Step 2 Click the Provisioning > VLAN tabs (Figure9-22) .
Figure9-22 Configuring VLAN membership for individual Ethernet ports
Step 3 To put a port in a VLAN, click the port and choose either Tagged or Untag. Figure9-22 on page 9-25
shows Port 1 in the red VLAN and Port 2 through Port 12 in the default VLAN. Table 9-6 shows valid
port settings.
If a port is a member of only one VLAN, go to that VLAN’s row and choose Untag from the Port colum n.
Choose -- for all the other VLAN rows in that Port column. The VLAN with Untag selected can connect
to the port, but other VLANs cannot access that port.
If a port is a trunk port, it connects multiple VLANs to an external device, such as a switch, which also
supports trunking. A trunk port must have tagging (802.1Q) enabled for all the VLANs that connect to
that external device. Choose Tagged at all VLAN rows that need to be trunked. Choose Untag at one or
more VLAN rows in the trunk port’s column that do not need to be trunked, for example, the default
VLAN. Each Ethernet port must attached to at least one untagged VLAN.
Step 4 After each port is in the appropriate VLAN, click Apply.
