Interface Configuration (Ethernet, Port Channel)
Usage Guidelines
When creating a protocol-based VLAN, only assign interfaces via this command. If you assign interfaces
using any of the other VLAN commands (see 15.14.2), these interfaces will admit traffic of any protocol type
into the associated VLAN.
When a frame enters a port that has been assigned to a protocol VLAN, it is processed in the following
manner:
• If the frame is tagged, it will be processed according to the standard rules applied to tagged frames.
• If the frame is untagged and the protocol type matches, the frame is forwarded to the appropriate VLAN.
• If the frame is untagged but the protocol type does not match, the frame is forwarded to the default
VLAN for this interface.
Example
The following example maps the traffic entering Port 1, which matches the protocol type specified in protocol
group 1 to VLAN 2.
Console(config)#interface ethernet 1/1
Console(config-if)#protocol-vlan protocol-group 1 vlan 2
Console(config-if)#
