Max Age Specify the number of seconds from 6 seconds and 40 seconds until the BPDU information is
considered to be aged out or invalid. This value must be <= (FwdDelay-1)*2 and >= (He1)*2.
The default is 20 seconds.
Spanning Tree Interface Configuration
BPDU Port Error
Recovery 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 Timeout Specify the time from 30 seconds to 86400 seconds after which a port in the error-disabled state
can be enabled. This value is also applicable on the per-port BPDU Guard operations.
Spanning Tree Port Settings
Interface List of all physical ports and trunk interfaces configured on the system.
Path Cost 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 assign a value
between 1-200000000. The default is Auto where the path cost is set using the 802.1D recommended
values.
Priority 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.
Admin Edge Configure the port to act as a non-edge or edge port for Spanning Tree. The default is non-edge.
Auto Edge Enable automatic edge port detection for the port.
Root Guard 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 blocking state if it
receives superior STP BPDUs. Select this option to enable root guard for the port. It is not selected
by default.
TCN Guard 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.
BPDU Protect 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 Filter 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.
Point-to-Point 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 can be
automatically determined, or forced either true or false. Valid values are Forced True, Forced False,
and Auto. Default value is Forced True.
