Syntax: show span [vlan <vlan-id>] | [pvst-mode] | [<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 6-37.
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.
The show span command shows the following information.

The port-based VLAN that contains this spanning tree (instance of
STP). VLAN 1 is the default VLAN. If you have not configured port-
based VLANs on this device, all STP information is for VLAN 1.
The ID assigned by STP to the root bridge for this spanning tree.
The cumulative cost from this bridge to the root bridge. If this device
is the root bridge, then the root cost is 0.
