Example
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.
