: The port is in forwarding mode.
The port can forward traffic and learn new MAC
addresses in this state.
