Tagged Port Using Default VLAN 1 as its Port Native VLAN
The following figure shows an example of a PVST+ configuration that uses VLAN 1 as the untagged default VLAN and VLANs 2, 3, and 4 as tagged VLANs.
To implement this configuration, enter the following commands on your RUCKUS device.
device(config)# vlan-group 1 vlan 2 to 4 device(config-vlan-group-1)# tagged ethernet 1/1/1 device(config-vlan-group-1)# exit device(config)# interface ethernet 1/1/1 device(config-if-1/1/1)# pvst-mode
These commands configure a VLAN group containing VLANs 2, 3, and 4, add port 1/1/1 as a tagged port to the VLANs, and enable PVST+ support on the port. The implicit dual-mode feature allows the port to send and receive untagged frames for the default VLAN (VLAN 1 in this case) in addition to tagged frames for VLANs 2, 3, and 4. Enabling PVST+ support ensures that the port is ready to send and receive PVST+ BPDUs. If you do not manually enable PVST+ support, the support is not enabled until the port receives a PVST+ BPDU. The port can send and receive untagged frames for the default VLAN (VLAN 1 in this case) in addition to tagged frames for VLANs 2, 3, and 4.
The configuration leaves the default VLAN and the Port Native VLAN unchanged. The default VLAN is 1 and the Port Native VLAN also is 1.
Port 1/1/1 will process BPDUs as follows:
