Configure STP Settings

Create an Ethernet port profile.

Extreme Networks switches can use Spanning Tree Protocol (STP) to activate links with the lowest cost (highest bandwidth), establish backup links where possible, and prevent Layer 2 network loops, which can result in duplicate unicast frames and broadcast storms. Bridge Protocol Data Unit (BPDU) protection is a security feature designed to protect the active STP topology by preventing spoofed BPDU packets from entering the STP domain. BPDU protection is applied to edge ports connected to end-user devices that do not run STP. If STP BPDU packets are received on a protected port, this feature disables that port and alerts the network admin.

The BPDU Restrict feature disables the port as soon as a BPDU is received on the BPDU restrict port, blocking the loop. Specify a BPDU recovery timeout, enabling the port after the configured amount of time.

Note

BPDU Restrict can only be enabled when Edge port is also enabled.

Go to Configure > Common Objects > Policy
Toggle the switch to On to enable STP (Spanning Tree Protocol).
If you are enabling BPDU Protection, toggle the switch to On to enable Edge Port.
Select the Bridge Protocol Data Units (BPDU) Protection setting.
- Guard: Controls whether a port explicitly configured as Edge disables itself if it receives a BPDU. The port enters the error-disabled state and is removed from the active topology.
- Filter: Controls whether a port explicitly configured as Edge will transmit and receive BPDUs.
- Disable: Turn off BPDU Protection.
Select a Priority for STP from the drop-down list.
Toggle the switch to On to enable BPDU Restrict.
For BPDU recovery timeout, input a time between 60-600 seconds.

Note
The port is re-enabled automatically when time expires.

Continue configuring the Ethernet port.
