15.14.5 Configuring Protocol-based VLANs Using the CLI
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 in use by the inbound packets.
Command Function Mode
Protocol-vlan protocol-
group
Create a protocol group, specifying the supported protocols GC
Protocol-vlan protocol-
group
Maps a protocol group to a VLAN IC
show protocol-vlan
protocol-group
Shows the configuration of protocol groups PE
show interfaces protocol-
vlan protocol-group
Shows the interfaces mapped to a protocol group and the
corresponding VLAN
PE
To configure protocol-based VLANs, follow these steps:
1. Configure VLAN groups for the protocols you want to use (see 15.14.2). Although not mandatory, you
should 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).
15.15 GVRP and Bridge Extension Commands
GARP VLAN Registration Protocol defines a way for switches to exchange VLAN to automatically register
VLAN members on interfaces across the network. This section describes how to enable GVRP for individual
interfaces and globally for the switch, as well as how to display default configuration settings for the Bridge
Extension MIB.

bridge-ext gvrp Enables GVRP globally for the switch GC
