Table 22 Spanning Tree Fields (continued)
Description Field
Set the port to recover from an error-disabled state. If recovery is not enabled, a port has to
be disabled and re-enabled for normal STP operation. The condition is also cleared by a
system reboot. BPDU Port Error Recovery
Time after which a port in the error-disabled state can be enabled. This value is also
applicable on the per-port BPDU Guard operations. BPDU Port Error Recovery
Timeout
Spanning Tree Port Settings
List of all physical ports and trunk interfaces configured on the system. Interface
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. Specify Auto or Path Cost
assign a value between 1-200000000. The default is Auto where the path cost is set using
the 802.1D recommended values.
Specify a value between 0-240 in increments of 16 to control the priority of ports with
identical port costs. The default is 128; 64 for trunk ports. Priority
Configure the port to act as a non-edge or edge port for Spanning Tree. The default is
non-edge. Admin Edge
Enable automatic edge port detection for the port. Auto Edge
When root guard is enabled on a port, that port cannot be selected as the root port even if
it receives superior STP BPDUs. The port is assigned an “alternate” port role and enters a Root Guard
blocking state if it receives superior STP BPDUs. Select this option to enable root guard for
the port. It is not selected by default.
With TCN guard enabled, a port does not propagate received topology change notifications
and topology changes to other ports. Select this option to enable TCN guard for the port.
It is not selected by default. TCN Guard
When an STP BPDU is received on a port that has BPDU protection enabled, the port disables
itself. Select this option to enable BPDU protection for the port. It is not selected by default. BPDU Protect
With BPDU filtering enabled, the port does not participate in Spanning Tree, and the port
remains in the forwarding state. Select this option to enable BPDU filtering for the port. It is
not selected by default. BPDU Filter
This parameter informs the switch whether the port connects to a single device or to a shared
medium with multiple devices. A point-to-point link has only one device at the far end. This Point-to-Point
can be automatically determined, or forced either true or false. Valid values are Forced True,
Forced False, and Auto. Default value is Forced True.
