Configuration examples

The examples use two common configurations:
•
•
Tagged port using default VLAN 1 as its port native VLAN
In Figure
and 4 as tagged VLANs.
FIGURE 32
To implement this configuration, enter the following commands on the RX.
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
These commands configure a VLAN group containing VLANs 2, 3, and 4, add port 1/1 as a tagged
port to the VLANs, and enable the dual-mode feature and PVST+ support on the port. The
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 the 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 configuration leaves the default VLAN and the port's native VLAN unchanged. The default
VLAN is 1 and the port's Port Native VLAN also is 1. The dual-mode feature supports untagged
frames on the default VLAN only. Thus, port 1/1 can send and receive untagged BPDUs for VLAN 1
and can send and receive tagged BPDUs for the other VLANs.

NOTE: The command lists information only for the ports on which
PVST+ support is enabled.
The method by which PVST+ support was enabled on the port. The
method can be one of the following:
•
Set by configuration – You enabled the support.
•
Set by auto-detect – The support was enabled automatically when
the port received a PVST+ BPDU.
