Note that this command only applies to VLANs based on a single MAC address and IP subnet-based 

VLANs. If both MAC address-based VLANs and IP subnet-based VLANs are created on a port, MAC 

address-to-VLAN entries configured with the mask keyword specified are matched preferentially, and 

the left VLAN entries are matched as configured by the vlan precedence command. 

# Configure to match VLANs based on MAC addresses preferentially on GigabitEthernet 2/0/1.

interface-type interface-number1: Specifies an interface by its type and number. 

interface-type interface-number1 to interface-type interface-number2: Specifies an interface range. 

all: Displays information about protocol-based VLANs on all ports. 

Use the display protocol-vlan interface command to display information about protocol-based 

VLANs for the specified port(s). 

# Display protocol-based VLAN information on GigabitEthernet 2/0/1.

The sample output shows that untagged packets received on GigabitEthernet 2/0/1 will be tagged with 

VLAN ID 2 if they carry AppleTalk packets or with VLAN ID 3 if they carry IPv4 packets.
