Advanced Settings
Edge Port BPDU Filtering
- Controls whether a port is explicitly configured as Edge. It will transmit and
receive BPDUs.
Edge Port BPDU Guard
- Controls whether a port is explicitly configured as Edge. It will disable itself
upon reception of a BPDU. The port will enter the error-disabled state and will be removed from the
active topology.
Port Error Recovery
- Controls whether a port in the error-disabled state will be automatically enabled
after a certain time. If recovery is not enabled, ports have to be disabled and re-enabled for normal STP
operation. The condition is also cleared by a system reboot.
Port Error Recovery Timeout
- The time to pass before a port in the error-disabled state can be
enabled. Valid values are between 30 and 86400 seconds (24 hours).

Spanning Tree – Configuration - STP Port Config
This option allows you to inspect the current STP CIST port configurations and change them. It contains
settings for physical and aggregated ports.
Figure 8-2: STP Port Configuration
Port
- The switch port number of the logical STP port.
STP Enabled
- Controls whether STP is enabled on this switch port.
Path Cost
- Controls the path cost incurred by the port. The Auto setting will set the path cost as
appropriate by the physical link speed, using the 802.1D recommended values. Using the Specific
setting, a user-defined value can be entered. The path cost is used when establishing the active
topology of the network. Lower path cost ports are chosen as forwarding ports in favor of higher path
cost ports. Valid values are in the range 1 to 200000000.
Priority
- Controls the port priority. This can be used to control priority of ports having identical port
cost. (See above). Lower priority is better.
operEdge (state flag)
- Operational flag describing whether the port is connecting directly to edge
devices. (No Bridges attached). Transition to the forwarding state is faster for edge ports (having
operEdge true) than for other ports. The value of this flag is based on AdminEdge and AutoEdge fields.
This flag is displayed as Edge in Monitor
