access-ingress-aggregate-rate access-ingress-aggregate-rate [unshaped-sap-cir cir-rate]
config>system>qos
This command sets the rate for fabric shapers on the 7705 SAR-A, 7705 SAR-Ax, 7705 SAR-H, 7705 SAR-Hc, 7705 SAR-M, or 7705 SAR-Wx for access ingress traffic. The rate represents the maximum bandwidth that the node can switch through its fabric interface. Only aggregate mode is supported.
This command is not supported on the 7705 SAR-X, where the shaper rate is set permanently to 16 Gb/s.
The unshaped-sap-cir command is optional. When used, it assigns a cir-rate to the unshaped SAP aggregate so that the unshaped SAP aggregate rate can compete with the shaped SAPs when the round-robin fabric scheduler selects traffic to forward to the switching fabric. When not used, the cir-rate is set to its default value of 0 kb/s. If the cir-rate is max, the maximum possible backplane speed is used.
The access-ingress-aggregate-rate can be higher or lower than the cir-rate. If the cir-rate is higher than the access-ingress-aggregate-rate, then the cir-rate is used by the network processor, but backpressure from the fabric shaper is applied indirectly to the per-SAP queues, as follows:
per-SAP (aggregate) shapers—that is, unshaped SAP aggregate CIR or individual shaped SAP CIRs—prioritize traffic towards the fabric shaper based on the cir-rate
the fabric shaper shapes the traffic at the configured rate
when the fabric shaper becomes congested, it applies backpressure to individual SAP shapers—that is, it applies backpressure to shaped SAPs and to unshaped SAP aggregate, which in turn applies backpressure to individual unshaped queues
500000 (‟default”) for access-ingress-aggregate-rate
0 for cir-rate
the PIR rate of the fabric shapers for access ingress traffic, in kb/s. Using the default keyword sets the aggregate rate to 500 000 kb/s.
the CIR rate of the unshaped SAP shaper for access ingress traffic, in kb/s. Using the max keyword sets the CIR rate to the maximum possible backplane speed.
network-ingress-aggregate-rate network-ingress-aggregate-rate
config>system>qos
This command sets the rate for fabric shapers on the 7705 SAR-A, 7705 SAR-Ax, 7705 SAR-H, 7705 SAR-Hc, 7705 SAR-M, or 7705 SAR-Wx for network ingress traffic, in kb/s. The rate represents the maximum bandwidth that the node can switch through its fabric interface. Only aggregate mode is supported.
This command is not supported on the 7705 SAR-X, where the shaper rate is set permanently to 16 Gb/s.
2000000 (‟default”)
the rate of the fabric shapers for network ingress traffic, in kb/s. Using the default keyword sets the aggregate rate to 2 000 000 kb/s (2 Gb/s).
