Configuring Protocol-based VLANs
– 1154 –
To configure protocol-based VLANs, follow these steps:
1. First configure VLAN groups for the protocols you want to use
(page 1132). 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 (Global
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.
