6. Select whether to display physical interfaces, LAGs, or both by clicking one of the following
links above the table heading:
•1 (the unit ID of the switch). Only physical interfaces are displayed. This is the default
setting.
• LAG. Only LAGs are displayed.
• All. Both physical interfaces and LAGs are displayed.
7. Select one or more interfaces by taking one of the following actions:
• To configure a single interface, select the check box associated with the port, or type
the port number in the Go To Interface field and click the Go button.
• To configure multiple interfaces with the same settings, select the check box
associated with each interface.
• To configure all interfaces with the same settings, select the check box in the heading
row.
8. From the STP Status menu, select the option to enable or disable the spanning tree
administrative mode associated with the port or LAG.
The option is Enable or Disable. The default value is Enable.
9. From the Fast Link menu, select whether the specified port is an edge port within the CST.
The option is Enable or Disable. The default value is Disable.
10. From the BPDU Forwarding menu, configure BPDU forwarding.
The option is Enable or Disable. The default value is Disable. When BPDU forwarding is
enabled, the switch forwards the BPDU traffic arriving on the port when STP is disabled
on the port.
11. 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.
12. 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 from 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 an incoming STP packet.
13. 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 value is 128.
14. 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.
