9. From the STP
Status menu, select the option to enable or disable the spanning tree
administrative mode that is associated with the port or port channel.
The possible values are Enable and Disable. The default is Enable.
10. From the Fast
Link menu, select whether the specified port is an edge port within the CST.
The possible values are Enable, Disable, and Auto. The default value is
Auto, which
specifies that the switch waits three seconds (with no BPDUs received on the interface)
before placing the interface into the PortFast mode.
11. From the BPDU
Forwarding menu, configure BPDU forwarding.
The possible values are Enable and Disable. The default value is Disable. When BPDU
forwarding is enabled, the switch forwards the BPDU traf
fic arriving on this port when
STP is disabled on this port.
12. From the Auto
Edge menu, specify if the port is allowed to become an edge port if it does
not detect BPDUs for some time.
The option is Enable or Disable. The default value is Enable.
13. In the Path
Cost field, set the path cost to a new value for the specified port in the common
and internal spanning tree.
Specify a value in the range of 0 to 200000000. The default is 0. When the path cost is
set to 0, the value is updated with the external path cost from a received STP packet.
14. In the Priority
field, specify the priority for a particular port within the CST.
The port priority is set in multiples of 16. For example if you attempt to set the priority to
any value between 0 and 15, it is set to 0. If you try to set it to any value between 16 and
(2*16 – 1), it is set to 16, and so on. The range is 0 to 240.
The default is 128.
15. In the External
Port Path Cost field, set the external path cost to a new value for the
specified port in the spanning tree.
The value range is 0 to 200000000. The default is 0.
