Cisco Wireless Certification update

hello friends Cisco has announces CCIE Wireless track update. They changed  CCIE Wireless v1.0 to 2.0 means CCIE Wireles 2.0 is lunched.  So Candidates who have  their written or lab exams scheduled November 18, 2011 or later should prepare using the CCIE Wireless Written Exam Topics v2.0, and the Lab Exam Topics v2.0.

Cisco Certifications Career Poster

Cisco lunched a certification poster that provide you some guideline that where you are and where want to go, what is path to go there? Put it on your wall or desktop or keep it handy , just download it and there is  no need to visit again and again Cisco website to check your path. here is a link:-

HOW TO RECOVER CISCO ROUTER PASSWORD

This procedure is used for recovering an enable password or enable secret passwords. These passwords are used to protect access to privileged EXEC and configuration modes. The enable passwordpassword can be recovered but the enable secret password is encrypted and can only be replaced with a new password using the step by step procedure described here.


Step 1:- Attach a terminal or PC with terminal emulation to the console port of the router. Use the following terminal                   settings: 
              9600 baud rate
              No parity
              8 data bits
              1 stop bit

Step 2:- Restart /reload the Router.

Step 3:- Press Break on the terminal keyboard within 60 seconds of the power-up to abort / interrupt the boot process and  put the router into ROMMON 1 mode. Some common break keys are-

                      Break key on keyboard,    for Tera-term is Alt+B, for Hyper-Terminal Ctrl-Break or Ctrl-F6-Break

                      for Terminal Break/Ctrl-Break

Step 4:- Type confreg 0x2142 at the rommon 1> prompt to boot from Flash without loading the configuration.

Step 5:- Now type reset command at the rommon 2> prompt.The router reboots but ignores its saved configuration or Start-up config in NVRAM.

Step 6:- Type no after each setup question or press Ctrl-C to skip the initial setup procedure.

Difference Between Circuit Switched and Packet Switched Networks

Circuit Switching

In this networking method, a connection called a circuit is set up between two devices, which is used for the whole communication. Information about the nature of the circuit is maintained by the network. The circuit may either be a fixed one that is always present, or it may be a circuit that is created on an as-needed basis. Even if many potential paths through intermediate devices may exist between the two devices communicating, only one will be used for any given dialog.

Circuit Switching

In a circuit-switched network, before

communication can occur between two devices, a circuit is established between them. This is shown as a thick blue line for the conduit of data from Device A to Device B, and a matching purple line from B back to A. Once set up, all communication between these devices takes place over this circuit, even though there are other possible ways that data could conceivably be passed over the network of devices between them

The classic example of
