This command can give a good idea of the size of the CAM table and how many hosts are using the network.
From the above example you can notice how many mac address are used by each vlan and how many free mac address are available
A useful command for troubleshooting purpose as well as it’s a part for CCNP Switch 642-813 curriculum.
Recently one of our vendor added couple of new Cisco Catalyst 4506 Series distribution switches to our network for their PACS project. Those two newly added Cisco 4506 Series distribution switches are connected to our Core Cisco Catalyst 6513Series Switches using a layer 23 uplink ( as a trunk port). For VLAN redundancy we are using HSRP protocol. The newly added Cisco 4506 Series distribution switches are configured in VTP Client mode, we could see the VTP status was updated and all the VLAN were created. But there was a problem; there was not communication between any of the VLANS in the new Cisco 4506 Series distribution switches, after trouble shooting we figured out “ip routing” was enabled. When we disabled the ip routing with “no ip routing” command everything started working.
The importance of remote connectivity is growing, VPN has become quite essential for each and every organizations starting from Enterprises to a SMB. These days’ people started using the smartphones for VPN connectivity including me. This is an era of iPhones, iPads, Black berries etc.
There is a good news for iPhone users as Juniper Network one of the leading network security company has released Junos Pulse app, which provides secure remote mobile access to corporate resources on an iPhone or iPod Touch. Junos Pulse app happens to be the industry’s first downloadable VPN app for iPhone, coupled with the Juniper Networks SA Series SSL VPN Appliances, a remote user can now have the privilege of accessing any corporate resource from the iPhone and iPod touch enabling the mobile workforce to stay connected, productive and informed while on the run.
Mark Bauhaus, executive vice president and general manager of Juniper’s Service Layer Technologies Business Group said on the release of the app: “Instant and seamless secure access to corporate resources including applications, email, contacts and the intranet are all critical elements demanded by employees of any successful organization. We worked with Apple to ensure the Junos Pulse App enables the productivity that enterprise users are demanding and are very excited that it is now available on the App Store. Juniper’s market-leading SSL VPN solution will keep any enterprise mobile, secure, empowered and working more efficiently.”
The Junos Pulse app works on iPhone and iPad with an iOS version of 4.1 or later. On the infrastructure side, customers must have a Juniper Networks SA Series SSL VPN Appliance running version 6.4 or later.

AMD has revealed details of two of its next generation x86 processor cores, codenamed Bulldozer and Bobcat.
The newly revealed two core designs are meant for high end PCs and servers, and low power notebooks and small form factor PCs respectively, and have been created from the ground up, according to AMD, to meet the requirements of specific form factors and usage models.
The Bulldozer core is built on 32nm technology, which includes advanced power management features, and has been designed to balance dedicated and shared compute resources, for highly compact, high core count processor designs, along with new x86 instruction support (SSE4.1, SSE4.2, AVX, and XOP including 4-operand FMAC).
The newly revealed Bobcat core is designed specifically for small mobile devices, and is capable of providing 90% of the performance of mainstream PC performance in half the area of silicon, according to AMD. The core power gating and microarchitecture are optimized for low power, enabling sub-one watt operation, along with out-of-order instruction execution for higher performance.
“In my opinion, Bulldozer and Bobcat are not only two of the greatest technical achievements in AMD’s rich history, but two of the most important for the industry as well,” said Chekib Akrout, senior vice president and general manager, AMD Technology Development
