![]() ![]() PFC is not supported on switches with the Helix4 ASIC. This class can be EF, BE or any of the CSxx or AFxx classes. Sets the DSCP field in the packet header to the value represented by the DiffServ class value. ![]() Sets the DSCP field in packet header to a value, which can be either a decimal or hex value. ![]() Sets the datapath resource/queuing class value. You can specify one of the following targets for SETQOS/setqos: Option The iptables-/ ip6tables-based marking is supported with the following action extension: -j SETQOS -set-dscp 10 -set-cos 5įor ebtables, the setqos keyword must be in lowercase, as in: By default, if you do not include the -p option, cl-acltool looks for the policy file in /etc/cumulus/acl/policy.d/. Add the -p option to specify the location of the policy file. To enable traffic marking, use cl-acltool. Mark 802.1p CoS values in egress packets.To enable these rules, you do one of the following: You can mark traffic for egress packets through iptables or ip6tables rule classifications. Mellanox Spectrum, Spectrum-2, and Spectrum-3.Broadcom Tomahawk, Trident II, Trident II+, and Trident3.You can configure Quality of Service (QoS) for switches on the following platforms only: Unicast packets and multicast packets with the same priority value are assigned to separate queues, which are assigned equal scheduling weights. It applies strict priority to control traffic queues and a weighted round robin selection from the remaining queues. The scheduler is configured to use a hybrid scheduling algorithm. Service: Second-highest priority traffic.The choice to schedule packets based on COS or DSCP is a configurable option in the /etc/cumulus/datapath/nf file. Be sure to backup the original file before making changes.Įach packet is assigned to an ASIC Class of Service (CoS) value based on the priority value of the packet stored in the 802.1p (Class of Service) or DSCP (Differentiated Services Code Point) header field. It is best to make small, incremental changes to validate the changes with your application performance. The default thresholds defined in the nf file are intended for data center environments, but certain workloads may require additional tuning. The /usr/lib/python2.7/dist-packages/cumulus/_chip_config//nf assigns buffer space and egress queues.
