Just came across this link: Navigating Cisco.com Documentation. What a fantastic walk-through!

Much thanks to Joshua Walton for forwarding this info over to me - handy reference:

====================
Packet Flow Sequence
====================
PIX/ASA - Inside (Higher Sec_Lev) to Outside (Lower SEC_Level)
---------------------------------------------------------------
Eg. Type - [Sub-Type] - Description
1. FLOW-LOOKUP - [] - Check for existing connections, if none found create a new connection.
2. ROUTE-LOOKUP - [input] - Initial Checking (Reverse Path Check, etc.)
3. ACCESS-LIST - [log] - ACL Lookup
4. CONN-SETTINGS - [] - class-map, policy-map, service-policy
5. IP-OPTIONS - [] -
6. NAT - [] - xlate
7. NAT - [host-limits] -
8. IP-OPTIONS - [] -
9. FLOW-CREATION - [] - If everything passes up until this point a connection is created.
10. ROUTE-LOOKUP - [output and adjacency] -

Some handy links I just discovered on Cisco's website for the new CCNP:

CCNP Cert Combination Tool: Figures out what CCNP exams to take based on what you have

ESIM Tutorial: A walk-through on how to work with the new CCNP question types

TSHOOT Demo Simulation: Give you an idea of the question types on the new TSHOOT exam (wow - this looks intense!)

Stole this one from the Cisco Reader Tip - very handy! Allows you to test AAA user authentication from the ASA command-line:

ASA# test aaa-server [authentication|authorization] <aaa_server_group> [host <name>|<host_ip>] username <user> password <pass>

For example:

ASA# test aaa-server authentication TACGroup username johndoe password cisco123

if authentication is successful - INFO: Authentication Successful
if authentication fails - ERROR: Authentication Rejected: Unspecified

Just putting these commands in a handy place since this seems to happen more often than I thought...

rommon #1> ADDRESS=192.168.1.10
rommon #2> SERVER=192.168.1.1
rommon #3> GATEWAY=192.168.1.1
rommon #4> IMAGE=asa800-232-k8.bin
rommon #5> PORT=Ethernet0/0
rommon #6> tftp

I recently was attempting to install CUCM 7 on an older MCS-7825 server...unfortunately, the server is old enough that it only had a CD-Rom drive (and CUCM 7 is on DVDs)...Stumbled onto this utility:

http://sourceforge.net/projects/unetbootin/

Allows you to "burn" an ISO image onto a USB stick (and make a bootable USB drive in the process). Nice! Worked well for my CUCM install, but has a million other uses too.

Okay, here's the scoop:

• CCNP will now be three exams, ROUTE, SWITCH, and TSHOOT
• Exam price will increase from $150.00 to $200.00 per exam
• ROUTE and TSHOOT courses (typically 1 week Cisco official courses) are now supplemented with e-learning material (nearly 8 hours for ROUTE and 9 hours for TSHOOT) which is exam material
• Classes / Exams are becoming even MORE real-world (TSHOOT class is 92% hands-on)
• New ROUTE and SWITCH exam is available in March, TSHOOT is available in April.
• BSCI exam can substitute for ROUTE or vice versa
  
• BCMSN exam can substitute for SWITCH or vice versa
  
• ONT and ISCW exams can substitute for TSHOOT until end of July (ONT/ICSW exams expire then...BSCI and BCMSN are no longer offered after July 31, however can substitute for ROUTE / SWITCH for their entire 3 year expiration period).
• New CCNP exams now prepare you more for the CCIE R&S
  

One of my CBTNuggets students forwarded this over to me. Freakin' amazing use of a Cisco 1900 series switch. Wish I could do something like this for my fish tank!

Okay, I've got more useless iPhone apps than I care to admit...but CBTNuggets just released their iPhone app and it's awesome. I was learning how to configure MS Exchange 2007 Storage Groups on the way to Pizza Hut last night. Nice!

...watching the demos does create quite the driving adventure though...

While randomly searching for a Cisco DSP Calculator, I came across this link with a plethora of free Cisco tools - go Brad Reese! (a fellow I commonly see in Network World magazine).

Wow - this will save me some cash when I decide to finally learn the "dark side of the force".

GNS3 0.7RC1 Supports JunOS

I recently stumbled on this...If you try to shortcut copy running-config startup-config with anything shorter than copy run start you'll get an ambiguous command error (ex: copy ru st). However, the Cisco IOS does allow you to type copy r s as a shortcut. Who knew?

...Yes...I still like wr better too.
