ASR1006 Dual Route Processors Password Recovery - Tip

I recently ran into an issue when trying to perform dual route processors password recovery on a Cisco ASR1006
Problem
After breaking into rommon mode and using confreg to ignore the startup configuration, during the rest the ASR1006 loaded the startup configuration!!!!!!!!
Solution
So quick and simple, I pulled one of the RP and preformed password recovery running on a single RP. All went according to the Cisco documentation

http://www.cisco.com/en/US/docs/routers/asr1000/install/guide/routers/asr1_hwc.html#wp1045971

After the system running on a single RP was recovered and fully booted I waiting for 5 minutes just to be sure; then I inserted the second RP and allowed everything to sync up.

All was well again :) phew

Note: The system was previously fully functioning with dual RPs; a configuration error was made during Tacacs+ configuration which resulted in lockout.

Summary
I hit an issue recovering and ASR with dual RPs, so rather that spending hour researching, I decided very quickly to go …

Where are all the AAA and PKI solutions gone for Dot1x

More Question than answers
(This series will be based on an enterprise with >20,000 dot1x devices)

I have been looking into dot1x authentication for Wired and Wireless devices based on device identity using x.509 Certificates. While I understand PKI, AAA, PEAP and sorts I had never really had the opertunity to bring these technologies together. I quickly found out that despite this stuff being around for years, it was difficult to answer the following questions:

Which PKI solution should I use?
Which AAA solution should I use?
How to setup the PKI solution?
Does the PKI server need to be part of AD?
What if the clients are not in AD e.g. Wireless Tablets?
How do I issue certificates for devices?
How to configure the devices (wired and wireless)?
What AAA server do I use?
How do configure the rules and policies and identify clients?

What are the answers?
I am going to kick off a series here at networking-guru.net that tries to address the question above; I have limited time but hopefully I can …

Dell Latitude D830 SSD Upgrade

Slow Laptop Syndrome
I have a LATITUDE D830 : INTEL CORE 2 DUO T7500 4GB Ram from 2008, I did get a fairly high specification at the time, so it has always had pretty decent performance. However I haven't been using it for a while and when I did it seemed slow compared to my Core 5i desktop computer. (I use Windows 7 ultimate with the latest updates)

Laptop for Work
Now I might be doing a fair bit of travelling to customer sites in the near future and the last thing I want is a poorly performing Laptop, so I decide to ditch all the crap I had on it like iTunes, movies, miscellaneous software and cut back to a basic "work" PC. After all I do have iPhone, iPad and new kindle (soon) for all my multi media needs.

I purchased a "Corsair 120GB Force 3 SSD 2.5" SATA-III 6Gb/s Read = 550MB/s, Write = 510MB/s" from ebuyer.com. Now I am guessing that SATA-II rather that SATA-III on the system board, but the price difference between SATA-II and SATA-III was nothing …
