Defining Vlan Port Assignments; Changing The Default Vlan Assignment For A Port - Alcatel-Lucent OmniSwitch 6850-48 Network Configuration Manual

Defining VLAN Port Assignments

Defining VLAN Port Assignments
Alcatel-Lucent 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 assignments in the switch configuration, use the
Methods for statically assigning ports to VLANs include the following:
•
Using the vlan port default
(fixed) and mobile ports. (See
•
Using the vlan 802.1q
the switch to bridge traffic for multiple VLANs over one physical port connection. (See
"Configuring 802.1Q.")
•
Configuring ports as members of a link aggregate that is assigned to a configured default VLAN. (See
Chapter 22, "Configuring Static Link Aggregation,"
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 6, "Assigning Ports to VLANs,"
•
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
•
Packet contents matches criteria defined in a VLAN rule. (See
tion" on page 4-9

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
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
Aggregation," and Chapter 23, "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.
