Usage Guidelines

The PV number is the total number of VLANs in which VBST has been enabled and into which all VBST-enabled interfaces are added. For example, if VBST is enabled on 10 interfaces and each interface is added into 100 VLANs in which VBST is enabled, the number of PVs occupied by all interfaces on the switch is 1000. If the number of occupied PVs exceeds the specifications, the CPU usage may be high. As a result, the switch cannot process tasks in a timely manner, protocol calculation is affected, and the switch cannot be managed by the NMS.

After VBST is enabled on a switch, you can run the display vbst port-vlan statistics command to check statistics on the PV number, including the number of occupied PVs and the maximum number of PVs supported by the switch.

Example

# Display statistics on the PV number after VBST is enabled on a switch.
