Host [MAC] vlan [x] is flapping between port [x/x/x] and port [x/x/x]
Hi all, I have two switches connected in cross-3750X stack into a single SW 6500., But I get the following error appears.
18w2d: %SW_MATM-4-MACFLAP_NOTIF: Host 0012.950a.9952 in vlan 10 is flapping between port Gi5/0/46 and port Gi6/0/44
What can i do?
Thank you very much¡¡.
The configuration on the port channel is that all the port must be with the equal configuration :
For example :
interface Port-channel1

Hi Guys,
Iam seeing above issue on two of my switches connected to core switch ....i know there are quite of few discussion open on same issue but mine is diff....
i see same issue on two switches connected via core swicth on same vlan ( 112)....when i do mac address lookup it says the mac thats generating this error is invalid so cant track the source of this mac....also just saw on topoogy change notification on core traced it back to originating switch which is also generating this error but dnt see any change on the switch that is generated topology change notification....prob is vlan 112 all interface on both switches conected via core are generating this message so five interfaces each .....any expert advise on how to approach it as i cant get to source port generating this as nearly five ports in vlan 112 on bloth switches generating this error. thanks

There are lots of thread discussing about this, you should do a search before creating a new post.
Anyway, this is how you approach these types of flapping:
1. Is the the given MAC flapping in the log flapping only 1 time or you see it multiple times over a reasonobly short time?
If you see it only once or once every 2-3 hours this might be not an issue worth being investigated. Sporadic one time flapping are expected in L2 broadcast domain.
If you see it often continue to step 2.
2. Identify and locate the flapping mac in vlan 125: 3270.990a.a504
Is the mac of a dual-homes server using some kind of load balancing algorithm (active/active) for which the same address is used from both NICs?
If yes, the message is not and issue but just an indication. Fix this type of LB (make it active/standby or make sure the server uses 2 different mac addresses, one per NIC) or if it is not possible leave it like this.
3. Is the MAC a the wireless NIC of a PC?
Make sure that the user was not moving from one AP to another (flapping is normal in this case)
4.
See if you have increasing TCN's and check if they are coming from the same interface.
From this point on you keep on troubleshooting STP until you find the offending link (likely going up and down) or the switch. You also need to check if STP in vlan112 is coherent with the actual L2 topology you have.

Problem
The switch generates %SYS-3-P2_ERROR: Host xx:xx:xx:xx:xx:xx is flapping
between ports? messages, where xx:xx:xx:xx:xx:xx is a MAC address.
Description
This example shows the console output that you see when this error occurs:
%SYS-4-P2_WARN: 1/Host 00:50:0f:20:08:00 is flapping between port 1/2 and port
4/39
Use the steps and guidelines in this section in order to understand and
troubleshoot the cause of this error message.
The message indicates that your Catalyst 4500/4000 switch has learned a MAC
address that already exists in the content-addressable memory (CAM) table, on
a port other than the original one. This behavior repeatedly occurs over short
periods of time, which means that there is address flapping between ports..
If the message appears for multiple MAC addresses, the behavior is not normal.
This behavior indicates a possible network problem because the MAC addresses
move quickly from one port to another port before the default aging time. The
problem can be looping traffic on the network. Typical symptoms include:
· High CPU utilization
· Slow traffic throughout the network
· High backplane utilization on the switch
For information on how to identify and troubleshoot issues with spanning tree,
refer to Spanning Tree Protocol Problems and Related Design Considerations
<http://www.cisco.com/en/US/tech/tk389/tk621/technologies_tech_note09186a00800
951ac.shtml> .
If the error message appears for one or two MAC addresses, locate these MAC
addresses in order to determine the cause. Issue the show cam mac_addr command
in order to identify from where these MAC addresses have been learned. In this
command, mac_addr is the MAC address that the error reports as flapping.
After you determine between which ports this MAC address is flapping, track
down the MAC address. Connect to the intermediate devices between your
Catalyst 4500/4000 and the device that has the problem MAC address. Do this
until you are able to identify the source and how this device connects to the
network.
Note: Because the MAC address is flapping between two ports, track down both
of the paths.
This example shows how to track both of the paths from which this MAC address
has been learned:
Note: Assume that you have received this message and you have begun to
investigate it.
%SYS-4-P2_WARN: 1/Host 00:50:0f:20:08:00 is flapping between port 1/2 and port
4/39
In order to track down how this MAC address was learned from both ports,
complete these steps:
1. Consider port 1/2 first, and issue the show cam dynamic 1/2 command.
If you see the MAC address 00:50:0f:20:08:00 in the list of the MAC addresses
that have been learned on this port, determine if this is a single host that
is connected or if there are multiple hosts that are registered on that port.
2. On the basis of whether there is a single or multiple hosts,
investigate the device:
o If there is a single host (00:50:0f:20:08:00) that is connected, check the
other port that is registered and see if the host is dually attached to the
switch.
In this example, the other port is port 4/39.
o If the host has connections to other devices that can eventually lead back
to this switch, try to track down the intermediate devices.
With Cisco devices, issue the show cdp neighbors mod/port detail command. The
output provides information about intermediate devices.
Here is sample output:

