Displaying PVST Information
To display PVST information, use the following CLI method.
USING THE CLI
To display PVST information for ports on an HP device, enter the following command at any level of the CLI:
HP 9304M or HP 9308M(config)# show span pvst-mode
VLAN Port PVST PVST
ID Num. Cfg. On(by cfg. or detect)
200 10 0 1
200 11 1 1
This example shows that for VLAN 200, PVST support is statically enabled on port 11. PVST is not statically
enabled on Port 10, but because port 10 received an incoming PVST BPDU on its interface, the port converted to
using PVST mode.
Syntax: show span pvst-mode
The show span pvst-mode command displays the following information.
