Page 16: Qos Behaviors In A Traditional Stack
Quality of Service QoS queues On Ruckus ICX 7450 stacking devices only, Priority 7 multicast traffic is not treated as Strict Priority. Multicast queues in the Ruckus ICX 7450 are limited, so Priority 6 and Priority 7 Multicast traffic is mapped to Multicast Queue 7. Therefore, even if you configure Priority 7 as Strict Priority and Priority 6 as non-Strict, scheduling weight sched_6_wt+sched_7_wt is applied on Multicast Queue 7 so that Priority 7 traffic is not scheduled as Strict. -

The queue names listed in the table are the default names. -
Page 18: Qos Priorities-To-Traffic Assignment
Quality of Service QoS priorities-to-traffic assignment NOTE On a Ruckus ICX 7150, frames may be dropped before they are properly scheduled due to a shallow queue depth. Under this condition, configure the egress buffer profile to support WRR or Mixed mode and increase the port-share level of the profile. If you create a profile specifying only the weights without specifying the mechanism, the default mechanism is used. -
Page 19: Buffer Allocation And Threshold For Qos Queues
Quality of Service DSCP and CoS global re-marking When you change the priority, you specify a number from 0 through 7. The priority number specifies the IEEE 802.1 equivalent to one of the eight QoS queues on Ruckus devices. The numbers correspond to the queues as shown in the QoS queues table. Although it is possible for a packet to qualify for an adjusted QoS priority based on more than one of the criteria, the system always gives a packet the highest priority for which it qualifies. -
Page 20: Selecting The Qos Queuing Method
Quality of Service DSCP and CoS global re-marking The DSCP and CoS re-marking can be configured through the command-line interface (CLI) at the global level and the interface level. The global DSCP and CoS marking can coexist with other security features configured on the same port. The coexistence rules are the same as those for IPv4 ACLs. -

Page 23: Qos Mapping Configuration
Quality of Service QoS scheduling and queuing methods QoS mapping configuration You can optionally change the following QoS mappings: • DSCP to internal forwarding priority • VLAN priority (802.1p) to hardware forwarding queue, as described in Changing the VLAN priority 802.1p to hardware forwarding queue mappings on page 35 The mappings are globally configurable and apply to all interfaces. - Page 24 Quality of Service QoS scheduling and queuing methods NOTE In stacking mode, the qosp7 queue is reserved as Strict Priority under weighted queuing. Attempts to change the qosp7 setting are ignored. WRR is the default queuing method and uses a default set of queue weights. The number of packets serviced during each visit to a queue depends on the percentages you configure for the queues.

Page 25: Ipv6 Qos
Quality of Service Flow control and buffer management IPv6 QoS QoS features supported for IPv6 environments include packet classification, queueing, traffic shaping, packet marking, and policing of IPv6 packets. These features are available for all FastIron products. The feature set is identical to that in IPv4. To implement QoS in networks running IPv6, follow the same steps as those to implement QoS in networks running only IPv4. - Page 26 Quality of Service Flow control and buffer management Because multiple priorities can be mapped to a single PG, congestion on one priority in a PG may generate a pause, stopping transmission of all priorities in that PG. Therefore, it is important to create a custom priority-to-PG map to meet your application needs, using either PFC pause honoring or PFC pause transmission.

Quality of Service Configuring QoS Egress buffer management This mechanism tracks buffer utilization on a per-egress port and priority basis. As these accounting structures reach the limit, packets that are destined to the congested egress port-priority are tail-dropped. The aim of the mechanism is to support fair access to the buffering resources among congested egress ports. -