3. Establish a Telnet session with the device and follow the path of the
MAC address.
In this example, the IP address is 172.16.1.1.
Repeat the procedure for all MAC addresses that the error message reports as
flapping.
4. Create a simple diagram of the source device with that MAC address and
of the physical connections (the Catalyst 4500/4000 ports) from which and to
which this MAC address is flapping.
The diagram enables you to determine if this is a valid port and path for your
network layout.
If you verify that both ports on which the MAC address is flapping provide a
path toward that network node, there is a possibility that you have a
spanning-tree failure issue. Refer to Spanning Tree Protocol Problems and
Related Design Considerations
<http://www.cisco.com/en/US/tech/tk389/tk621/technologies_tech_note09186a00800
951ac.shtml> in order to isolate and troubleshoot this loop.
In large networks in which multiple hosts from multiple vendors are
interconnected, difficulty arises as you try to track down the host with use
of just the MAC address. Use the search utility for the IEEE OUI and
Company_id Assignments <http://standards.ieee.org/regauth/oui/index.shtml> in
order to track down these MAC addresses. This list is the front end of the
database where IEEE has registered all MAC addresses that have been assigned
to all vendors. Enter the first three octets of the MAC address in the Search
for: field of this page in order to find the vendor that is associated with
this device. The first three octets in the example are 00:50:0f.
These are other issues that can cause this message to appear:
· Server NIC redundancy problem?There is a server with a dual-attached
NIC that misbehaves and does not follow the standards. The server uses the
same MAC address for both ports that connect to the same switch.
· Hot Standby Router Protocol (HSRP) flapping?Flapping HSRP can cause
these messages to appear in the Supervisor Engine console. If you notice that
HSRP implementation in your network is unstable, refer to Understanding and
Troubleshooting HSRP Problems in Catalyst Switch Networks
<http://www.cisco.com/en/US/tech/tk648/tk362/technologies_tech_note09186a00800
94afd.shtml> in order to resolve the problem.
· EtherChannel misconfiguration?A misconfigured EtherChannel connection
can also cause these symptoms. If ports that the flapping message reports are
members of the same channel group, check your EtherChannel configuration and
refer to Understanding EtherChannel Load Balancing and Redundancy on Catalyst
Switches
<http://www.cisco.com/en/US/tech/tk389/tk213/technologies_tech_note09186a00800
94714.shtml> in order to troubleshoot the configuration.
· Host reflects packets back onto the network?The reflection of packets
back onto the network by a host can also cause flapping. Typically, the root
cause of this packet reflection is a broken NIC or any failure of the physical
interface of the host that is connected to the port.
If the reflection of packets by the host is your root cause, obtain a sniffer
trace and examine the traffic that goes to and from the ports on which the
messages have appeared. If a host reflects packets, you typically see
duplicate packets in the trace. The duplicate packets are a possible symptom
of this flapping of the MAC address.
Refer to Configuring SPAN and RSPAN
<http://www.cisco.com/en/US/docs/switches/lan/catalyst4000/6.3and6.4/configura
tion/guide/span.html> for details on how to configure a port for use with a
sniffer.
· Software or hardware defect?If you have tried to troubleshoot the
flapping message with the instructions in this section but you still notice
the issue, seek further assistance from Cisco Technical Support
<http://www.cisco.com/en/US/support/tsd_cisco_worldwide_contacts.html> . Be
sure to mention and provide documentation of the information that you have
collected while you followed the steps. This information makes further

