Protocol 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 being used by the inbound packets.
Command Usage
◆ To configure protocol-based VLANs, follow these steps:
1. First configure VLAN groups for the protocols you want to use (see
“Configuring VLAN Groups” on page 152). 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.
