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.
Note
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.
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.
Caution
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.
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.
