Dual-mode VLAN ports
To enable the dual-mode feature on port 2/11 in Figure 93,enter the following commands.
Brocade(config)# vlan 20
Brocade(config-vlan-20)# tagged ethernet 2/11
Brocade(config-vlan-20)# tagged ethernet 2/9
Brocade(config-vlan-20)# interface ethernet 2/11
Brocade(config-if-e1000-2/11)# dual-mode
Brocade(config-if-e1000-2/11)# exit
Syntax: [no] dual-mode
You can configure a dual-mode port to transmit traffic for a specified VLAN (other than the
DEFAULT-VLAN) as untagged, while transmitting traffic for other VLANs as tagged. Figure 94
illustrates this enhancement.
