4.5.8 Protocol VLAN Group Setting
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 LRP Managed 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:
First configure VLAN groups for the protocols you want to use. Although not mandatory, we suggest configuring a
1.
separate VLAN for each major protocol running on your network. Do not add port members at this time.
Create a protocol group for each of the protocols you want to assign to a VLAN using the Protocol VLAN Configuration
2.
page.
3.
Then map the protocol for each interface to the appropriate VLAN using the Protocol VLAN Port Configuration page.
This page allows you to configure protocol-based VLAN Group Setting. The portocol-based VLAN screens in
