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, configure the ECN330-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.
