Superior QoS
The Cisco Catalyst 3650 Series offers Gigabit Ethernet speed with
intelligent services that keep traffic flowing smoothly, even at 10
times the normal network speed. Industry-leading mechanisms for
cross-stack marking, classification, and scheduling deliver
superior performance for data, voice, and video traffic, all at
wire speed.
The following are some of the QoS features supported in the Cisco
Catalyst 3650 Series Switches:
●Granular wireless bandwidth management and fair sharing use Cisco’s
proven Cisco IOS Software and UADP ASIC technology to provide
hierarchical bandwidth management at line rate (per access point,
per radio, per SSID, per client-based policies). Fair sharing
across the users within an SSID makes sure that no single user is
starved because of other heavy-hitting users. Fair sharing is
automatically enabled for wireless at user level as well as SSID
level.
●802.1p CoS and DSCP field classification is provided, using marking
and reclassification on a per-packet basis by source and
destination IP address, MAC address, or Layer 4 Transmission
Control Protocol/User Datagram Protocol (TCP/UDP) port number.
●Shaped round robin (SRR) scheduling helps ensure differential
prioritization of packet flows by intelligently servicing the
ingress queues and egress queues. Weighted tail drop (WTD) provides
congestion avoidance at the ingress and egress queues before a
disruption occurs. Strict priority queuing helps ensure that the
highest priority packets are serviced ahead of all other traffic.
●The Cisco committed information rate (CIR) function provides
bandwidth in increments as low as 8 Kbps.
●Rate limiting is provided based on source and destination IP
address, source and destination MAC address, Layer 4 TCP/UDP
information, or any combination of these fields, using QoS ACLs (IP
ACLs or MAC ACLs), class maps, and policy maps.
●Eight egress queues per port for wired traffic and four egress
queues for wireless help enable differentiated management of
different traffic types across the stack for wired traffic. Up to
2000 aggregate policers are available per switch.
