Command Usage
To configure protocol-based VLANs, follow these steps:
1. First configure VLAN groups for the protocols you want to use (page 3-140).
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.
