Syntax: show span pvst-mode
This command displays the following information.
Configuration examples
The examples use two common configurations:
• Untagged IEEE 802.1Q BPDUs on VLAN 1 and tagged PVST+ BPDUs on other VLANs
• Tagged IEEE 802.1Q BPDUs on VLAN 1 and untagged BPDUs on another VLAN
Tagged port using default VLAN 1 as its port native VLAN
In Figure 32, a PVST+ configuration uses VLAN 1 as the untagged default VLAN and VLANs 2, 3,
and 4 as tagged VLANs.
FIGURE 32 Default VLAN 1 for untagged BPDUs
To implement this configuration, enter the following commands on the device.
BigIron RX(config)# vlan-group 1 vlan 2 to 4
BigIron RX(config-vlan-group-1)# tagged ethernet 1/1
BigIron RX(config-vlan-group-1)# exit
BigIron RX(config)# interface ethernet 1/1
BigIron RX(config-if-e10000-1/1)# pvst-mode
