Configuring protocol-based VLANs
Introduction to protocol-based VLAN
You use the protocol-based VLAN feature to assign packets to VLANs by their application type.
The protocol-based VLAN feature assigns inbound packets to different VLANs based on their protocol
type and encapsulation format. The protocols available for VLAN assignment include IP, IPX, and
AppleTalk (AT), and the encapsulation formats include Ethernet II, 802.3 raw, 802.2 LLC, and 802.2
SNAP.
A protocol template defines a protocol type and an encapsulation format. A protocol-based VLAN ID
and a protocol index, combined, can uniquely identify a protocol template. You can assign multiple
protocol templates to a protocol-based VLAN.
Protocol-based VLAN assignment is available only on hybrid ports, and a protocol template applies only
to untagged packets.
When an untagged packet arrives, a protocol-based VLAN assignment enabled hybrid port processes
the packet by using the following workflow:
If the protocol type and encapsulation format in the packet matches a protocol template, the packet
•
is tagged with the VLAN tag specific to the protocol template.
If no protocol template is matched, the packet is tagged with the PVID of the port.
•
The port processes a tagged packet as it processes tagged packets of a port-based VLAN.
If the port is in the same VLAN as the packet, it forwards the packet.
•
If not, the port drops the packet.
•
Configuration restrictions and guidelines
•
Do not configure both the dsap-id and ssap-id arguments in the protocol-vlan command as 0xe0 or
0xff when configuring the user-defined template for llc encapsulation. Otherwise, the encapsulation
format of the matching packets will be the same as that of the ipx llc or ipx raw packets,
respectively.
