What does the RTD-1-ADDR_FLAP system message mean?

I ran into this very issue many moons ago. Good post by Vinay! 

By: Vinay Sharma - Cisco 
  

Introduction

What does the RTD-1-ADDR_FLAP system message mean?

Resolution

The RTD-1-ADDR_FLAP error message indicates that a MAC address is moving consistently between different ports. This error message is only applicable on the Catalyst 2900XL and 3500XL switches. 

If users move from one Access Point (AP) to another and the MAC address shows up on a  different switch port, the error messages are displayed. These messages do not necessarily mean that there is a problem. They are displayed for informational purposes only.

It is part of normal operation for a  switch to re-learn the MAC address every time it is seen on a different port. This action always generates this message. The RTD-1-ADDR_FLAP system status messages should not necessarily be considered errors,  particularly on ports where there are APs attached.

For example, if there are APs attached to ports 3/4 and 3/5, and clients associated to those APs are roaming back and forth between the two APs, the MAC addresses of the clients are truly moving back and forth between those two switch ports. The status messages are accurate, and there is no cause for alarm.

Additional Information

Error Message

RTD-1-ADDR_FLAP [chars] relearning [dec] addrs per min

Explanation

Normally, MAC addresses are learned once on a port. Occasionally, when a switched network reconfigures, due to either manual or STP reconfiguration, addresses learned on one port are relearned on a different port. However, if there is a port anywhere in the switched domain that is looped back to itself, addresses will jump back and forth between the real port and the port that is in the path to the looped back port. In this message, [chars] is the interface, and [dec] is the number of addresses being learnt.

Recommended Action

Determine the real path (port) to the MAC address. Use the debug ethernet-controller addr command to see the alternate path-port on which the address is being learned. Go to the switch attached to that port. Note that the show cdp neighbors command is useful in determining the next switch. Repeat this procedure until the port is found that is receiving what it is transmitting, and remove that port from the network.

BUG CSCua29504: Upgrade that code if you want Windows 8 to work! #CISCO # WLC

This is from Cisco CSC 

Microsoft will launch Windows 8 in late October. Along with a slew of other features, it will be among the first to support the 802.11w standard to protect Management Frames for client devices on Wi-Fi networks.

Customers running old Cisco unified releases (between 4.2 to 7.2) in local, Flex or mesh mode will run into an interoperability bug (CSCua29504, to be exact) that prevents 802.11w enabled clients from connecting to a Cisco WLAN with Management Frame Protection (MFP) enabled. This bug does not affect customers running autonomous access point deployments or customers running Cisco unified releases older than 4.2.

What are the possible solutions for you?

1. Please upgrade your production environment to one of the following releases, which will interoperate with Windows 8.

  • 7.3.101.0
  • 7.2.111.3
  • 7.0.235.3

2. Roll back to pre-windows 8 drivers as identified in the Microsoft Knowledge Base article.
3. Fall back to TKIP
4. Sign up for a beta release for Cisco’s upcoming feature release 7.4 (beta available now!) that supports the 802.11w feature in local mode.

What is 802.11w ?

 802.11w is an IEEE standard based on Cisco’s Management Frame Protection(MFP), a feature that was first supported on autonomous access points in release 12.3(8)JA in 2006 and in the unified release 4.0.155.5 in 2008. 802.11w isn’t a new standard. IEEE ratified the 802.11w standard in 2009, however the adoption has been slow to date, but that is expected to change with Windows 8.

The WFA has announced that it will position the Protected Management Frame interoperability certification program as a feature update to its Wi-Fi Protected Access(WPA2) program.

Why do I care about 802.11w ?

I joined Cisco Wireless Networking Business Unit (WNBU) early 2006 as a Product Manager for Autonomous Access Points and the first software release that I managed was the 12.3(8)JA. One of the coolest features in that release was a Cisco innovation around protecting management frames. As many of you may know, 802.11 frames such as Authenticate, De-authenticate, Associate, Dis-associate are sent in the clear (a.k.a. in an unsecured manner). This could allow a potential attacker to spoof management frames from a valid device and run Denial of Service (DOS) attack by sending de-authenticate/disassociate frames.

When MFP is enabled, the sending device adds a cryptographic hash to create a message integrity check (MIC) and embeds that within the Information Element (IE) of every management frame. Thus when another device in the network receives the frame, it is able to verify that the authenticity of the source. In case a single invalid frame is received on the network, it will be dropped, as well as, an Intrusion Detection System alert will be received -this means zero day protection!

