To do...
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.
Caution:
In a VLAN, it is not allowed to configure two templates with the same protocol type and
encapsulation format. The encapsulation defined by the user-defined template is the
same as that defined by a standard template if the parameters of the user-defined
template adopt some special values. In this scenario, 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 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
disables 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.
ip [ ip-address [ net-mask ] ] defines IPv4-based VLAN. If you want to define the
VLANs based on IP or other encapsulation formats, use mode { ethernetii [ etype
etype-id ] } and snap [ etype etype-id ], in which, etype-id is 0x0800.
Use the command...
protocol-vlan [ protocol-index ] { at |
ip [ ip-address [ net-mask ] ] | ipx
{ ethernetii | llc | raw | snap } | mode
{ ethernetii [ etype etype-id ] | llc
[ dsap dsap-id [ ssap ssap-id ] | ssap
ssap-id ] | snap [ etype etype-id ] } }
