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 3-149). 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.
