On the Device Physical View select a port, or use Ctrl-click to select more than one port.
Right-click the port or group of ports.
From the drop-down menu, click Edit.
On the work area, click the STP BPDU-Filtering tab.
If you selected a group of ports on the Device Physical View, perform the following actions for each port in the list:
To select a port to edit, click the cell in the rcPortIndex column.
In the port row, double-click the cell in the Admin Enabled column.
Click the arrow to reveal the list.
Select a value from the list—true to enable STP BPDU filtering for the port, or false to disable STP BPDU filtering for the port.
In the port row, double-click the cell in the Timeout column.
Type a value in the dialog box.
If you selected a single port on the Device Physical View:

The following table outlines the parameters of the STP BPDU-Filtering tab.
Variable | Value |
---|---|
rcPortIndex | Indicates the switch and port number. |
AdminEnabled | Enables and disables BPDU filtering on the port. |
OperEnabled | Indicates the current operational status of BPDU filtering on the port: true (enabled) or false (disabled). |
Timeout | When BPDU filtering is enabled, this parameter indicates the time, in 1/100 seconds, during which the port remains disabled after it receives a BPDU. The port timer is disabled if this value is set to 0. The default value is 12000 (120 seconds). |
TimerCount | Displays the time remaining for the port to stay in the disabled state after receiving a BPDU. |
