Configuring Protocol-based VLANs
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• When creating a protocol-based VLAN, only assign interfaces via this command. If you assign
interfaces using any of the other VLAN commands (such as the
vlan command), these
interfaces will admit traffic of any protocol type into the associated VLAN.
• When MAC-based, IP subnet-based, and protocol-based VLANs are supported concurrently,
priority is applied in this sequence, and then port-based VLANs last.
• 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 priority 0
Console(config-if)#
show protocol-vlan protocol-group
This command shows the frame and protocol type associated with protocol groups.
Syntax
show protocol-vlan protocol-group [group-id]
group-id - Group identifier for a protocol group. (Range: 1-2147483647)
Default Setting
All protocol groups are displayed.
Command Mode
Privileged Exec
Example
This shows protocol group 1 configured for IP over Ethernet:
Console#show protocol-vlan protocol-group
