Assigning Ports To Vlans; Changing The Default Vlan Assignment For A Port - Alcatel-Lucent OmniSwitch 9900 Series Network Configuration Manual

Configuring VLANs

Assigning Ports to VLANs

The OmniSwitch supports static assignment of physical switch ports to a VLAN. Once the assignment
occurs, a VLAN port association (VPA) is created and tracked by VLAN management software on each
switch. To view current VLAN port assignments in the switch configuration, use the
command.
Methods for statically assigning ports to VLANs include the following:
•
Using the vlan members untagged
ports. See "Changing the Default VLAN Assignment for a Port" on page
•
Using the vlan members tagged
method allows the switch to bridge traffic for multiple VLANs over one physical port connection. See
"Using 802.1Q Tagging" on page
•
Configuring ports as members of a link aggregate that is assigned to a configured default VLAN. (See
Chapter 8, "Configuring Static Link Aggregation,"

Changing the Default VLAN Assignment for a Port

Initially all switch ports are assigned to VLAN 1, which is also their configured default VLAN. When
additional VLANs are created on the switch, ports are assigned to the VLANs so that traffic from devices
connected to these ports is bridged within the VLAN domain.
To assign a switch port to a new default VLAN, use the
the following command assigns port 5 on slot 2 to VLAN 955:
-> vlan 955 members port 2/5 untagged
When the vlan members command is used, the port's default VLAN assignment is changed to the
specified VLAN. The previous default VLAN assignment for the port (for example, VLAN 1, VLAN 10
or VLAN 200) is dropped.
The vlan members command is also used to change the default VLAN assignment for an aggregate of
ports. The link aggregate control number is specified instead of a slot and port. For example, the following
command assigns link aggregate 10 to VLAN 755:
-> vlan 755 members linkagg 10 untagged
For more information about configuring an aggregate of ports, see
Aggregation."
Use the no form of the vlan members command to remove a default VPA. When this is done, VLAN 1 is
restored as the default VLAN for the port.
-> no vlan 955 members port 2/5
