Cisco Enterprise Wireless Mesh

So I finally tested out the "Enterprise Wireless Mesh" by converting a 1242 into a Mesh Access Point. It wasn't too difficult but there were a few catches:

For starters, you obviously must have a 1242 registered to a controller that supports enterprise mesh. Currently 4.1.192.22M (Mesh)is the recomended version.

After the AP is registered, make note of both MAC Addresses, which is obtained from the details of the registered AP.

By changing the AP mode to Bridge, the AP will reboot with the Mesh code.

And there you have it, a Mesh 1242....

But not so fast. If you have any experience with the outdoor Mesh AP's, you know you have to add the mac address to the mac-filter on the controllers (Security > AAA > Mac filtering). You need to do this with the 1242 else the mesh AP, even though it is wired, will not associate with the controller. Specifically, you need to add the Base Radio Mac.

There you go, AP should register again and be able to support other MESH access points.


I had a few problems getting a 1522 to register, but I didn't change anything. It just started working about the time I had finally given up hope.


Now I have an issue using the 1522 Power Injector network in port as a link to a remote client. More on this when I fix it.

"CCNA Security/Voice/Wireless"

Cisco has finally created
Three new associate tracks
CCNA Security and Voice
Also the Wireless Cisco lacks

The best thing about this Cert
Is only the one exam to take
So specialize your career
A new title you can make

To get the Professional level
After getting the new CCNA
You still have up to 5 more exams
But these will pave the way

If it is Wireless you pursue
There may soon be a CCWP
And rumor even has it
Of a Wireless CCIE

Unofficially Confirmed - Wireless CCIE

So I've been doing some research relating to the CCNA Wireless and I stumbled on this article at Internetwork Expert - CCIE Blog.

They go on to say:

"After speaking with multiple Cisco employees within the wireless group, the Wireless CCIE has been confirmed. Beta candidate registration should begin this fall, along with a blueprint release. Beginning early 2009 the Wireless CCIE beta testing will begin! As of now, topics of the test are expected to cover all aspects of wireless from design through implementation including the implications of security, routing and switching and voice technologies. Check back often for any additional information!"


So there you have it. Looks like there really is going to be a CCIE Wireless afterall.

More on the new CCNA Certifications

Do you think that the new CCNA certifications are a sign of what is to come? Will the CCNA Voice soon be the prerequisite to a CCVP? CCNA Security for the CCSP?

What about Wireless? Cisco has no formal career certification for Wireless. The last word I received on this topic was that Wireless is incorporated in the CCNP Track. However, if Cisco is able to create an independent associate level certification for wireless, do you think that a CCWP may be on the way? Or even a CCIE - Wireless?

Everything I read is that Wireless is going to become more important as the years go on. Don't you think that if Voice/Security/Service Provider can all have Professional Level tracks, then Wireless deserves one too? Storage Networking even has its own CCIE Track. The wireless product line and feature set that Cisco has to offer is more than enough to warrant a professional level certification.

Wouldn't it make sense for Wireless to be valued as an independent skill. Hopefully this CCNA Wireless certification is the first step in right direction.

Supplemental CCNA Certifications

So it has come to my attention that Cisco has released three new certifications as a supplement to an active CCNA. The certifications and related information is linked below:

CCNA Security
Course: IINS - Implementing Cisco IOS Network Security
Exam: IINS 640-553

CCNA Voice
Course: IIUC - Implementing Cisco IOS Unified Communication
Exam: IIUC 640-460

CCNA Wireless
Course: IUWNE - Implementing Cisco Unified Wireless Networking Essentials
Exam: IUWNE 640-721

Cisco Wireless Mobility Troubleshooting

The following debug commands for the mobility aspect of Cisco Wireless LAN Controllers are useful for troubleshooting mobility problems:

debug mobility directory enable
debug mobility handoff enable
debug mobility keep-alive enable


I'll touch back on this topic later when I have more time and go in to detail about my current implementation and how these commands have been useful for troubleshooting problems I've had in the past.

