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).
