4. Use Port Path Cost to set the Path Cost to a new value for the specified port in the
common and internal spanning tree. It takes a value in the range of 1 to 200000000.
5. Use External Port Path Cost to set the External Path Cost to a new value for the specified
port in the spanning tree. It takes a value in the range of 1 to 200000000.
6. Use BPDU Filter to configure the BPDU Filter, which filters the BPDU traffic on this port
when STP is enabled on this port. The possible values are Enable or Disable.
7. Use BPDU Flood to configure the BPDU Flood, which floods the BPDU traffic arriving on
this port when STP is disabled on this port. The possible values are Enable or Disable.
8. Use Auto Edge to configure the auto edge mode of a port, which allows the port to become
an edge port if it does not see BPDUs for some duration. The possible values are Enable or
Disable.
9. Use Root Guard to configure the root guard mode, which sets a port to discard any superior
information received by the port and thus protect against root of the device from changing.
The port gets put into discarding state and does not forward any packets. The possible
values are Enable or Disable.
10. Use Loop Guard to configure the loop guard on the port to protect layer 2 forwarding loops.
If loop guard is enabled, the port moves into the STP loop inconsistent blocking state instead
of the listening/learning/forwarding state.
11. Use TCN Guard to configure the TCN guard for a port restricting the port from propagating
any topology change information received through that port. The possible values are Enable
or Disable.
12. Use Port Mode to enable/disable Spanning Tree Protocol Administrative Mode associated
with the port or port channel. The possible values are Enable or Disable.
Field Description
Auto Calculated Port Path Cost Displays whether the path cost is automatically calculated (Enabled)
or not (Disabled). Path cost will be calculated based on the link speed
of the port if the configured value for Port Path Cost is zero.
Hello Timer Displays the value of the parameter for the CST.
Auto Calculated External Port Path
Cost
Displays whether the external path cost is automatically calculated
(Enabled) or not (Disabled). External Path cost will be calculated
based on the link speed of the port if the configured value for External
Port Path Cost is zero.
BPDU Guard Effect Display the BPDU Guard Effect, it disables the edge ports that
receive BPDU packets. The possible values are Enable or Disable.
Port Forwarding State The Forwarding State of this port.
