There are several new features included in this release, which are as following.
• Cisco EnergyWise: The inclusion of Cisco EnergyWise technology in this release enables companywide optimization of greenhouse gas (GhG) emissions by measuring, reporting, and reducing energy consumption across the entire corporate infrastructure.
• Identity-based networking: This release continues to enhance Cisco Identity-based Networking Services (IBNS) with several primary innovations to simplify configurations that support heterogeneous endpoint device environments. The release also includes innovations to transparently integrate with existing network and Internet Protocol Telephony (IPT) infrastructure and to provide IT administrators comprehensive policy enforcement options. These enhancements are covered in detail under “Security and Identity Enhancements” section.
• Auto Smartports: This release extends Smartports to allow dynamic switch port provisioning. The switch uses Cisco Discovery Protocol to determine the type of the device connected to the switch and automatically provisions the port based on the predefined macros. The switch integrates with RADIUS for device authentication and applies the macro based on the RADIUS-assigned tag.
• Wired location services: This enhancement enables switch port tracking of hosts or users connected to switches. As part of the location service, the switch integrates with Cisco wireless Mobility Services Engine, which can be used for host/user lookup in determining the switch connectivity for troubleshooting purposes.
• LLDP-MED integration for class of service/diff services code point (CoS/DSCP): Switch will signal CoS/DSCP settings to connected IP telephone using Link Layer Discovery Protocol for Media Endpoint Devices (LLDP-MED) (so that the IP telephone can use the values for communication)
• IP Source Guard (IPSG) and Dynamic Address Resolution Protocol (ARP) Inspection (DAI) support for Cisco Catalyst 2960 Series Switches with LAN Base software: This release introduces IPSG and DAI capabilities for Layer 2 security.
• IPv6 packaging changes: Cisco has announced the end of life for Advanced IP Services (AIS). Functionality previously available in AIS has been migrated to IP Services or IP Base as documented in Table 1.
Cisco has appointed a select group of Cisco Engineers to develop a state-of-the-art security force. ‘The Realm.” growing beyond the systems in which they were created into a group of powerful defenders. Forming a unified league of security, the defenders battle Botnets, Malware, Spam and Intruders in the Realm, assuring the safety and security of every citizen on the human network.
‘The Realm.”is an online comic that animates the pane flow and adds voice narration. Creatively it’s an engaging experience, not as complete as a full scale animation but more alive that just a flat 2D image.

What do you think what happens? If a new Cisco Catalyst® switch is placed between any two VTP domains, the Cisco Catalyst® switch will join the VTP domain identified by the first VTP update it receives. Just check the below example.
The VTP domain can be changed to another in a Cisco Catalyst® switch by using the CLI prompt, this is the only way you can change.

The technical presentations were simply great I would say they were meeting the Networkers standards.
Some of the topics covered as follows which can be downloaded.
Switch C is added to the network connecting via a trunk port to Switch B with no VTP domain configured, in this mode when the Switch C receives the first VTP update from the adjacent Switch B , it will become the part of the VTP domain ITKE as identified in the VTP update.
If you all are looking for a complete green solution for your Data Center using Cisco Catalyst® switches, there is good news with Cisco EnergyWise software. The most interesting fact of the innovative Cisco EnergyWise technology for Cisco Catalyst® switches that measures, reports and reduces the energy consumption of Internet Protocol (IP) devices such as phones, laptops and access points. Cisco also announced industry partner solutions along with an intelligent middleware acquisition that will ultimately enable the management of power consumption for entire building systems such as lights, elevators, and air conditioning and heating.

In my previous post I just introduced the VLAN trunking protocol; let’s talk about the VTP domain.
The VTP domain is a logical group of switches that will share VLAN information. Each switch can belong only to one VTP domain in addition to sharing the VLAN information with all other Cisco Catalyst Switches in the same VTP domain. Cisco Catalyst Switches in different VTP domains drops any VTP updates received from Cisco Catalyst Switches.
