Implementing Cisco Switched Networks (SWITCH)admin | Friday, July 9th, 2010 | 5 Comments »
This is a review of Implementing Cisco Switched Networks (SWITCH) Foundation Learning Guide. Written by CCIE’s Richard Froom CCIE# 5102 and Erum Frahim CCIE# 7549 and Balaji Sivasubramanian.
This is an excellent book on switching fundamentals. It clearly explains VLAN’s, how and where to use them. How the old 80/20 rule is now 20/80. Security topics regarding VLAN’s, DHCP snooping, port security, PVLAN’s and much more. The authors go deep into each topic and have a great way of explaining them while highlighting the important facts.
You pick up little tidbits like ICMP redirects being turned off on HSRP enabled interfaces, or the maximum number of supported VLAN’s via ROAS (router on a stick) is 50, or that the number of SVI’s isn’t directly proportional to the number of VLAN’s supported on your switch. Who knew?
These are the kinds of info that makes this book a gem, and I think going to be an extremely popular book. I have other switching books and they all seem to just go through the motions.
I think switching and layer 2 in general are underrated. Layer 3 and routing always seems to get the limelight. But you need a properly working layer 2 for layer 3 to function. If this book isn’t on your bookshelf, get it!
If you think you know everything about VLAN’s, or PVLAN’s or VACL’s, this book might teach you something new. There’s also a kindle version that’s about $5 cheaper than the hardcover.
Although it’s written to follow the 642-813 format, this shouldn’t be passed over if you’re not studying for the certification.