Cisco Enterprise Wireless Mesh License Information

I did not touch on this topic earlier but I have finally found official information about the licensing structure of the Cisco Enterprise Wireless Mesh product. Previously, it was assumed that licensing would be $500 per AP based on that EWM Q&A sheet that Cisco had. However, when I went to purchase said license, I was informed that it had not actually been created yet.

That has officially changed. No longer is licensing $500 per AP. You now license your controller based on it's maximum AP count (12/25/50...). Now I originally thought that meant I would be paying $500 25-times even though I only needed about 4 licenses. However, it turns out Cisco did a good thing here. The licensing structure is actually something as follows:

AIR-AP-LIC-M-12 12-AP = $750
AIR-AP-LIC-M-25 25-AP = $1500
AIR-AP-LIC-M-50 50-AP = $2500

Looks like I am making out with less cost than anticipated.


Licensing is actually not currently enforced so you do not need the license to make the technology work. However, I am under the impression that by version 5.2 of the controller code, the mesh chain will roll back into the primary release and will be an enforced license.

More on this later.

"Enterprise Wireless Mesh" - Short Poem

Enterprise Wireless Mesh
Has a nice ring to me
I believe in the technology
But if it works, we'll soon see

The cost-savings are great
There really is value here
But without the reseller's push
The customer doesn't know to care

Wireless is simply amazing
So listen up my friend
Plan your network wisely
Know that it's potential has no end

Cisco Enterprise Wireless Mesh

So next week I will be attempting to upgrade our Cisco Wireless Lan Controllers to what Cisco is calling the Enterprise Wireless Mesh (EWM). It is now possible to convert indoor Access Points (AP1131AG and AP1242AG) into Mesh Access Points and with this, I am going to be using a few 1242's as my wired connection for a few Cisco Mesh 1522's outside the building.

The design is rather simple. I'm adding an antenna to the existing A-radio on these access points that will provide connectivity to external Mesh Access Points. The initial design, which lacks any redundancy, called for a 1522 to be installed to the roof of the building. My design not only saves the cost of an additional 1522 Mesh Access Point, the installation cost-savings more than covers a few antennas on existing Access Points.

I'm really thinking this Enterprise Wireless Mesh system has good marketing potential. Cisco must not be pushing the technology yet since I was the first to tell my reseller about it.

"Wireless is the future"

"Wireless is the future"
Didn't you hear?
"No more cables
to run anywhere"

Or so I was told
A few years back
To this day I swear
They were on crack

The design was simple
Access Points up above
People would rejoice
"To IT with love!"

But that was all forgotten
The day it didn't work
Some RF Transmitter
Had a little quirk

For hours I searched
The interference was great
People started calling
"To IT with hate!"

Our time is expensive
More than a cable will be
Run those cables everywhere
So that IT will love thee

"Again I am late"

I walk into the office
About ten minutes after Eight
I think to myself
"Again I am late"

Several lights were still off
Almost no one was there
I got away with it again
Not that they really care

It is amazing to me
I get away with being late
But I live an hour away
Inevitably, it is my fate

So I sit back and relax
Pretend that work gets done
Next thing that I know
The clock shows thirty untill One

I have no clue what I did
For that half of a day
But I'm hungry now
"Whats for lunch?" I say

We come back from lunch
Usually around two
Only 3 hours left of work
I can not start anything new

So I pass my time wisely
The Internet I roam
Soon the clock strikes Five
And I'm on my way home

"It all starts here"

It all starts here
I will try to blog every day
Things should get interesting
As I blog in a unique way

For I am an IT Engineer
Welcome to my mind
I have no writing talent
So please, be kind

The topics you will read
All pertain to what I know
Some might be funny
Some might not flow

I will try to do my best
So please have no fear
With my unique take on things
It all starts here
