Using VLANs to Increase the Number of Networks Available on the Appliance

VLANs appear as dynamic “Data Ports” labeled in the format of: “VLAN DDDD” where the “DDDD”
is the ID and is an integer up to 4 digits long (VLAN 2, or VLAN 4094 for example). AsyncOS supports
up to 30 VLANs.

A physical port does not need an IP address configured in order to be in a VLAN. The physical port on
which a VLAN is created can have an IP that will receive non-VLAN traffic, so you can have both VLAN
and non-VLAN traffic on the same interface.

VLANs can only be created on the Management and P1 data ports.

Configuring and Managing VLANs

You can create, edit and delete VLANs via the

etherconfig

command. Once created, a VLAN can be

configured via the

interfaceconfig

command in the CLI.

Example 1: Creating a New VLAN
