Cisco

Cisco Systems is a major network technologies company. This tag identifies general information related to the company.

CCDA

Cisco has an entry level design certification called the Cisco Certified Design Associate, or CCDA. This is similar to the CCNA in that it is a foundational certification that goes a mile wide and an inch or two deep. If you have passed your CCNA and you are looking for the next challenge, take some time to consider the available options...

  1. Specialize in an area of networking with Cisco's Voice, Security, or Wireless CCNA Certifications.
  2. Take your CCNA level knowledge to the next level and focus on the CCNP
  3. Focus on the design track, starting with the CCDA.

If you are interested in persuing the CCDA, there are some great resources to get started. First, check out the Tekcert articles section for writeups on the CCDA or on specific topics that align with exam topics. Also, check out the Exam Topics, CCO login required.

ASA/PIX Order of Operations

Cisco ASA 5505 Unboxing 9/10

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

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.

More CCNP Update Resources

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!)

Testing AAA on ASA/PIX

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

Cisco Revises CCNP Certification Track

Cisco recently revised their CCNP track to make it align with actual job requirements (such as troubleshooting problems on networks full of Cisco equipment).What do these changes mean for current Cisco Certified Network Professionals? Well, not much other than  you still get to take a 642 level exam to renew it. However, for all you non-CCNPers out there, tighten your belts and sharpen your pencils because you are in for a bit of a change.

Brocade Certified Network Engineers (BCNEs) Highest Paid

Storage has seen a huge amount of growth and interest in the more recent years. The average cost of a megabyte seems to have been halved year over year since the 80s. With intense interest in the area and businesses investing heaviliy in the technology to store precious information, there is bound to be a trained staff supporting it on the back end.

Which Certification Should I Pick?

You may be asking yourself which certification track you should focus on. If you are already in a set career path, like network engineering or system administration, then your best bet is to select something from your given area of expertise. Cisco's track for networking or microsoft's track for systems administration are rock solid.

If you are interested in taking any direction with your career or are looking for some change, take a look at certification magazines annual certification salary survey to get some ideas. The highest paid certifications are typically some of the hardest to earn, but if you really want to change your careers direction, you are bound to ride the wave with a high paying cert.

ASA SSL Clientless VPN Plugins

These plug-ins are buried so deep in the Cisco site, it took me a good hour to track them down. These allow you to add functionality to the clientless SSLVPN on an ASA through Java. These ROCK for setting up remote administration (without a full VPN) for a network.
SSH Plugin
RDP2 Plugin (supports Win2008/W7)
VNC Plugin
*Note - for the RDP2 plugin, the ASA does not have a built-in plugin type for it. You must manually type "RDP2" as the plugin type when uploading it to the ASA* - click thumbnail below for screencap.

CCNP Update: Changes in a Nutshell

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

Gives a Whole New Meaning to CatOS!

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!

Oodles of Free Cisco Tools

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).

Random Shortcut: Copy R S

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.

Bigger, Better, Faster: The ISR G2

I was on a call with someone today who said they just ordered an ISR G2 from Cisco. Huh? (That'd be my response). Wow - just looked into this; welcome to the "next level" of ISR routers:

Comparing the ISR to the ISR G2

I'm just excited about the "one IOS image" finally coming to consumer-level routers!

Cisco Updates SAFE Design Guides

I'm a little behind on this (occured a couple months back)...but Cisco has updated their famous SAFE design guides. Excellent resource:

Cisco ASA...In VMWare?!?

Now this is cool. Someone from the Phoenix Cisco Users Group gave me a link to a group who has virtualized the ASA platform. You can download a VMWare image (or self booting CD) that runs the full Cisco ASA software (fully functional).
