Auto Edge, Root Guard, TCN Guard, Port Mode

Page 120 highlights

Web Management User Guide 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 Auto Calculated Port Path Cost Hello Timer Auto Calculated External Port Path Cost BPDU Guard Effect Port Forwarding State Description 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. Displays the value of the parameter for the CST. 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. Display the BPDU Guard Effect, it disables the edge ports that receive BPDU packets. The possible values are Enable or Disable. The Forwarding State of this port. 120

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.
