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
(
). 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
command (Global
Configuration mode).
3.
Then map the protocol for each interface to the appropriate VLAN using
the
command (Interface Configuration
mode).
