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, enter the following command at any level of the CLI:
Syntax:
show span [vlan <vlan-id>] | [pvst-mode] | [<num>] |
[detail [vlan <vlan-id> [ethernet [<slotnum>/]<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 7-61.
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. See
“Displaying Detailed STP Information for Each Interface” on page 7-12.
