Protocol-based VLANs are most often used in situations where network segments contain hosts running multiple protocols such as ARP, IP, and IPX. You can associate any protocol-identified by the packet's Ethertype field (1536 to 65535)-with a VLAN ID. To identify a protocol with a VLAN, you first create a protocol group and assign a protocol group ID number. You can also assign a name to the protocol group. Then, you add the protocol's Ethertype to the protocol group. Or, you can add a protocol to an existing protocol group. CLI Example The following commands create a vlan protocol group, name the group, add a protocol to it, and associate the protocol group with a port: console(config)#vlan protocol group 1 console(config)#vlan protocol group name 1 usergroup console(config)#vlan protocol group add protocol 2 ethertype 0x0800 The following command associates the protocol group with a port 1/g1: console(config)#interface ethernet 1/g1 console(config-if-1/g1)#protocol vlan group 1 To associate the protocol group with all ports, use the following command: console(config)#protocol vlan group all 1 30 Switching Configuration

Protocol-Based VLANs
The software supports protocol-based VLANs, where only packets are bridged based on their layer 3
protocol. Protocol-based VLANs are most often used in situations where network segments contain hosts
running multiple protocols such as ARP, IP, and IPX. You can associate any protocol—identified by the
packet’s Ethertype field (1536 to 65535)—with a VLAN ID.
To identify a protocol with a VLAN, you first create a protocol group and assign a protocol group ID
number. You can also assign a name to the protocol group. Then, you add the protocol’s Ethertype to the
protocol group. Or, you can add a protocol to an existing protocol group.
CLI Example
The following commands create a vlan protocol group, name the group, add a protocol to it, and
associate the protocol group with a port:
console(config)#vlan protocol group 1
console(config)#vlan protocol group name 1 usergroup
console(config)#vlan protocol group add protocol 2 ethertype 0x0800
The following command associates the protocol group with a port 1/g1:
console(config)#interface ethernet 1/g1
console(config-if-1/g1)#protocol vlan group 1
To associate the protocol group with all ports, use the following command:
console(config)#protocol vlan group all 1
