Today, Cisco announced a little something to help clear the way. The world’s largest maker of networking equipment unveiled a new member to its growing family of routers custom-made for the Information Age. Known as the Cisco Aggregation Services Router 9000 (ASR 9000), the company says the machine has six times more capacity and is four times faster than any other router in its class. In fact, the company says, the brawny router is more powerful than any other competing router, period.

The ASR 9000 also includes new technologies for proactively managing notoriously challenging video signals. It makes corrections and ensures picture quality for ultra-clear high-definition TV and other video services, Cisco executives say.

Last week at 3 A.M I received a call from our Help Desk, stating our applications are not running in one our departments. I logged remotely to our Network and try figured out what is problem. Upon carefully looking at the logs in our Cisco 6513 core Switches I figured out a duplicate IP address is created which happens to be the Standby IP address for the Core Switch for HSRP.
I figured out the PC by looking the at mac address generated in the log and closed the network connection for that particular PC and the problem was solved.
If you face similar problems its better to change the HSRP Standby IP address in Core Switches and then try figure out the infected PC. Once the PC is figured out close the network connection and make sure the Trojans are removed. Upon cleaning the infected PC you can reconfigure the HSRP Standby IP address to the previous one.
Once I get the complete solution to fix this problem I will post it.
Dear Friends if you are preparing for CCNA 640-802 certification it would be great to remember the popular applications as well as the TCP/UP ports.
You should at least be aware of some of the applications used to manage and control the network.
In which slot shall we install the Supervisor Engine in Cisco 6500 Series Catalyst Switches -Series1
Dear Friends the Cisco 6500 Series Catalyst Switch comes in different models like Cisco Catalyst 6503-E Switch, Cisco Catalyst 6506-E Switch, Cisco Catalyst 6509-V-E Switch, Cisco Catalyst 6509-E Switch and Cisco Catalyst 6513 Switch. But is there any specific slot assigned in these switches to install the Supervisor Engine SUP720? Yes there are specified slots assigned to install the Supervisor Engine SUP720 in any of the Cisco 6500 Series Switches.

Now let’s find out these details,
The Cisco Catalyst 6503-E Switch comes with three slot chassis. In the Cisco Catalyst 6503-E Switch the first two slots are reserved for Supervisor Engine SUP720, if you have one Supervisor Engine SUP720 then you can install the Supervisor Engine SUP720 module either in slot 1 or slot 2.
I will cover these details for other models in my next post.

Recently I came across new Network Management software, which happens to be good NMS systems I have ever seen. Always I try to follow and find the latest technological developments and I always love to test the trial version of latest Network Management Software’s from any vendor.
Though Packet Trap is a new but it seems the team posse’s great experience in building Packettrap pt 360 tool suite.
Packettrap pt 360 tool suite is windows based Network Management as well as Diagnostic tool. The best thing about Packettrap pt 360 tool suite is its download size and it never consumes more memory resources in the PC. Packettrap pt 360 tool suite is a light weight application and can run on almost any windows XP/ Vista machine with minimum configuration requirements.
The first look of Packettrap pt 360 tool suite is very impressive and it’s too simple to use with easy navigation and menu options. The dashboard has nice looks and more over it come with drag and drop components.
The Packettrap pt 360 tool suite is quite useful to Cisco Network Administrators as well as good tool for Windows Administrators. I would strongly recommend Packettrap pt 360 tool suite , just have a try. One more good news from Packet Trap is their PT360 Pro Network Management Diagnostic Tool Suite is free forever. So make use of this opportunity.

In the first series we just started to know about SNMP Version 3 and we just created a SNMP View called ITKEView. Now let’s proceed further and create a SNMP group called “ITKEGroup”. This group is granted an access to view “ITKEview” which we created in the previous step.
ITKE(config)# snmp-server group ITKEview v3 auth
Finally let’s create a SNMP username called “ITKEuser” and grant it an access to the “ITKEGroup” that we created in previous step. We will provide an authentication password as well as privacy password which will serve as an encryption key for the SNMP protocol. ITKE(config)# nmp-server user ITKEuser ITKEGroup v3 auth md5 ITKEpass priv des56 ITKEpass2
