•
CBS value (in bytes)
•
EBS value (for algorithm type srtcm only)
•
PIR value (for algorithm type trtcm only)
•
PBS value (for algorithm type trtcm only)
•
Green action
•
Yellow action (for algorithm types trtcm and srtcm only)
•
Red action
Options
The following table gives the range of values for each option that can be specified with
this command and a default value (if applicable).
Example
--> meter show profile mp3
red

by the classifier profile set rule priority command). This value determines the scheduling
behavior received by a packet. If a packet is not classified, scheduling priority 0 is assigned
to the packet by default.
If you select the priority service discipline, the profile supports 8 queues, each corre-
sponding to a scheduling priority from 0-7. Each queue can hold a maximum of 32 pack-
ets at any instant. Scheduling priority value 0 assigns the lowest priority while 7 assigns
the highest priority.
If you select the WF2QPlus service discipline, the weight value (percentage) configured
for a scheduling priority determines the share of bandwidth received by packets belong-
ing to the scheduling priority level. A single default queue with a weight of 100% is cre-
ated by default. Packets with scheduling priority 0 are always enqueued in the default
queue. You may configure weights for scheduling priority levels (1-7) using the scheduler
profile set queue weight command.
If you do configure weight for a scheduling priority level, the corresponding packets are
enqueued in a separate queue and the bandwidth is allocated in accordance with the con-
figured weights. Otherwise, packets are enqueued in the default queue.
Each queue can hold a maximum of 32 packets at any instance.
In addition, this created scheduler profile may be configured with shaping and algorithmic
dropper (RED/WRED):
•
Shaping
: you can configure the scheduler profile for shaping by using the scheduler
set profile shaping command. Shaping is disabled by default.
•
Algorithmic Dropper
: you can configure Algorithmic Dropper (RED/WRED) for a
queue by using the scheduler profile set queue ald profile command.
You can set the profile to work on a transport by using the transport set scheduler pro-
file command.

7.1.6.2.5 SCHEDULER SET PROFILE SHAPING
Syntax
SCHEDULER SET PROFILE <name> SHAPING <MaxRate> <MaxBurst>
Description
This command configures the specified scheduler profile to shape aggregate traffic to the
specified maximum rate and burst size.
To disable shaping, set
<MaxRate>
and
<MaxBurst>
values to 0 and apply the profile to
the transport using the
TRANSPORT SET SCHEDULER PROFILE
command.
If scheduler is applied over an Ethernet interface, the padding and FCS are not taken into
account. When applied over other types of interfaces, the extra bytes added by devices
lower than scheduler may not be taken into account. For example, when configured over
an ATM interface, the padding and trailer added by AAL5 are not taken into account.

this command and a default value for each option (if applicable).
