Displaying Stp Information - HP ProCurve 9304M Installation And Configuration Manual

Installation and Basic Configuration Guide

Displaying STP Information

You can display the following STP information:
• All the global and interface STP settings
• CPU utilization statistics
• Detailed STP information for each interface
• STP state information for a port-based VLAN
• STP state information for an individual interface
Displaying STP Information for an Entire Device
To display STP information for an entire device, use either of the following methods.
USING THE CLI
To display STP information, enter the following command at any level of the CLI:
HP9300# show span
VLAN 1 BPDU cam_index is 3 and the Master DMA Are(HEX)
STP instance owned by VLAN 1
Global STP (IEEE 802.1D) Parameters:

<lines for remaining ports excluded for brevity>
Syntax: show span [vlan <vlan-id>] | [pvst-mode] | [<num>] |
[detail [vlan <vlan-id> [ ethernet <portnum> ] | <num>]]
The vlan <vlan-id> parameter displays STP information for the specified port-based VLAN.
The pvst-mode parameter displays STP information for the device's Per VLAN Spanning Tree (PVST+)
compatibility configuration. See "PVST/PVST+ Compatibility" on page 8-75.
The <num> parameter displays only the entries after the number you specify. For example, on a device with three
port-based VLANs, if you enter 1, then information for the second and third VLANs is displayed, but information for
the first VLAN is not displayed. Information is displayed according to VLAN number, in ascending order. The
entry number is not the same as the VLAN number. For example, if you have port-based VLANs 1, 10, and 2024,
then the command output has three STP entries. To display information for VLANs 10 and 2024 only, enter show
span 1.
