Index Displays the port index.
Admin MAC Enable Displays the status of the Admin MAC. Change the status using 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
mark indicates that the Oper MAC Enable status is active/enabled.
AutoEdge AutoEdge displays whether the port can automatically detect whether it is an 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 that 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 Displays the PortFast BPDU filter for the admin port. The Spanning Tree Protocol sends BPDUs from all ports.
BPDU Filter
Enabling the BPDU Filter ensures PortFast-enabled admin ports do not transmit or receive BPDUs.
OperPort PortFast Displays a PortFast BPDU filter for the oper port.
Bpdu Filter
Enabling the BPDU Filter feature ensures PortFast-enabled oper ports do not transmit or receive BPDUs.
AdminPort PortFast Displays the whether BPDU Guard is currently enabled for this port.
Bpdu Guard
When set for a bridge, all PortFast-enabled ports having the
bpdu-guard set to default shut down the port on receiving the BPDU. When this occurs, the BPDU is not processed.
OperPort PortFast Displays the whether BPDU Guard is currently enabled for this port.
Bpdu Guard
When the OperPort PortFast BPDU Guard feature is set for a bridge, all PortFast-enabled ports that have the
bpdu-guard set to default shut down the port on receiving a BPDU. When this occurs, the BPDU is not processed.
