esr(config-class-
policy-map)# shape
average <BANDWIDTH>
[BURST]
<BANDWIDTH> – committed
bandwidth in Kbps, takes the value of
[64..10000000];
<BURST> – size of the restrictive
threshold in KB, takes the value
[4..16000]. 128 KB.
15
Set the shared outgoing bandwidth
for a specific class. The class may
occupy the bandwidth if a lower
priority class has not occupied its
committed bandwidth. (if required)
esr(config-class-
policy-map)# shape
peak <BANDWIDTH>
[BURST]
16
Specify class operation mode.
(optionally)
esr(config-class-
policy-map)# mode
<MODE>
<MODE> – class mode:
fifo
– FIFO mode (First In, First

proceeded first.
18
Switch the class to the StrictPriority
mode and specify the class priority.
(if required)
esr(config-class-
policy-map)# priority
level <PRIORITY>
<PRIORITY> – priority level in
StrictPriority process, takes values of
[1..8].
Classes with the highest priority are
proceeded first. The default value:
tha class operates in WRR mode, the
priority is not specified.

Specify the limited number of virtual
queues. (optionally)
esr(config-class-

<QUEUE-LIMIT> – limited number of
virtual queues, takes values in the
range of [16..4096].
Default value: 16.
