2.
DiffServ
– enables or disables DiffServ (DSCP) priorities for any available switch port
– LAN1/2/3/4, WAN or Mng (command line –
ethernet QoS DSCP
[enable | disable
<port>] | map)
;
3.
Port based priority –
allows passing packets from available ports directly to a
specific priority queue. By default port based priority queuing passes packets from
all ports to lowest (1) priority queue (command line –
ethernet QoS port
<port>
<priority>);
4.
Queuing priority selection –
allows to select primary QoS method, upon which
queueing decision shall be made;
5.
Queuing type –
allows choosing fixed priority queuing mode or weighted queuing
mode;
6.
Weights (0<Q1<Q2<Q3<Q4<50) –
allows specifying correlation of all four queues.
Queue values should correspond to limitations. Default correlation is 1:2:4:8.
7.
Pressing
„Execute configuration”
applies changes made to the corresponding
section only for the local side CFIP Lumina. If
„Rollback on”
is selected, configuration
will be reverted in case of erroneous configuration changes applied;
8.
Writes to configuration file all the changes made on the whole page (command line
–
cfg write
);
9.
Execution status -
in case of error or incorrectly entered parameter value, or other
problems on the whole page – the info message is being shown here. Otherwise it
says “Ok”.

Weighted priority queuing mode
Figure 4.13.
Fixed priority queuing mode
In case of weighted priority queuing mode, highest (q3) priority buffer may pass up to 8
consecutive packets subsequently proceeding to lower priority buffer (q2), which may pass up to 4
consecutive packets. This means that highest priority after passing 8 consecutive packets will wait no
longer than until 7 packets of lower priorities pass (4(q2)+2(q1)+1(q0)).
