Configuring VLANs Defining VLAN Port Assignments

Defining VLAN Port Assignments

Alcatel switches support static and dynamic assignment of physical switch ports to a VLAN. Regardless

of how a port is assigned 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 assign-

ments in the switch configuration, use the show vlan port command.

Methods for statically assigning ports to VLANs include the following:

• Using the vlan port default command to define a new configured default VLAN for both non-mobile

(fixed) and mobile ports. (See “Changing the Default VLAN Assignment for a Port” on page 5-7.)

• Using the vlan 802.1q command to define tagged VLANs for non-mobile ports. This method allows

the switch to bridge traffic for multiple VLANs over one physical port connection. (See Chapter 11,

“Configuring 802.1Q.”)

• Configuring ports as members of a link aggregate that is assigned to a configured default VLAN. (See

Chapter 13, “Configuring Static Link Aggregation,” and Chapter 14, “Configuring Dynamic Link

Aggregation,” for more information.)

Dynamic assignment applies only to mobile ports. When traffic is received on a mobile port, the packets

are classified using one of the following methods to automatically determine VLAN assignment (see

Chapter 7, “Assigning Ports to VLANs,” for more information):

• Packet is tagged with a VLAN ID that matches the ID of another VLAN that has mobile tagging

enabled. (See “Enabling/Disabling VLAN Mobile Tag Classification” on page 5-9.)

• Packet contents matches criteria defined in a VLAN rule. (See “Configuring VLAN Rule Classifica-

tion” on page 5-8 and Chapter 9, “Defining VLAN Rules.”)

Changing the Default VLAN Assignment for a Port

To assign a switch port to a new default VLAN, enter vlan followed by an existing VLAN ID number,

port default, then the slot/port designation. For example, the following command assigns port 5 on slot 2

to VLAN 955:

-> vlan 955 port default 2/5

All ports initially belong to default VLAN 1. When the vlan port default command is used, the port’s

default VLAN assignment is changed to the specified VLAN. In the above example, VLAN 955 is now

the default VLAN for port 5 on slot 2 and this port is no longer associated with VLAN 1.

The vlan port default 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 follow-

ing command assigns link aggregate 10 to VLAN 755:

-> vlan 755 port default 10

For more information about configuring an aggregate of ports, see Chapter 13, “Configuring Static Link

Aggregation,” and Chapter 14, “Configuring Dynamic Link Aggregation.”

Use the no form of the vlan port default command to remove a default VPA. When this is done, VLAN 1

is restored as the port’s default VLAN.

-> vlan 955 no port default 2/5
