Brad Reese on Cisco: Nortel chief flying in corporate jet as company files for bankruptcy protection
Yours truly was totally shocked to learn that Nortel CEO Mike Zafirovski was still using a private jet, especially six days after Nortel filed for bankruptcy protection. As the company lays off thousands of workers, halts salary increases, institutes a hiring freeze, and confirms laid off Nortel employees will not be receiving their severance payments because of the bankruptcy filing, Zafirovski continued to use a private jet (often it appears to commute between a home and his office).

Michael Morris From the Field: Taking a closer look at the Cisco ASR 1000 Series
Even in a down economy we are getting ready to build a new data center. This data center will be a showcase virtualization design using the Nexus 7000 and Nexus 5000 series switches. However, one of the key parts of this new data center, other than the internal LAN, is the WAN connectivity. This data center will be our DEV/TEST/STAGE/DR data center so we will be copying large amounts of data from our production data center to the new facility.

Jamey Heary: Cisco Security Expert: PIX to ASA Configuration Migration Tool, time is running short
Ever since Cisco announced the EoS/EoL of the PIX customers have been migrating to the ASA platform. The configuration migration is very straightforward but to make it even easier Cisco developed a free Migration Tool. I’ll take you through how this very simple tool works.

Wendell Odom's Cisco Cert Zone: Does the job market push us towards multiple-CCxP?
Today I'll wrap up this thread of posts rambling about the job market. The last two such posts generated some good discussion and informal stats that I found interesting - particularly on the possible danger to CCIE's - and sparked another couple of survey's that I'll list today. I'll move on to something different next post, so if you wanted to comment on the job market stuff, here's the last blogspot on this topic for a while.

Dennis Hartmann on Cisco Unified Communications: The QoS Expedited Forwarding (EF) Model
The assured forwarding (AF) model is used to provide priority values to different data applications. The Expedited Forwarding (EF) model is used to provide resources to latency (delay) sensitive real-time, interactive traffic. The EF model uses one marking -- DSCP 46.

Cisco Knowledge Share with Avner Izhar: Is my network healthy? The Macro level using SNMP
In my previous post I explained how to use Wireshark (or any other sniffer) to get a basic understanding of how your network performs. This does not require any knowledge of the current addresses or network devices, which makes it a good starting point. With that being said, it’s a very limited starting point since in a switched environment; you will only be exposed to the traffic which is in the vlan that you are connected to. In that vlan you will only see broadcasts and multicasts.

Jimmy Ray Purser: Networking geek to geek:GSM hacking - the next big thing
I was asked by one of dudes at my monthly hackers meeting if I have been hacking GSM lately. I told them, no, I not really interested in cell phone technology plus the equipment to monitor 850MHz and 1800MHz to gather enough info to be useful to find a hole to exploit is too much for me to expense and much more then I wife would notice missing. He told me, no gear is required to find a hole, just use a pencil.

Scott Hogg on core networking and security: Cisco IPv6 Support Comes Standard
I wanted to share with you something that I have observed in the recent release notes for some of the newest Cisco IOS versions. I am realizing that more and more IPv6 functionality is being developed and integrated into the latest versions. Recently I was reading some Cisco IOS release notes and I have noticed a lot more frequent mention of new IPv6 features. I recognize that not many people sit around and look at release notes for Cisco IOS anymore. I got in the habit of reading these when I was studying for my CCIE as I wanted to anticipate what they might throw at my on the lab.
