Configuring standard STP parameters
6
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 <portnum> parameter specifies an individual port within the VLAN (if specified).
. The <portnum> parameter is a valid port number.
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.

NOTE: If STP is disabled on a VLAN, the command displays the following
message instead: “Spanning-tree of port-vlan <vlan-id> is disabled.”
Bridge identifier The STP identity of this device.
