Configuration prerequisites
Create a VLAN before configuring a protocol-based VLAN.

Table 52 Create protocol types of VLANs
Operation

Create the protocol 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.
c
CAUTION: In a VLAN, it is not allowed to configure two templates with the same
protocol type and encapsulation format. If any parameter in a user-defined
template has the same value as the corresponding parameter in the standard
template, the user-defined template and the standard template cannot be
configured in the same VLAN.
Pay attention to the following notices about the template configuration
It is not allowed to configure both ipx llc standard template and LLC
■
user-defined template whose dsap-id and ssap-id are both 0xe0 in the same
VLAN.
It is not allowed to configure both ipx raw standard template and LLC
■
user-defined template whose dsap and ssap are both ff in the same VLAN.
It is not allowed to configure both ipx ethernetii standard template and
■
EthernetII user-defined template whose etype is 8137 in the same VLAN.
It is not allowed to configure both ipx snap standard template and SNAP
■
user-defined template whose etype is 8137 in the same VLAN.
When the values of the dsap-id and ssap-id arguments are AA, the packet
■
encapsulation type is not llc but snap. To avoid template conflict, the system
disable the value AA for the dsap-id and ssap-id arguments when you
configure LLC user-defined template.
In addition, pay attention to the following notices about IP template
If a packet can match both Ipv4-based VLAN and the VLAN based on other
■
protocol, Ipv4-based VLAN takes higher priority.
