QoS
(Quality
of
Service)
Configuration
The
POEGEM24T4SFP
support
four
QoS
queues
per
port
with
strict
or
weighted
fair
queuing
scheduling.
There
are
24
QoS
Control
Lists
(QCL)
for
advance
programmable
QoS
classification,
based
on
IEEE
802.1p,
Ethertype,
VID,
IPv4/IPv6
DSCP
and
UDP/TCP
ports
and
ranges.
The
QoS
classification
looks
for
information
up
to
Layer
4,
including
IPv4
and
IPv6
DSCP,
IPv4
TCP/UDP
port
numbers,
and
user
priority
of
tagged
frames.
This
QoS
classification
mechanism
is
implemented
in
a
QoS
control
list
(QCL).
The
QoS
class
assigned
to
a
frame
is
used
throughout
the
device
for
providing
queuing,
scheduling,
and
congestion
control
which
is
guaranteed
to
the
frame
according
to
what
was
configured
for
that
specific
QoS
class.
The
switch
supports
advanced
memory
control
mechanisms
providing
excellent
performance
of
all
QoS
classes
under
any
traffic
scenario,
including
jumbo
frames.
The
ingress
super
priority
queue
allows
traffic
recognised
as
CPU
traffic
to
be
received
and
queued
for
transmission
to
the
CPU
even
when
all
the
QoS
class
queues
are
congested.
