• Petr Lapukhov described the differences between shaping and policing, the Unidirectional Link Detection (UDLD) technology and the PPP IPCP subnet mask negotiation. Obviously he had a highly productive week :) ... or maybe the shakeups in the CCIE training market result in more high-quality content? Hat tip to Ethan; you've made me look up a word in the English dictionary; a rare, but interesting and pleasurable event.
• Jeremy Stretch documents how you can turn a Catalyst into a totally transparent switch. Fantastic solution for lab environments. He also found a way to generate IOS type 5 passwords (enable/username secrets) on a Linux workstation.
