Configuring Protocol-based VLANs

The network devices required to support multiple protocols cannot be easily grouped into a
common VLAN. This may require non-standard devices to pass traffic between different VLANs in
order to encompass all the devices participating in a specific protocol. This kind of configuration
deprives users of the basic benefits of VLANs, including security and easy accessibility.

To avoid these problems, you can configure this switch with protocol-based VLANs that divide the
physical network into logical VLAN groups for each required protocol. When a frame is received at a
port, its VLAN membership can then be determined based on the protocol type in use by the
inbound packets.

To configure protocol-based VLANs, follow these steps:

1. First configure VLAN groups for the protocols you want to use (

page 379

). Although not

mandatory, we suggest configuring a separate VLAN for each major protocol running on your
network. Do not add port members at this time.

2. Create a protocol group for each of the protocols you want to assign to a VLAN using the

protocol-vlan protocol-group

command (Global Configuration mode).

3. Then map the protocol for each interface to the appropriate VLAN using the

protocol-vlan

protocol-group

command (Interface Configuration mode).
