2. Select the Port tab
The Port tab displays the following information (ensure you scroll to the right to view the numerous port
variables described):
Index Displays the port index.
Admin MAC Enable Displays the status of the Admin MAC. Change the status using the
Edit button. A green check mark indicates the Admin MAC Enable
status is active/enabled.
Oper MAC Enable This field displays the status of the Oper MAC Enable. You can
change the status using the Edit button. A green check mark
indicates the Oper MAC Enable status is active/enabled.
AutoEdge Displays whether the port is configured as an operational edge
port.
Designated Bridge Displays the ID of the bridge sent the best BPDU received on this
port.
Guard Root Displays whether the listed port index enforces root bridge
placement. The guard root ensures the port is a designated port.
Typically, each guard root port is a designated port, unless two or
more ports (within the root bridge) are connected together. If the
bridge receives superior (BPDUs) on a guard root-enabled port, the
guard root moves the port to a root-inconsistent STP state. This
state is equivalent to a listening state. No data is forwarded across
the port. Thus, the guard root enforces the root bridge position.
AdminPort PortFast
BPDU Filter
Displays the portfast BPDU filter for the admin port. The Spanning
Tree Protocol sends BPDUs from all ports.
Enabling the BPDU Filter ensures PortFastenabled admin ports do
not transmit or receive BPDUs.
