Protocol-Based VLAN Configuration 101
I. Creating a VLAN protocol type
Table 85 lists the operations to create a VLAN protocol type.
As the mode llc dsap ff ssap ff and ipx raw keywords result in the same packet
format, the ipx raw keyword takes precedence over the mode llc dsap ff ssap ff
keyword, and the system stops matching the subsequent keywords if the ipx raw
keyword does not match, executing the protocol-vlan command in the form of mode
llc dsap ff ssap ff does not take effect.
If you set the dsap-id and ssap-id arguments to AA or FF, the packet encapsulation
type will be snap instead of llc.
Associating a port with a protocol-based VLAN
Use the following commands to associate ports with protocol VLANs.
Before associate a port with a protocol-based VLAN, make sure the port is a hybrid
port, and the port belongs to the protocol-based VLAN.
