Table 4-6: Hybrid Vlan Mode - Nera WiLink-I Series System Manual

Hybrid VLAN Mode of operation enables classification of both tagged and
untagged packets or untagged packets only, according to the following rules:
Hybrid VLAN
Mode
Off
On
The guidelines that should be followed when defining VLAN IDs and related
parameters are:
A specific VLAN ID behind a certain SU can be associated only with a single
¢
Service of a certain Service Type. It is not possible to define two Services of the
same Service Type for the same SU and VLAN ID. However, the same SU and
VLAN ID can be associated with two Services of different Service Types,
excluding the combination of L2 Service and Voice Service.
For each Service Type, a maximum of one Service that enables forwarding of
¢
untagged packets can be assigned to an SU. Forwarding of untagged packets
is supported when either Hybrid VLAN Mode is On, or Hybrid VLAN Mode is
Off and the VLAN List is empty. It is not possible to define for the same SU two
Services of the same Service Type that enable forwarding of untagged packets.
However, the same SU and untagged packets can be associated with two
Services of different Service Types, excluding the combination of L2 Service
and Voice Service.
The maximum total number of VLAN IDs behind the same SU is 16 (15 when
¢
there is a Service with Hybrid VLAN Mode On is assigned to the SU).
The combination of VLAN Transparency Service On, Hybrid VLAN Mode Off
¢
and an empty VLAN List means that all packets are forwarded. This
combination should be used only if the Service Provider can ensure that there
will not be conflicts between VLAN IDs used by devices behind the SU and
existing VPL IDs.
