Syntax: show span [vlan <vlan-id>] | [pvst-mode] | [<num>] | [detail [vlan <vlan-id> [ethernet
The vlan <vlan-id> parameter displays STP information for the specified port-based VLAN.
The pvst-mode parameter displays STP information for the device Per VLAN Spanning Tree (PVST+)
compatibility configuration. Refer to
Specify the <port> variable in the following formats:
•
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 detail parameter and its additional optional parameters display detailed information for
individual ports. Refer to
The show span command shows the following information.
