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:

First configure VLAN groups for the protocols you want to use (page 4-174).
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.

Create a protocol group for each protocol you want to assign to a VLAN using
the protocol-vlan protocol-group command (General Configuration mode).

Then map the protocol for each interface to the appropriate VLAN using the
protocol-vlan protocol-group command (Interface Configuration mode).
