Duplex Mismatch
We recently replaced our T1 and 2600 router with a service from AT&T called Optiman. AT&T has fiber from the outside into a 24 port Catalyst 3550 switch in the MPoE of our building. Cat 5e is running from the MPoE up 5 floors to our server room where it connects to FE1/0 on our 2811 router.
I've enabled QoS on FE1/0 and we cannot seem to get a reliable traffic flow up and down. AT&T has tried to set the interface we're connected to on the 3550 to Auto and Full. Connectivity between our 2811 and the 3550 in the MPoE only seems to work when I hard set FE1/0 to half duplex 100.
Any thoughts on why setting both to 100 full doesn't seem to work?
The cable length is quite likely going to cause you problems, either due to timing or signal (noise or attenuation) issues.
You definitely want to be running it at full duplex, you'll get collisions on a link this long.
As to why it works in half/100, I've seen that many times it is the default fallback duplex/rate when the device has no idea what's going on. Something is is not right, but half/100 you get link up. However once your traffic rate goes up, watch the error rate climb too!
It sounds like you have new equipment, perhaps temporarily put something else inline just to rule it out? The link may be ok, you may just have a bad port. As your running long lengths, the port may be normally ok, but not good enough for this extreme case.

WLC 5508 duplex mismatch error
Hi I've got a WLC 5508 connected to a Catalyst 6000 switch. In the switch I've get a CDP duplex mismatch error every 30 min.

Duplex mismatch between N7k and 5508
Hi All,
I met a duplex mismatch issue in our new DC.
The port configuration on the N7k and controller is the same as in other DC
Only difference is version of the NxOS on the N7k.
On N7k 5.2(1) works
On N7k 5.2(7) i get below logs :

How can i fix this issue ? Ports are set up and show the same - 1000 / Full
the messages are annoying as loggs are almost full of them.
Thank you in advanceHi Matthew,
The issue is related to bug -> "CDP duplex mismatch when using LAG on 5508 & 8510 WLC” (CSCuc94082)
The fastest way to solve (workaround) this is disable cdp on the controller by executing following command: config cdp advertise-v2 disable
Hope this helped you

Hi all,
i am using cisco LMS 3.2 as when we run the Discripencies Report we get the
Error of LINK DUPLEX MISMATCH....
Kindly guide for the same....
This link has ports with mismatching duplex.

Technical Support: http://www.cisco.com/techsupport
Port GigabitEthernet0/1 on device MKT_3 with mode full-duplex
But when i check the configuration of both switches it shows as FULL DUPLEX for the above....
Kindly guide how to resolve the above error....This is a known issue with ports set to auto-duplex. Since the switches do not reflect the current operational duplex, LMS does not know if the port negotiated to full or half. In that case, it presents the warning so you can investigate. Once you've confirmed the duplex is correct, you can acknowledge the discrepancy.
If you upgrade your switches to 12.2(55)SE, then the switch will report the operational duplex, and this discrepancy will go away on its own. The bug that fixed this was CSCtc12593 -
Duplex Mismatch when connecting ip phone with 2950 switch
When I connect my Cisco IP Phone 7960 with 2950 Switch (any access port within voice vlan), I get the message on Port duplex mismatch but the phone works properly.
From my switch the speed setting is 100/Full but from the Phone its Auto.
My Question is when I try to change duplex settings from Phone, it doesn't gives me any option instead only one option available to save so kindly someone tell me the best way to fix this from Phone or do I have to change the duplex from switch to AUTO ?Thanks but When I connect with my Cisco 2950 Switch, I can see the weird kind of language as per my attachment.
It wasn't yesterday when I first configured from scratch but just seen today.
Switch is working good with Cisco IP phone connected with it. -
Hi
Can someone explain the following to me please.All our ip phones are deployed with their settings pc/sw config as auto/auto. Desktops are all on 100fullmb as are the 3750 switch ports they connect to. Mostly all is fine but sometimes I get duplex mismatches on syslog server. When I change phone settings to 100full it resolves. How come this happens on some and not others.
Also what is best practice as we are deploying in other offices now; I would have though everything set to 100full.
Thanks ,
FrankIf you manually set a port to 100/full then plug in a device set to auto/auto that device will default to 100/half. If you set one device manually you have to set whatever it connects to manually as well. Best practice is to set everything to auto negotiate and that will result in 100/full. In your case you have all devices with a duplex mismatch and you should be having lots of performance and voice quallity issues.
Take a look at this link for details on how ethernet port speed and duplex negotiation works.

XP vs W7 communications coping with duplex mismatch?!?
Whilst deploying a Windows 7 SP1 Pro Standard Operating Environment to one of our 60+ sites we were having some massive comms issues. The site is on a relatively slow (max 2Mbps link), but the difference in consistency between the former XP and
'new' W7 machines is striking
e.g. SOME W7 log in taking 40+mins (compared to XP based machine approx 2mins), RDP sessions from XP based machine fine compared to unusable from W7 machine, Lost SSL sessions on W7 machines compared to 'normal' functionality on XP machines, etc.
So, the fundamental issue appears to have been a duplex mismatch between the router (3rd party managed) and the sites 'core' switch.
However, we are struggling to understand why the W7 machines were so much more susceptible to issues compared to the XP machines... I understand that the TCP/IP stack was fundamentally rewritten between XP and Vista/W7, but can anyone point to anything that
would explain why the W7 machines exposed the issue so much more acutely?
I'd appreciate any thoughts or suggested areas of investigation?
Thanks
DavidHi,
Based on my experience, you may check the netmon traces or monitor the performan which is in the task manager.
Download Microsoft Network Monitor Tool from the following link and install it on the two machines.

Thanks for your suggstionHi Grant,
Thanks for your sugggestions.But however we Have 6 Controllers, all are having the same setup as this one.
Only difference i seen for this switch is for the th port 1/11 it is showling 2 CDP info, one for management interface of WLC and other for Logical interface of WLC, which seems not correct.
Ths CDP info connecting to Logical interface is showing half duplex and cdp info connecting to Physical interface of wlc is showing full duplex.

==================================
I did try to change duplex setting on fa0/0 of router to Full, but the interface went down and I lost the connectivity to the switch.> I did try to change duplex setting on fa0/0 of router to Full, but the interface went down and I lost the connectivity to the switch.
Did you wait some time to let the divices reestablish the connection again?
I would configure the Switchport to auto/auto in that case. Autonegotiation works (most of the times ;-) ). -
Hi,
I have connectivity like this:
customer switch forced to 100Mbps/Full duplex----------My end ME-3400-24TS-D configured for Auto negotiation.
ME-3400 negotiating with 100Mbps/Half duplex.
Customer facing CRC. Forced ME-3400 to 100Mbps/Full duplex, but link is not coming up.
ME-3400 IOS is me340x-metroaccess-mz.122-44.SE.bin
Is it bug related issue?
Regards
SKRAOHi guys,
I´ve been having the same problem whe trying to bring up a link between a gigabitethernet port using the UTP connector and a fastethernet port on a Huawei SW...the only way it works in full duplex /100 is when both sides are auto.
any idea whats the cause of this behavior? -

I have an ASA5510 (7.2(4)) with outside interface conn to ISP's Cisco 2610 (10M Ethernet - NOT FASTETHERNET).
Previously a PIX506E was attached to same router. PIX outside was set 'interface ethernet0 10full' and the router's E0/0 was hard set 'full-duplex'.
This link functioned as desired at 10/FULL.
Now when I conn the ASA I cannot get the link to come up at full-duplex. The 2610 is running c2600-i-mz.123-19 IOS.
Any suggestions from the Cisco community?
PhilI did - that's when the link will not establish.

Forced Full Duplex changes to Half Duplex (no mismatch errors)
Guys,
I am going through a very weird situation and wondered if any of you had any ideas on how I could troubleshoot this issue.
I am running a 2960 Cisco, which has a single mode fiber cable which is connected to multiple rstp switches designed by a mining technology company.
The fiber port which connects these switches has "duplex full" written into its configuration. However, after a random amount of time, anywhere from 1 hour to 24 hours, the port is changes to operate in half duplex. This is found by doing a show interfaces status.
At no time whatsoever is there any duplex mismatch errors.
Once i notice that the port is actually operating in half duplex mode, i log into the port, do a "duplex half" then "duplex full".. the port goes back into full duplex for another 1-24 hour period.
Any ideas on why this port keeps jumping into half duplex operation? I really need this port to run in full duplex and cannot understand why the port would go into half duplex operation when the end devices should support full duplex.
Again, i never get any duplex mismatch errors.
I appreciate any troubleshooting tips you can provide.MSTswitchOVCC#sh version

Speed/Duplex between two different switchs & SFP
Hi everybody,
I'm sorry about my poor english... I'm French (but it is not contagious)
I need your help (or TAC Help ) about speed and duplex problems.
My network :
[C2960G-24TC-L with sfp GLC-FE-100LX on Gig 0/23] <--> (Singlemode Fiber 9/125µ) <--> [Cisco SF200-24 with sfp MFELX1 on Gi1]
Autonegociation everywhere...
My problem :
%CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on GigabitEthernet0/23 (not full duplex), with f02929f97095 gi1 (full duplex).
- I can't force speed/duplex on MFELX1 (actually a-full a-100)
- I can't force speed/duplex on GLC-FE-100LX (actually a-half a-100)
Is there an incompatibility between this equipements ?

Thank you so much for yor help !Thank you Leo,
It doesn't work, but I found an solution !
A strange solution...
I forced the C2960G-24TC-L to work with SFP :
media-type sfp
When I do that, I have the possibility to force the duplex (but not the speed... ok why not... ) :
duplex full
It is not very clean but my link is up and full-100 both sides.
Not very clean because :
C2960 side = force duplex, auto speed
SF200 side = auto duplex, auto speed
No errors... the link is clean.
Anyone known the reason or a better solution ? -
Half duplex or full duplex configuration for MDS9124 management port?
Hi All,
Is it possible to set the management port of mds 9124 about half or full duplex configuration?
I want to correct following error:
Jun 13 10:27:20.799 GMT: %CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on GigabitEthernet4/18 (not half duplex), with mtw1pc02bs0(FOX1450G8QG) mgmt0 (half duplex).
it seems mds 9124 set his port to half duplex.
DennisYou may want to check this thread :
https://supportforums.cisco.com/thread/2059109
Else try the following :
switch# config terminal
switch(config)#
switch(config)# interface mgmt0
switch(config-if)# switchport duplex full
switch(config)# exit
switch#
switch# copy running-config startup-config
Also, I would suggest you check what the counterpart of your MDS switch mgmt interface is set to (i.e. is it set to autoneg, then try setting it to fix speed/duplex or the other way around).
