Following are some of the QoS features supported in the Cisco Catalyst 3750-X and 3560-X Series Switches:
●
Cross-stack QoS allows QoS to be configured across the entire stack (available only on the Catalyst
3750-X).
●
802.1p class of service (CoS) and differentiated services code point (DSCP) field classification are
provided, using marking and reclassification on a per-packet basis by source and destination IP address,
MAC address, or Layer 4 TCP/UDP port number.
●
Cisco control-plane and data-plane QoS ACLs on all ports help ensure proper marking on a per-packet
basis.
●
Eight egress queues per port help enable differentiated management of different traffic types across the
stack. Four queues are user configurable and four are reserved for system use.
●
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.
●
Up to 64 aggregate or individual policers are available per Fast Ethernet or GbE port.
Location Awareness and Mobility
In order to provide delivery of a best-in-class network experience to end users, it's critical for network access to be
location aware. A wide variety of devices can appear on the network, both wired (switches, routers, IP phones,
PCs, access points, controllers, video digital media players, and so on) and wireless (mobile devices, wireless
tags, rogues, and so on). In many industries, locating assets is primarily a manual process and is time consuming
and error prone. The inability to locate assets in real time and to help ensure their availability when and where they
are needed limits reaction time and efficiency.
Location services answer business-critical questions about both mobile assets and the users of those assets
regardless of whether those assets are connecting using wired or wireless, and hence directly improve their
organization's profitability. Network Location Services also improve security and accelerate client troubleshooting
by locating an asset, user, or device on the network.
●
Network visibility and control provide centralized visibility into wired and wireless devices on the network
and their location.
●
Location-assisted client troubleshooting enables tracking of wired or wireless clients for quick problem
resolution.
●
Asset tracking and improved security provide centralized inventory of wired and wireless devices and asset
management for improved business processes.
●
Cisco Mobility Service Engine (MSE) Open API provides an open API (based on Simple Object Access
Protocol [SOAP] and XML protocol) for any business application that needs the location data.
