CLI – This configures port 3 as an uplink and port 5 and 6 as downlinks.
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 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 (page 6). 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 Protocol VLAN Configuration page.
3. Then map the protocol for each interface to the appropriate VLAN using the
Protocol VLAN Port Configuration page.
Configuring Protocol Groups
Create a protocol group for one or more protocols.
