Function
Specifies the name for a scheduler.
Sets the transmission priority of the scheduler,
which determines the order in which an output
interface transmits traffic from the queues.
You can set scheduling priority at different
levels in the order of increasing priority from low
to high.
A high-priority queue with a high transmission
rate might lock out lower-priority traffic.
Defines the size of the delay buffer.
By default, queues 0 through 7 are allotted the
following percentage of the total available
buffer space:
Queue 0—95 percent
Queue 1—0 percent
Queue 2—0 percent
Queue 3—0 percent
Queue 4—0 percent
Queue 5—0 percent
Queue 6—0 percent
Queue 7—5 percent
NOTE: A large buffer size value correlates with
a greater possibility of packet delays. Such a
value might not be practical for sensitive traffic
such as voice or video.
Specifies the rate at which queues transmit
packets.
Your Action
To name a scheduler, type the name—for
example, .
be-scheduler
To set a priority, select one:
low—Packets in this queue are transmitted
last.
strict-high—Packets in this queue are
transmitted first.
To specify no scheduling priority, select the
blank.
To define a delay buffer size for a scheduler,
select the appropriate option:
To specify no buffer size, select the blank.
To specify buffer size as a percentage of the
total buffer, select Percent and type an
integer from 1 through 100.
To specify buffer size as the remaining
available buffer, select Remainder.
NOTE: On EX8200 switches, you can specify
the buffer size as a temporal value. The queuing
algorithm will then drop packets once it has
queued a computed number of bytes. This
number is the product of the logical interface
speed and the configured temporal value.
To specify shaping rate as a percentage,
select Percent and type an integer from 1
through 100.
To specify shaping rate as a number, select
Rate and enter a value.
To specify no shaping rate, select the blank.
