HP 3400CL-24G Configuring STP Bpdu Protection, ProCurveconfig# spanning-tree 1-10 bpdu protection

Enhancements

Release M.10.17 Enhancements

STP — Spanning Tree Protocol, part of the original IEEE 802.1D specification. The 2004 edition completely deprecates STP. Both RSTP and MSTP have fallback modes to handle STP.

SNMP — Simple Network Management Protocol, used to remotely manage network devices.

N o t e

The switches covered in these Release Notes, use the IEEE 802.1s Multiple Spanning Tree Protocol (MSTP) standard. Under standard settings, your MSTP-configured switch interoperates effectively with both STP (IEEE 802.1D) and RSTP (IEEE 802.1w) spanning-tree devices. For more information, refer to the chapter entitled Multiple Instance Spanning-Tree Operation in the Advanced Traffic Management Guide for your switch.

Configuring STP BPDU Protection

The following commands allow you to configure BPDU protection via the CLI.

Syntax: [no] spanning-tree <port-list> bpdu protection

Enables/disables the BPDU protection feature on a port

Syntax: [no] spanning-tree trap errant bpdu

Enables/disables the sending of errant BPDU traps.

For example, to configure BPDU protection on ports 1 to 10, enter:

ProCurve(config)# spanning-tree 1-10 bpdu protection

When BPDU protection is enabled, the following steps are set in process:

1.When an STP BPDU packet is received, STP treats it as an unauthorized transmission attempt and shuts down the port that the BPDU came in on.

2.An event message is logged and an SNMP notification trap is generated.

3.The port remains disabled until re-enabled manually by a network administrator.

C a u t i o n

This command should only be used to guard edge ports that are not expected to participate in STP operations. Once BPDU protection is enabled, it will disable the port as soon as any BPDU packet is received on that interface.
