DLP-A221 Provision E-Series Ethernet Ports for VLAN Membership
Step 3 To put a port in a VLAN:
a. Click the port and choose either Tagged or Untag.
b. If a port is a member of only one VLAN, choose Untag from the Port column in the VLAN’s row.
Choose -- for all the other VLAN rows in that Port column.
Note The VLAN with Untag selected can connect to the port, but other VLANs cannot access that
port.
c. Choose Tagged at all VLAN rows that need to be trunked. Choose Untag at VLAN rows that do not
need to be trunked, for example, the default VLAN.
Note Each Ethernet port must be attached to at least one untagged VLAN. A trunk port connects
multiple VLANs to an external device, such as a switch, which also supports trunking. A
trunk port must have tagging (IEEE 802.1Q) enabled for all the VLANs that connect to that
external device.
Step 4 After each port is in the appropriate VLAN, click Apply. Table 19-1 lists VLAN settings.
.
Note If Tagged is chosen, the attached external Ethernet devices must recognize IEEE 802.1Q
VLANs.
Note Both ports on an E1000-2/E1000-2-G card cannot be members of the same VLAN.
Step 5 Return to your originating procedure (NTP).
