7 Assigning Ports
to VLANs
Initially all switch ports are non-mobile and 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. Switch ports are
either statically or dynamically assigned to VLANs.
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 “Statically Assigning Ports to VLANs” on page 7-4.)
• 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 12, “Configuring Static Link Aggregation,” and Chapter 13, “Configuring Dynamic Link
Aggregation.”)
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 determine VLAN assignment (see “Dynamically
Assigning Ports to VLANs” on page 7-4 for more information):
• Packet is tagged with a VLAN ID that matches the ID of another VLAN that has mobile tagging
enabled.
• Packet contents matches criteria defined in a VLAN rule.
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.
In This Chapter
This chapter describes how to statically assign ports to a new default VLAN and configure mobile ports
for dynamic assignment through the Command Line Interface (CLI). CLI commands are used in the
configuration examples; for more details about the syntax of commands, see the OmniSwitch CLI Refer-
ence Guide.
Configuration procedures described in this chapter include:
• Statically assigning ports to VLANs on page 7-4.
• Dynamically assigning ports to VLANs (port mobility) page 7-10.
• Configuring mobile port properties (including authentication) on page 7-16.
