USING THE CLI
To display the detailed STP information, enter the following command at any level of the CLI:
HP9300# show span detail
======================================================================
VLAN 1 - MULTIPLE SPANNING TREE (MSTP) ACTIVE
======================================================================
Bridge identifier
Active global timers - Hello: 0
Port 1/1 is FORWARDING
Port - Path cost: 19, Priority: 128, Root: 0x800000e052a9bb00
Designated - Bridge: 0x800000e052a9bb00, Interface: 1, Path cost: 0
Active Timers - None
BPDUs - Sent: 11, Received: 0
Port 1/2 is DISABLED
Port 1/3 is DISABLED
Port 1/4 is DISABLED
<lines for remaining ports excluded for brevity>
If a port is disabled, the only information shown by this command is "DISABLED". If a port is enabled, this display
shows the following information.
Syntax: show span detail [vlan <vlan-id> [ ethernet <portnum> ] | <num>]
The vlan <vlan-id> parameter specifies a VLAN.
The ethernet <portnum> parameter specifies an individual port within the VLAN (if specified).
The <num> parameter specifies the number of VLANs you want the CLI to skip before displaying detailed STP
information. For example, if the device has six VLANs configured (VLAN IDs 1, 2, 3, 99, 128, and 256) and you
enter the command show span detail 4, detailed STP information is displayed for VLANs 128 and 256 only.
NOTE: If the configuration includes VLAN groups, the show span detail command displays the master VLANs
of each group but not the member VLANs within the groups. However, the command does indicate that the VLAN
is a master VLAN. The show span detail vlan <vlan-id> command displays the information for the VLAN even if
it is a member VLAN. To list all the member VLANs within a VLAN group, enter the show vlan-group [<group­
id>] command.
The show span detail command shows the following information.

disabled."
