To configure protocol-based VLANs, follow these steps:
1. First configure VLAN groups for the protocols you want to use
(page 3-55). 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 protocol-group command
(General Configuration mode).
3. Then map the protocol for each interface to the appropriate VLAN
using the protocol-vlan protocol-group command (Interface
Configuration mode).
protocol-vlan protocol-group (Configuring Groups)
This command creates a protocol group, or to add specific protocols to a
group. Use the no form to remove a protocol group.
