Cisco to Acquire Pure Digital Technologies

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

During this economic crisis Cisco is brave enough to acquire Pure Digital, the makers of the popular Flip line of portable video cameras for $590 million in stock. Cisco will also pay out $15 million in retention incentives for Pure employees who stay on with the new company.

More than 2 million Flip video cameras have been sold in the U.S. to date, and the move will expand Cisco’s consumer market presence with what is essentially, a high-end toy.

“The acquisition of Pure Digital is key to Cisco’s strategy to expand our momentum in the media-enabled home and to capture the consumer market transition to visual networking,” said Ned Hooper, senior vice president of Cisco’s Corporate Development and Consumer Groups. “Pure Digital has revolutionized the way people capture and share video with Flip Video. This acquisition will take Cisco’s consumer business to the next level as the company develops new video capabilities and drives the next generation of entertainment and communication experiences.”

Don’t Panic for ICND 1 Simualtion questions.

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

One of my colleagues went for the ICND 1 (640-822) exam and he failed to pass the exams with a small margin. He got few simulation questions, in which he was suppose the find out the IP address for the router interfaces connected in the topology provided. The show running command was disabled, he was suppose to use alternative IOS commands to determine the IP address assigned to the router interface.

 

In this scenario don’t panic,  the best command to determine the IP address assigned to interface s in any router is “show ip interface brief” or Show ip interfaces. Here is the sample output of these commands

 

ITKE-DAC-3745R01#sho ip interface brief
