compound explicit-constituents
The range for the shared-shaping rate is 1000–1000000000 bps
(1 Kbps–1000 Kbps); the default is no shaping rate.
Use the operator and operandValue variables to specify the shared shaping rate
as an expression.
Burst is the catch-up number associated with the shaper; the range is 0–522240
(0–510 KB). Specifying 0 enables the router to select an applicable default value.
By default, shared shaping is set to auto , where the router selects the type of
shared shaping that is configured, depending on the line module. You must
specify the
compound keyword to actively shape voice and video traffic so that
the shared rate cannot be exceeded, and shape data queue rates to the value of
the shared rate minus the combined voice and video traffic rate. An error message
is generated if you specify
compound for line modules that do not support it,
and the router applies simple shared shaping.
3.
Configure the QoS profile and reference the scheduler profile.
(config)# qos-profile compound
(config-qos-profile)# atm-vc node
(config-qos-profile)# atm-vc node group AF
(config-qos-profile)# atm-vc node group EF
(config-qos-profile)# atm-vc queue traffic-class best-effort scheduler-profile
shared-1mbps
(config-qos-profile)# exit
TIP: The scheduler profile that you configured with the shared-shaping rate must be
referenced in the best-effort queue or the best-effort scheduler node.
4.
Attach the profile to the interface.
(config)# interface atm 11/0.10
(config-subif)# qos-profile subscriber-default-mode
(config-scheduler-profile)# exit