What about clients that don’t support 802.11w ?

There are two components to Management Frame Protection:

-         Infrastructure MFP: When the wireless Controller and Access point infrastructure support the 802.11w capability, any frames from a hacker masquerading as an infrastructure AP and attempting to communicate with other APs will be dropped.

-         Client MFP: When a client ALSO supports this feature; it is able to secure communications with the infrastructure. This means any frames from a hacker masquerading as an infrastructure AP and sending disconnect messages to the clients will be dropped.

So what’s the bottom-line?

To enable that your network is ready for 802.11w and Windows 8 ensure that you are running the latest Cisco Unified releases in your wireless controller network.

BUG CSCtt38270: 7925 sometimes takes 1+ second to respond to WPA M1 key message

Heads up if you're having wireless voice issues with 7925 handsets with WPA2/PSK. Problems with roaming, gap in voice bug.

7925 sometimes takes 1+ second to respond to WPA M1 key message
Symptom:
A wireless phone call may experience a voice gap of 1.5 - 2 seconds when it roams if using WPA2-PSK.

Conditions:
7925G is configured to use WPA2/AES PSK.

Workaround:
Configure some key management method to avoid performing a full WPA2 key exchange
at each roam time. For example, EAP with CCKM, or static WEP.
If using PSK, then reducing the WPA key retransmission timeout (e.g., on a WLC,
via "config advanced eap eapol-key-timeout 250", may ameliorate the problem
somewhat (e.g. bring the outage duration down from 2.5 to 1.7 seconds.)

1.4.3ES.1 containing the fix for CSCtz48689 may be helpful as well.

Further Problem Description:
A wireless packet capture, or a "debug client" on the WLC, will show that the WLC/AP
transmit the M1 key message to the phone (and the capture shows that the phone ACKs
it), but the phone does not send its M2 key. So the WLC/AP have to retransmit the M1 key,
till finally the phone responds.

WILDPACKETS -- GESTALT IT #WFD3 #WILDPACKETS

 

When attending a field day event it’s a challenge to listen, take good notes, tweet and do a blog post all in a matter of 2 hours. Sorry, I’m good, just not that good! 

 

Wildpackets

My interest was peaked when I heard Wildpackets was a sponsor for #WFD3. Wildpackets was one of the first commercially supported wireless sniffier products available. Lets face it, most engineers didn’t understand the 802.11 frame structure back in 2002. A lot of the captures were greek to many engineers, including myself. I was an early adopter and used what was then called, Airopeek. 

Wildpackets offers a suite of application software (and appliances) that focus around layer 2 packet analysis, both on wired (802.3) and wireless (802.11). Our WFD event focused on and what I believe is their most important product, OMNIPEEK. 

Omnipeek can be very intimidating at first, but once you get comfortable with the interface the other bells and whistles await you. And let me just tell you, there is a wealth of bells and whistles.

The Wildpackets team shared with the WFD delegates their humble beginnings and later a video about a fiery blaze that destroy their office in 2002.  We then moved on to the tech stuff!

Jay Botelho did an overview of Omnipeek. Jay shared with the delegates how to use Omnipeek, put it into sniffer mode and how to conduct a multi channel capture. We then walked through a wireless capture briefly and discussed other rich features (watch the below video to get your Omnipeek fix). Jay also shared some of the other robust features like reporting, graphs and analysis tools, which are built into Omnipeek. We also looked at our first 802.11ac capture. It was my first peek at 802.11ac. 

I understand, Omnipeek support for 802.11ac will be in released in its next release in coming weeks. 

You can read an article about the Wildpackets fire here: http://www.internetnews.com/wireless/article.php/1433881/WildPackets+Survives+Fire.htm

 

Wildpackets Advantage

The Wildpacket advantage is simple.

Coming from my personal experience, Willpackets’ Omnipeek is the best commercially offered wireless sniffer on the market today. It is well developed, packed with features and well supported. It drives information to the wireless engineer and displays it in a manner that is intuitive and accurate. A wireless engineer can capture 2,3,4 or more channels simultaneously aiding in quicker fact gathering. To the untrained eye, Omnipeek has built reports and graphs that will bring blaring issues to the surface. 

All of these features do come at a cost. And if you are a consultant or work for a large enterprise it can easily be justified. 

If you ever need customer feedback and or justification for Omnipeek in a large enterprise, email me I will be happy to share my experience. 

