• Data confidentiality & Integrity
• Flexibility: Selectively enable MACSec on links where needed
• Network Intelligence: Intermediate network devices can inspect, monitor, and forward
MAC Authentication Bypass (MAB) - configurable user name and password
This feature allows the user to configure the format of the MAC address used in the username and password fields in the RADIUS Access-Request packet for MAB authentication. This allows the easy inter-operatibility with RADIUS servers or MAC databases which expect the MAC address in a different format than provided by the switch as default.
This feature enables CTS-SXP syslogs to be generated whenever a change to IP-to-SGT binding occurs (add, delete, change). These changes are learned and propagated on the CTS-SXP connection.
Medianet is Cisco's end-to-end IP architecture that enables pervasive and quality rich-media (video, voice and data) experiences. A Medianet reduces total cost of ownership and scales video through features such as auto-configuration and media monitoring. At the same time, it helps to ensure a quality user experience while optimizing bandwidth use and efficiency.
Media Monitoring enhances visibility into the network to simplify, generate baselines, and accelerate troubleshooting of video, voice, and data applications, and validates network capacity and configuration before deploying new applications or before events.
Media Monitoring is composed of three features: Performance Monitor, Mediatrace, and IP SLA video operation (VO). These three features form a suite of tools to help enable the network operator to perform media performance monitoring and troubleshooting.
• Performance Monitor allows administrators to analyze the performance of rich-media traffic across the network to provide a holistic view of the network service being delivered.
• Mediatrace discovers Layer 2 and Layer 3 nodes along a flow path. Mediatrace implicitly uses Performance Monitor to provide a dynamic hop-by-hop analysis of media flows in real time to facilitate efficient and targeted diagnostics.
• IP SLA VO (Video Operations) generates synthetic traffic streams that are very similar to real media traffic. It can be used in conjunction with Mediatrace to perform capacity planning analysis and troubleshooting even before applications are deployed.
Media Awareness and Auto configuration
Cisco endpoints are equipped with the Media Services Interface (MSI) a software component that helps enable endpoints to consistently make use of intelligent network services to improve the quality of experience and reduce the cost of deployment and operations.
Media Services Proxy (MSP) helps by recognizing the type of flow by gleaning a limited set of signaling protocols (RTSP, SIP, H323) to provide same functionality to non-cisco endpoints.
Cisco AutoQoS simplifies quality-of-service (QoS) deployment for video endpoints by providing end to end QoS for voice, data and video traffic.
Wired Location Services
The wired location solution is designed to track the location of devices as they move around the network. Central location management is done with Cisco MSE whereas Campus switches communicate location info with MSE via NMSP protocol.
New NMSP enhancements in this release are as below:
• Location at switch level
• Local timezone change
• GPS support for location
• Priority settings for MIBs
• Name value pair
Wireshark based Ethernet Analyzer Application
Wireshark based Ethernet Analyzer is an IOS-XE based built-in open source packet analyzer application using Application Hosting Capabilities of IOS XE for network analysis, monitoring and troubleshooting without the need for external sniffer. Wireshark will be available on Cisco® Catalyst® 4500 Series Supervisor Engine 7-E, Supervisor Engine 7L-E and C4500-X starting IOS XE3.3.0SG.

Starting with Cisco IOS Release 3.3.0SG and 15.1(1)SG, Energywise will provide support for following features:
Expand Endpoint device support
• New version of toolkit and API based partner integration
Easy Virtual Network (EVN) is Cisco's IP-based network virtualization solution that provides traffic separation and path isolation on a shared network infrastructure. EVN uses existing Virtual Route Forwarding (VRF)-Lite technology to Simplify Layer 3 network virtualization, Improve shared services support and Enhance management, troubleshooting.
This feature in OSPFv3 allows nonstop data forwarding along routes that are already known while the OSPFv3 routing protocol information is being restored.
HSRPv2 Global IPv6 address Support
The HSRP global IPv6 address feature allows users to configure multiple nonlink local addresses as virtual addresses, and it allows for the storage and management of multiple global IPv6 virtual addresses in addition to the existing primary link-local address. If an IPv6 address is used, it must include an IPv6 prefix length. If a link-local address is used, it must not have a prefix.
NSF support extended from Enterprise Services to IP Base
Starting with Cisco IOS Release 3.3.0SG and 15.1(1)SG, support for NSF (NSF for BGP, OSPF and EIGRP) has been extended from Enterprise Services to IP Base feature set.
