2-6z Because the IP protocol is closely associated with the ARP protocol, you are recommended toconfigure the ARP protocol type when configuring the IP protocol type and associate the twoprotocol types with the same port to avoid that ARP packets and IP packets are not assigned to thesame VLAN, which will cause IP address resolution failure.z If you specify some special values for both the dsap-id and ssap-id arguments when configuringthe user-defined template for IIc encapsulation, the matching packets will take the sameencapsulation format as some standard type of packets. For example, when both dsap-id andssap-id have a value of 0xFF, the encapsulation format will be the same as that of ipx raw packets;if they both have a value of 0xE0, the packet encapsulation format will be the same as that of ipx llcpackets; if they both have a value of 0xAA, the packet encapsulation format will be the same as thatof snap packets. To prevent two commands from processing packets of the same protocol type indifferent ways, the system does not allow you to set both the dsap-id and ssap-id arguments to0xFF, 0xE0, or 0xAA.z When you use the mode keyword to configure a user-defined protocol template, if you set theetype-id argument for ethernetii or snap packets to 0x0800, 0x809B, or 0x8137, the matchingpackets will take the same format as that of the IP, IPX, and AppleTalk packets respectively. Toprevent two commands from processing packets of the same protocol type in different ways, theswitch will prompt that you cannot set the etype-id argument for Ethernet II or snap packets to0x0800, 0x089B, or 0x8137.Associating a Port with a Protocol-Based VLANConfiguration prerequisitesz The protocol template for the protocol-based VLAN is configured.z The port is configured as a hybrid port, and the port is configured to remove VLAN tags when itforwards the packets of the protocol-based VLANs.Configuration procedureFollow these steps to associate a port with the protocol-based VLAN:To do… Use the command… RemarksEnter system view system-view —Enter port view interface interface-typeinterface-number —Associate the port with thespecified protocol-based VLANport hybrid protocol-vlanvlan vlan-id { protocol-index[ to protocol-index-end ] | all }RequiredBy default, a port is notassociated with anyprotocol-based VLAN.