My take away

Next time you’re troubleshooting a wireless issue at the frame layer and you’re using something other than Omnipeek you’re missing out on all the other rich features that only Omnipeek offers.

Also, take notice next time you are reading a 802.11 technical book or looking at published material that displays a 802.11 capture. Pay very close attention, its very likely you are looking at a capture done in Omnipeek.  

In closing, one other important take away I learned at Wildpackets is just how much they value their employees. Thats a company I want to do business with. 

Captures

Wildpackets provided us 802.11ac and 802.11u captures. Links to these captures are below:

Wireless Tech Field Day Starts today @ San jose #WFD3

I am very humbled to be asked back to participate as a delegate in WFD3, presented and hosted by GESTALT IT.  WFD3 <Wireless Field Day 3> brings some new vendors and new delegates together for yet another event filled wireless geek gathering.  “ GESTALT IT Independent Experts United “ 

WFD is an event where industry users <experts in some cases> come together with wireless vendors to discuss wireless, technology road map and issues and features with the respected vendors. This allows vendors first hand experience with users who may be using their product already, whereby providing valuable feedback or in some cases introducing their product to users for the first time.

WFD is also a large social media event. WFD has hundreds and sometimes thousands of like minded folks who will follow along and sometime paticpate in twitter feeds from each event. 

This particular WFD3 brings together both hardware and software vendors. 

Sponsoring Vendors 

I would like to personally thank Aerohive, Aruba, Cisco, Meraki , Metageek and Ruckus for their repeated support and sponsorship of WFD. I would also like to thank and welcome TabazaWildpackets and Juniper who are new sponsors.

 

                         

        

 

WFD3 Delegates

WFD brings together like minded individuals who share common interest in technology, in the case of WFD, lets just say, it’s wireless geek week at its best! Each delegate brings a unique real world experience and perspective. Some delegates work for VARS, others are independent consultants or end users. 

 

WFD3 delegate notables:

 

Blake Krone - CCIE Wireless

Keith Parsons -  CWNE, Wifi Industry Expert and mentor to many of us 

Gregor Vucanjnk - CWNE, Recently minted <like last week recent -CONGRATS>

Vendor Questions and Perspective

As a wireless architect for a large and world renown healthcare system I will be focusing my questions and comments around healthcare specific WiFi. WiFi in healthcare presents very unique challenges. Real time applications requiring wire like connectivity and reliability. Large HC systems can have thousands of WiFi devices from COWs, mobile desktops, tablets, handhelds, scanners, RFID tags and the list goes on. 

I am interested in how each hardware vendor is handling 802.11u, 802.11w, BYOD, MESH, 802.11ac, 802.11r and especially the APPLE explosion in Healthcare. These are hot buttons on my plate as well as many other Healthcare WiFi professionals.   

  • Healthcare is facing tighter budgets due to recent reform. Health Systems need to be cost aware when making purchases and get more bang for the buck. How are vendors positioning their product to compete in the current Healthcare market.
  • BYOD and on boarding challenges and cost associated. Healthcare is leading the charge with BYOD. The sheer volume of WiFi devices contained within most hospital systems is larger than the population of some towns!
  • How does Cisco’s new HA license and vWLC change the game ?
  • Built in Rogue and wIPS systems - most are clunky and dont work well and have a cloud of mystery behind them.  
  • How are vendors supporting the APPLE explosion. Any new features or roadmap to better support troubleshooting and making up for APPLE deficiencies. 
  • Are vendors partnering with Apple to provider a better WiFi user experience. Looking for vendor perspective on the Apple road map, what are they doing with Apple to make our life easier
  • PCI and HIPAA any new or existing features that allow admins to pull relevant data. Does this cost extra ?
  • Vendors take on controller vs. controllerless  platforms<We know where Aerohive stands :) >
  • How secure is WiFi “cloud” computing - Vendor perspective?
  • Remote Office Solutions - Vendor perspective ?
  • 802.11ac roadmap 

I am a BIG fan of Wildpackets. There is no better wireless sniffer in the world. Excited to meet the wildpackets team. 

Never used Tanaza, very interested to hear about their offerings. 

My friends, we are in a middle of a compelling wifi convergence. Never before has WiFi seen the attention or the publicity like it has in recent years. WiFi is a moving force like no other, you cant stop it nor can you contain it. Most of the population on planet earth knows what WiFi is. Just grab on and enjoy the ride!
