Class Weighted Round Robin
Incoming traffic flows from various applications can be prioritized and provisioned using a
weighted round-robin scheduling algorithm.
Class weighted round robin can be configured using the following command:
[root@host~]# cxgbtool <ethX> sched-class params type packet level cl-wrr
channel <Channel No.> class <scheduler-class-index> weight <Y>
Here,
ethX : Chelsio interface.
Channel No. : Port on which data is flowing (0-3).
scheduler-class-index : TCP traffic class (0-14 for T4 adapters; 0-15 for T5/T6 adapters).
weight : Weight to be used for a weighted-round-robin scheduling hierarchy.
Possible values include 1 to 99.
Channel Rate Limiting
This scheduler hierarchy level can be used to rate limit individual channels.
Channel rate limiting can be configured using the following command:
[root@host~]# cxgbtool eth6 sched-class params type packet level ch-rl rate-
unit <scheduler-rate-unit> rate-mode <scheduler-rate-mode> channel 1 max-
rate <maximum-rate>
Here,
ethX : Chelsio interface.
scheduler-rate-unit : Specifies whether the traffic management rule is configured for bit-
rate or packet-rate. Possible values include
bits or pkts.
scheduler-rate-mode : Specifies whether the traffic management rule is configured to
support a percent of the channel rate or an effective rate.
Possible values include
relative or absolute.
Channel No. : Port on which data is flowing (0-3).
maximum-rate : Bit rate (Kbps) for this TCP stream. The lower limit is 1 Gbps.
