Operation
Create
template for the VLAN
When you are creating protocol templates for protocol-based VLANs, the at, ip and ipx
keywords are used to create standard templates, and the mode keyword is used to
create user-defined templates.
Caution:
Because the IP protocol is closely associated with the ARP protocol, you are
recommended to configure the ARP protocol type when configuring the IP protocol
type and associate the two protocol types with the same port, in case that ARP
packets and IP packets are not assigned to the same VLAN, which will cause IP
address resolution failure.
The mode llc dsap ff ssap ff and ipx raw keywords match the same type of
packets, the ipx raw keyword takes precedence over the mode llc dsap ff ssap ff
keyword, and a packet will not be further matched if it does not match the ipx raw
keyword, therefore, the protocol-vlan mode llc dsap ff ssap ff command takes no
effect.
Packet encapsulation type is snap, instead of llc, if the values of the dsap-id and
ssap-id arguments are both AA.
When you use the mode keyword to configure protocol-based VLANs, if you set the
etype arguments of Ethernet II or SNAP packets to 0x0800, 0x089b, and 0x8137,
the matched packets have the same format as that of IP, IPX, and AppleTalk
packets respectively. In order that the two commands do not configure the same
protocol repetitively, the switch will prompt that you cannot specify the etype
arguments of Ethernet II and SNAP packets to 0x0800, 0x089b, and 0x8137.

2.3.2 Associating a Port with the Protocol-Based VLAN

I. Configuration prerequisites
The protocol template for the protocol-based VLAN is created
The port is configured as a hybrid port, and the port is configured to remove VLAN
tags when it forwards the packets of the protocol-based VLANs.