%SW_MATM-4-MACFLAP_NOTIF: Host 3270.990a.a504 in vlan 125 is flapping between port Fa0/21 and port Gi0/1
Please suggest me how can i fixed it ?Sachin,
those are by no mean errors! they are informative messages which, in some circumnstances, can represent issues.
As I wrote in step 1, very first step is to determine how often you see a given mac flapping between 2 interfaces.
How often do you see that?
I am reiterating the concept as, according to your description, what you see can be pretty normal in your scenario.
Maybe it is worth clarifying that the message only means that a frame learned via Fa0/21 is now seen from Gi0/1. In static and stable networks traffic from a given host should always come from the same path and therefore should not be re-learned from another port. Every time a switch notices that a MAC which was previously learned from a port is now seen and learned from another one it trigeers that message as this behaviour might represent an ongoing L2 loop, but as I wrote this is not always true.
However since you have an AP connected to Fa0/21 it is likely that a host with mac 32:70:99:0a:a5:04 was connected to it for some time, and then it browsed and connected to another AP. This is why your switch started seeing traffic from that mac coming from a distribution/switch switch connected to gi0/1, as the l2 path changed.
I was not able to find the vendor of 32:70:99 as this is not an assigned OUI. Also since this is an unicast locally administered address it could besome kind of application/protocol using it.
What you have to do is
- Check in stable condition where this mac is learned from, that is following it switch by switch until you find the port. Since it comes from an AP most likely it is learned from the radio antenna of the AP. You need to check wheter this is an addressed learned over the radio or local to your motorola AP.
- Once you identify you you will be able to udnerstand why it flapped.
Having said that you will understand that the majority of your questions don't have too much sense now.. however
1. They are messages and not errors. see above why you see them.
2. Check on APs mac address table and see where that address is learned from. I don't know if your AP has some kind of mac notification feature logging all the changes. This is somethign you have to work out yourself. The focus is to first understand what is the mac address in the first place.
3. This question means nothing. If the flapping address is the mac of some kind of wireless NIC (laptop, smartphone etc.) you cannot prevent users from moving from a site to another. This is waht wireless networks are about. Still, sporadic flapping messages are expected as they just represent how the network is being utilized and you cannot fix them as there is nothing to fix.
4. The message itself has no impact. If they represent users moving from a wireless location to another there is no harm. If they are continuous and are not related to wireless networks they might indicate a L2 loop. To verify that you need to look for other symptoms which normally are associated with l2 loops: high cpu on the switches in the path, interface drops (on l2 and l3 interface, if present), increasing STP TCNs (not all the times), unstable STP topology, unstable control plane, similar logs logged in all/many switches. Some or all symptoms can occurr.
5. plenty.... google it and spend some time reading the docs you find

Port out of alarm and port in alarms on 1751
Hi There
Have a huge problem, every now and again my router loses connection "The router is a Cisco 1751 connected to a WIC-1T card" and the error messages I receive are "port out of alarm" and "port in alarm". I have no idea what this meant and my searches turned up nothing as well.
Any assistance with the meaning of this error will be appreciated

Is it possible to port a number out and port a number in without any disconnection?
I have a second line for a family member and they will no longer be on my plan. The issue is they would like to port their number but I am still under contract with that number. I'm having someone else take over the line. My question is it possible to have the Verizon number ported out and then have a new number ported in? I'm not trying to have the line disconnected as someone else will be using the line and would also like to have their number ported in.
ednice84,
Lets get these numbers ported in and out! I am sorry but if you are going to port a number out the line will be disconnected. As the port process is completely taking the number from VZW to another company it is necessary for the line to disconnect for the port process to complete. If you would like to just port the number in and have it take over the line that is currently in contract you can do that. Let us know if you have any further questions.

ThanksWe had multiple redundant links between switches, and then the servers were connected to each switch. It was a mess. I removed many of the links and left only two.
Do you have all of your SSIDs in the same VLANs across the ports? In other words, do you have it like:
guest - vlan 100
secured - vlan 105
If that's the case, and the access points are all configured this way, you shouldn't see a flapping I wouldn't think. I would verify that it's an access point in these ports that are flapping, and then work backwards from there.

Host Flapping Between Port Channel
Hi,
I have 2 VSS Pair (4X6509E) Switch. First VSS Pair is configured as Server Core and Second VSS Pair is configured as LAN Core. There is a port channel Port 10 with 4Port configured between Server and LAN Core. We have also couple Wireless LAN Controllers (5508) Connected to Server Core. PortChannel 25 from Wireless LAN Controller 1 and Portchannel 26 from Wireless LAN Controller 2. (Only 1 controller will be acitve at a time)
My issue is that am getting a MAC Flapping error between Port Channel 25 and Port Channel 10. I tried cleard the MAC entry and from ARP found the IP is LAN Core SVI.

I want to buy a mac and i am confused between macbook air 13 inch and i mac. which one should i buy
actually i am new to mac so i am confused between macbook air 13 inch and i mac. which one should i buy? i will be installing windows 2 on it..
An MBA is a portable while an iMac is a desktop and is not portable. You could install Windows on either provided each had sufficient memory installed and a large enough hard drive. The iMac is better equipped for this from the outset, but the MBA can be adequately configured if you are willing to spend the money to do so.

