Where's David?, 11/08/07: Jim and Steve are old enough to remember when the Goliath that is now Cisco had several viable competitors.

Preliminary deal signed for African cable system, 11/06/07: The e-Africa Commission has signed a memorandum of understanding with 5-P Holdings to construct a $2 billion undersea cable system planned to encircle Africa with connections to Europe, South America, India and the Middle East. Cisco Discovery Protocol: Cisco Subnet blogger Raj Tolani discusses, "Cisco routers and switches use Cisco Discovery Protocol (CDP). Some would argue that CDP doesn’t follow some security recommendations because it gives away some critical information about your network devices." LAN switch security: What hackers know about your switches with Cisco's Christopher Paggen: Contrary to popular belief, Ethernet switches are not inherently secure. Security vulnerabilities exist all over the place. Did you know that there are vulnerabilities in the control plane protocols like STP and CDP? There are holes in the data plane protocols too. Christopher Paggen is prepared to tell you how to avoid these problems. Paggen is a technical marketing engineer for Cisco focusing on high-end firewalls. Join us for a live chat Tuesday Nov. 13 from 2 p.m. to 3 p.m. EST, where you can ask him about configuring and securing switches, firewalls or anything else you want to talk about.
