Cisco Systems recently took the spotlight off data center networks and put it back on the campus LAN by unveiling a refresh of all of its fixed-configuration, stackable switches. As noted in this Search Networking article, networking vendors have focused their marketing hype on data center networks and wireless LAN, while campus LAN design has been rather stable in its evolution.
“The Borderless Networks vision includes five core network services concepts that have a huge impact on the future of campus network design fundamentals: performance, video, green technology, security and mobility. Each of these will eventually find their way onto the new Catalyst 3750 and 3560 platforms; but, for now, Cisco has just three on the market: MediaNet for video optimization, EnergyWise for green technology and power management, and TrustSec for security.
“In terms of security, these new switches will have the MACsec security standard written directly into them. MACsec enables link-level, wire-speed encryption on all 48 ports, Soderbery said. Cisco’s TrustSec technology manages this MAC-based security, allowing the switches to auto-negotiate with one another.”
