Hello
You specify the trunk number in the CLI command. The individual ports are not valid for the command if they are trunk members.
HP-2920-48G(config)# sh tr
Port | Name Type | Group Type
------ + -------------------------------- ---------- + ----- --------
10 | 100/1000T | Trk1 Trunk
11 | 100/1000T | Trk1 Trunk
HP-2920-48G(config)# spanning-tree 10 bpdu-filter
Module not present for port or invalid port: 10
HP-2920-48G(config)# spanning-tree trk1 bpd?
bpdu-filter
bpdu-protection

Subject: BPDU Filtering on Trunk
Hi
We have a 8320 Core with 2 Sites (1 & 2). Both Sites have a VSX cluster of 2 8320s and MCLAG between the Sites. We do run a number of distribution and access switches on both sites supporting various inhouse/3rd party systems, some of them using their own L2 switches. Some of these systems run between the sites.
We want to keep the 8320 Core Spanning Tree free but run STP on both Sites. Distribution switches on each site Connect to their 8320 VSX clusters over Trunk (Dist side) and MCLAG (8302 side).
As I understand I can configure BPDU Filtering on the Distribution switches facing the VSX Core to omit these interfaces from the STP. What I cannot find in documentation is how to configurte it on a Trunk.
- spanning-tree <port-list> bpdu-filter
or
- spanning-tree Trk1 bpdu-filter
