Associating A Port With A Protocol-Based Vlan - H3C S5100-SI Series Operation Manual

Operation Manual – VLAN
H3C S5100-SI/EI Series Ethernet Switches
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 to avoid that ARP
packets and IP packets are not assigned to the same VLAN, which will cause IP
address resolution failure.
If you specify some special values for both the dsap-id and ssap-id arguments when
configuring the user-defined template for IIc encapsulation, the matching packets
will take the same encapsulation format as some standard type of packets. For
example, when both dsap-id and ssap-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 llc packets; if they
both have a value of 0xAA, the packet encapsulation format will be the same as that
of snap packets. To prevent two commands from processing packets of the same
protocol type in different ways, the system does not allow you to set both the dsap-id
and ssap-id arguments to 0xFF, 0xE0, or 0xAA.
When you use the mode keyword to configure a user-defined protocol template, if
you set the etype-id argument for ethernetii or snap packets to 0x0800, 0x8137, or
0x809B, the matching packets will take the same format as that of the IP, IPX, and
AppleTalk packets respectively. To prevent two commands from processing
packets of the same protocol type in different ways, the switch will prompt that you
cannot set the etype-id argument for Ethernet II or snap packets to 0x0800, 0x8137,
or 0x809B.

2.3.3 Associating a Port with a Protocol-Based VLAN

I. Configuration prerequisites
The protocol template for the protocol-based VLAN is configured.
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.
II. Configuration procedure
Follow these steps to associate a port with the protocol-based VLAN:
Enter system view
