For disabling limiting of bandwidth for all services and enable limiting separately,
disable downstream one-police and set downstream policer peak-rate for required
services.
30.1.2
Configuring upstream shaping
Shaping allows limiting all types of traffic for services by bandwidth or set different values of
bandwidth for each type separately.
There is an opportunity to limit bandwidth for multicast and broadcast traffic separately. In this case
unicast traffic will be limited by the global value.
If you set the limit for unicast traffic, you should set limits for multicast and broadcast traffic as well.
Otherwise, multicast and broadcast traffic will not be limited at all.
For the correct bandwidth limiting, different DBA profiles should be assigned for each service.
Step 1.
Enable
shaping
for required services and set commited-rate and peak-rate values for global
limiting.
LTP-8X(config-shaping)("shaping-00")# upstream 0 enable
LTP-8X(config-shaping)("shaping-00")# upstream 0 commited-rate 100000
LTP-8X(config-shaping)("shaping-00")# upstream 0 peak-rate 110000
If you stop configuring on this step, all the traffic of service 0 will be limited by the commited-rate
value.
Step 2.
Enable
shaping
for different traffic types
LTP-8X(config-shaping)("shaping-00")# upstream multicast 0 enable
LTP-8X(config-shaping)("shaping-00")# upstream broadcast 0 enable
LTP-8X(config-shaping)("shaping-00")# upstream unicast 0 enable
Step 3
. Specify parameters of fixed bandwidth for each traffic type for service 0
LTP-8X(config-shaping)("shaping-00")# upstream multicast 0 commited-rate 500
LTP-8X(config-shaping)("shaping-00")# upstream multicast 0 peak-rate 600
LTP-8X(config-shaping)("shaping-00")# upstream broadcast 0 commited-rate 500
LTP-8X(config-shaping)("shaping-00")# upstream broadcast 0 peak-rate 600
LTP-8X(config-shaping)("shaping-00")# upstream unicast 0 commited-rate 100000
LTP-8X(config-shaping)("shaping-00")# upstream unicast 0 peak-rate 100000
Similarly, the bandwidth is configured for other services.
The value of bandwidth is specified in Kbps (1000 bps) and rounded down to 64-fold value.
For NTU-1, the algorithm of bandwidth limiting in upstream is different:
traffic types are independent: if the limit of unicast traffic is set, multicast and
broadcast traffic will be limited by the global value.
in case the global value is specified as well as values for different traffic types,
the limit for different traffic types will be implemented first, then limiting by the
global value.
the traffic for all services is limited by the value set for service 0.
