BreezeMAX Modular Base Station System Manual 219
Any number of L2 and/or VoIP Service Profiles may share the same VPL ID,
provided they all use the same Forwarding Rule.
Any number of PPPoE Service Profiles may share the same VPL ID, provided
they all use the same Forwarding Rule.
Any number of L2, VoIP and PPPoE Service Profiles may share the same VPL
ID, provided that all L2/VoIP Service Profiles use the same Forwarding Rule A,
and all PPPoE Service Profiles use the same Forwarding Rule B, where A and B
are different.
Available values are in the range of 0 to 4094 or null (empty string) for No VPL ID.
A value of 4095 is displayed for No VPL ID.
4.11.4.4.5 Priority Marking Mode
In some cases, the network operator may want to use the BreezeMAX system for
marking QoS classes, in order to provide network-wide QoS and enable the
upstream network to handle the traffic accordingly. Within the BreezeMAX
system, frames can be classified to QoS classes using Priority Classifiers, based
on either a DSCP header or 802,1p tag. This applies only in cases where an
external networking device marks the applicable fields. BreezeMAX also enables
marking data transmitted to the backbone network with either DSCP or 802.1p
values, where the marking is done per Service Profile. This marking overrides
marking performed by external devices behind the SU. Typically, Priority Marking
by the NPU will be used in the following cases:
The external networking equipment behind the SU does not use priority
marking.
The service provider does not trust the priority marking defined by the user's
equipment.
The service provider uses a priority marking type (DSCP or 802.1p) that differs
from the one used by the user's networking equipment.
The system supports three marking modes:
1 Transparent Marking Mode (No Priority Marking): In this case, the system
should forward the frames to the uplink network without any changes.
If 802.1p classification is used at the SU, the frames will be transmitted to the
operator's network according to the following rules:
