Basic Network Configuration
VLANs
Virtual Local Area Networks (VLANs) are used to divide LAN traffic
into manageable broadcast domains. Using VLANs, the LAN can
be divided into smaller, logical networks, such as to segregate
wireless traffic from the rest of the LAN.
VLANs are created in two parts: first the network interface for the
VLAN must be defined on the switch, and then physical switch
ports must be added to the VLAN.
Creating a VLAN Interface
If you wish to allow routing between VLANs, you
must assign a routing interface to the VLAN, and pro-
vide it an IP address on the VLAN subnet. You can
skip this procedure if routing among VLANs is not
needed. (If no VLANs are configured in the startup
dialog script, then all ports are assigned to VLAN 1 by
default.)
Log in as the administrator and enter privileged mode.
Select a VLAN.
In this example, VLAN 2 will be used for wireless traffic:

Enter Configuration commands, one per line. End with CNTL/Z
