●
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.
Application Visibility and Control Using Flexible NetFlow (FNF)
Cisco IOS Software FNF is the next generation in flow visibility technology, allowing optimization of the network
infrastructure, reducing operation costs, and improving capacity planning and security incident detection with
increased flexibility and scalability. The Cisco Catalyst 3650 provides optimized application visibility with FNF
across wired plus wireless. The switch is capable of 48,000 flow entries on 48-port models and 24,000 flow entries
on 24-port models across wired and wireless. With UADP ASIC, Cisco Catalyst 3650 delivers next-generation flow
technology with unprecedented flexibility and comprehensive visibility extending from Layer 2 (MAC and VLAN) to
Layer 4 (TCP/UDP) flags and so on across wired plus wireless traffic. The Cisco Catalyst 3650 switch is Medianet
capable to provide visibility and troubleshooting capabilities across wired plus wireless video traffic. Specific
Medianet features will be enabled in future software updates.
The flow data collected by FNF can be exported to an external collector for analysis and reporting or tracked by
the EEM. The Cisco Catalyst 3650 enables powerful on-box and customizable event correlation and policy actions
with EEM, allowing the switches to trigger customized event alarms or policy actions when the predefined
condition is met. With no external appliance required, customers are able to use existing infrastructure to perform
traffic monitoring, making traffic analysis economical even on a large IP network.

High-performance video over wireless integrates Cisco VideoStream technology to optimize the delivery of video
applications across the WLAN.
Wired plus wireless IP telephony supports
unified communications for improved collaboration through messaging,
presence, and conferencing and supports all Cisco Unified Communications wireless IP phones for cost-effective,
real-time voice service.