No Device Name and Port in UserTracking Report for Ipphones
Hello,
I'm having problems with Usertracking to IpPhones. The report provides information of usertracking IPPhone number, CCM Address, MAC, etc.. But the information in "Device Name" and "Port" (which would be connected) do not appear.
The CCM normally appear in Topology Services, and reports Usertracking EndHosts to operate normally, even in the same switches that the phones are connected.
ThanksWhat version of Campus Manager are you running ?
What version of the Call Manager do you have ?
What kind of IP Phone is this ?
Post screenshot of the problem re-run data collection and UT . Ensure that you don't have any filters in place and all subnets are included.
Do an snmpwalk from the CiscoWorks LMS server to the Cisco Call Manager and see if you can poll those values from the cli and let us know the results using the "ccmPhoneTable" ?
Get the ut.log and ani.log with neccesary debugs enabled for phones. -

Line Protocol flapping between 2 routed ports over a 1Gb circuit
Hi,
We currently have a 1Gb circuit between 2 sites that is presented to us as copper ethernet on both ends.
One end is a Cisco 4948, the other a 3750E.
Our switching connect into the ISP NTE devices.
Both our switch ports are routed ports on a P2P subnet.
The A-end (3750E) of the circuit is showing up/up
But the B-end (4948) the interface flaps constantly (up then drops after 3 seconds). The time until the interface shows up again varies between 4-10 seconds.
Throughout the flaps there is not a time when we can ping between both switches.
The B-end switch has been replaced. And the cable between the B-end switch and the B-end NTE has been tested fully.
The configuration on the interfaces are fairly standard:
- ip address
- speed auto
- duplex auto
(I've tried all combinations of speed/duplex settings at both ends)
The ISP attended the B-end NTE and reported a loss of signal from our B-end Switch. They report that a test from the B-end NTE to the A-end is successful.
What further steps could be taken to troubleshoot this?
No configuration changes were made at the time of the issue.
Is this firmly an ISP issue to investigate?
Any suggestions welcome.
Thanks,
KyleHello
i am suprised the ISP didn't investige both end on this circuit !
- Have you check physically on the Nte device for errors ( rx -tx link LEDs etc )
- powered the Nte down -chaned the cabling BOTH of ends?
- used a different port?
- performed a TDR ?
- get the isp to attend site A

7.3.2 Default Host and Ports 995 and 587
Firmware 7.3.1 broke default host completely. This problem only seems to have been partially fixed with firmware 7.3.2.
In my limited testing, while ports 22, 80, 443, and 5900 seemed to be routed to the specified default host, ports 587 (SMTP using SSL) and 995 (POP using SSL) weren't. They had to be specified under the NAT setting. (The certs are not self-signed.)
Rather than wonder which of the 65535 ports might not be working as they should under default host I just went back to firmware 7.2.1.
Has anyone had success with default host over ports 587 and 995 in 7.3.2?I think you mean 7.2.3!
Anyway, you're right, you need UB versions of your plugins to work on Intel Macs.
I believe that BFD is now UB, you need auto-tune 5 to get a UB version, likewise Guitar Rig 2. Not sure about Analog Factory. Google is your friend here. You might well need to pay for these upgrades, but see them as functional updates as well as a matter of compatability.
I can see that people might get frustrated about this, but there's no way round it. Still, it's all part of the package. And neither is it a matter of keeping your host software current, it's about keeping your host hardware up to date. Any Intel Macs need UB software. Admittedly, you could try running in Rosetta, but I reckon that the reason why your plugins won't load is because if they bothered, your system would be so slow you wouldn't be able to get anything productive done at all. Consider it an investment, the extra power from the Intel machines is well worth the cost of the upgrades IMHO... -
I have a Macbook pro 13.3 w/ i5 that has no hdmi port. I want to be able to connect the Mac to my TV set to watch Video, Photos and files from Mac to TV.
Is the Thunderbolt port similar to a display port or mini display port? Can I use thunderbolt port to connect thru a mini displayport to HDMI cable or converter?
Been trying to locate a USB to HDMI cable or converter (at a reasonable price) but all I found is a displayport or mini displayport to HDMI cable/converter.
What other options are available ?
Thanks a lot for your assistance.Thunderbolt uses a Mini DisplayPort adapter to send video and audio to HDMI. Here's some on Amazon http://www.amazon.com/s/ref=nb_sb_ss_c_2_8?url=search-alias%3Dcomputers&field-ke ywords=mini+displayport+to+hdmi&sprefix=mini+dis%2Caps%2C249#/ref=nb_sb_noss?ur l =search-alias%3Dcomputers&field-keywords=mini+displayport+to+hdmi+with+audio&rh = n%3A172282%2Cn%3A!493964%2Cn%3A541966%2Ck%3Amini+displayport+to+hdmi+with+audio

Computer short name counted twice in System Profiler
My Macbook Pro's Short Name is somehow being counted twice when I look in System Profiler. It shows (2) next to the name of my computer. Any idea how to fix this?
