2.4.3 Functional Differences in Product Categories

There are a number of different options that are available to manage VLANs in the newer devices, however the

Basics for creating and configuring a VLAN - are simplified into a small subset of commands that are described

below. For more sophisticated users, access to the BRIDGE VLAN commands can provide additional flexibility.

Note 1:

To create a primary IP interface and connect it to a VLAN, the following steps must be performed.

• Create a VLAN using the VLAN ADD VID command

• Add ports to the VLAN using the VLAN ADD PORT command

• Add the VLAN to the Ethernet transports list using the ETHERNET ADD TRANSPORT command. This

command instructs the system that a new (virtual) transport device has been added to the system.

• Create an IP interface with the IP ADD INTERFACE command. This command constructs a new IP

interface with the specified IP address and net mask but doesn't bind the IP interface to any port.

• Bind the IP interface to the VLAN using the IP ATTACH TRANSPORT command.

***** It is not necessary to add the VLAN to the CPU port - when the VLAN is attached to the bridge,

it is automatically added to the CPU port.

Note 2:

To create a primary IP interface and connect it to a VLAN, the following steps must be performed.

• Create a VLAN using the VLAN CREATE command - the VLAN is automatically created on the Bridge.

• Add switch ports to the VLAN using the VLAN ADD command

• Create an IP interface with the IP ADD INTERFACE command. This command constructs a new IP

interface with the specified IP address and net mask but doesn't bind the IP interface to any port.

• Bind the IP interface to the VLAN using the IP ATTACH command.

***** If it is desired that the CPU recieve traffic in a particular VLAN, it is necessary to add the VLAN to

the CPU port - in the tagged mode - using the VLAN ADD command.
