Half Duplex/100M problem on 2960 switch with GLC-GE-100FX

We have a 2960-24TC switch with GLC-GE-100FX SFP interface converter. We connected the switch to another switch through fiber, one end was GLC-GE-100FX and the other end was a 100/FULL ATI media converter. Both switches could talk to each other. The problem was the GLC-GE-100FX interface running at 100M/half duplex status and we couldn't change the port configuration. Is there a way to fix this problem? Your help would be much appreciated.

Using show interface command. It shows half duplex. It's a new design on Cisco 2960-24TC switches, the Giga uplink ports are dual purposed. When I plugged GLC-GE-100FX SFP interface converter and connected it to a media converter, it showed half duplex. There's no way I could change the speed and duplex under that configuration.

Power up cisco 2960 switch with 12V DC Power

hi all ,
I have some issue with supply power to cisco 2960-24TT-L switch. In my server farm rack is having DC current of -48V. But however cisco switch require 12V DC current.
Cisco Spec.

2960S Switch with a UC520

We have a UC520 but it is esentially maxed out with the 8 port switch as well as an additional 8 port switch. I would like to upgrade to a 24 port switch at a minimum. I was looking at the 2960S-24PD-L for about $1300 at Newegg. How difficult will it be do add this switch to the UC520. I've worked with CLI before, but am by no means great at it.
Thanks!

Hello Reid,
I recommend that you use the SF300-24P or SG300-28P depending on whether you want gigabit or not. (SG or SF). This switch is web gui based. When using with the UC500 there is next to no setup as default settings will be more than fine. I do recommend that you upgrade the switch to the latest Cisco Firmware available from Cisco.com after buying it. You will find the hardware is very reliable and much more affordable for small business than the 2960.
** Please note that the SG300/SF300 switches support 802.3af PoE standard. They will not power old, pre-standard Cisco IP Phones. Check your phone models to ensure they support 802.3af.

2960 switch fiber connection over 40km single strand SM fiber

Hello everyone,
We are having an issue with the connection in the subject. We just gost dark fiber for connecting 2 2960 switches with single strand single mode fiber over more than 10Km.
Looking at the compatibility matrix and the SFP gigabit applications the 1000BASE-BX10 is the best I could find but cannot reach more than 10Km.
Can anyone please propose a solution? If media converters are the only way to go can please sugest manufacturer/model (even with SC connector) since Cisco does not make Media converters.
Thank you
Mario

A 40 km link is usually run using 1550nm wavelength due to lower light loss on the fiber at this wavelength. The 1000BaseEX module is spec'd to 40km and runs at 1310 nm wavelength, but you will lose light through a WDM filter (which is integrated in the single fiber SFP) which would reduce the link's length. I would check with some of the 3rd party media converter manufactures to see if any of them have a lower cost solution that operates over a single fiber at >40km.
Sorry... a link loss budget is the sum of:
Fiber cable loss + fiber connector losses + fiber splice losses + impairment losses (dispersion or PMD) + aging losses (safety margin).
If the transceiver's Loss Budget is greater than the Link Loss Budget, then the link should operate.
www.thefoa.org has some good videos for understanding fiber terminology at an easy to understand level.

1 wire half duplex

Hi, I'm new to this forum and NI/Labview,
Is there a NI cDAQ module that I can purchase for configuring in 1 wire half duplex mode as developed by Maxim. (not RS485 2 wire half duplex)
I could probably achieve this with a tri-state DIO module, but not sure if there is one?
or RS232 module with tri-state capability?

Hi Sparkeyx,
There are a number of NI DAQ devices which support Tri-State DIO. This information can be found in the article below:
http://digital.ni.com/public.nsf/allkb/09B559BE292C75DB8625698500640E0A
Also there is a community example in which the Maxim Integrated 1-wire protocol has been implemented usinf the NI cRIO which you might find useful:

HT203585 a FaceTime half duplex issue with my Mac--OS 10.10.2

I am having a half duplex problem with my Mac---OS 10.10.2
That is, when the party I FaceTime with is talking, they cannot hear me.
I can hear then other party when we both talk---it happens whether or not
I initiate the call or the other party does. It doesn't happen with my iPhone
on the same home wifi network. And it happens on the Mac when
the iPhone FaceTime is turned off too.

Connecting 2 3750 Switches in Stack with 2 2960 switches in full Mesh

Hi Friends,
I have attached a pics which DC design of one of our customer , as network engineer i have design this , so i am responsible for implementing it, now request you all to kindly guide me what would be technical problem i have to face in achieving this and how can i over come .Please be in detail. Waiting for your response .
Regards
Amit Kulshrestha

I have attached modified diagram , please suggest.
The major issue I see is that you have not mentioned whether the 2960's are stacked? For the design to work, they need to be stacked because you cannot create port-channels between them and the Core switches unless then 2960's are stacked.
==> You are right , surely 2960 Switch need to be in stack form.
Personally I would look at more powerful switches than the 2960's, something along the lines of the 3750x range or probably now the 3850's.
==> This is constrain of customer, not our responsibility.
The second issue I see is that your servers are connected to the WAN switches. Is there a reason for this? Usually they would be connected to the core switches.
==> For this If 1 separate 2960 series switch can be used ?.
The final point is that you only have single connections from each of your WAN connections which begs the question as to the purpose of having two WAN switches?
==> Customer is having 1900 series of router , only two ports one used for WAN and other used for LAN.
The objective of having two switches is to provide redundancy/resiliency. If you have only one connection from each WAN then why do you need two switches as there is no redundancy?
==> Customer has agreed to have manual change at the time of failure.

Cisco 2960S FPS-L PoE switch with Avaya 9811g VOIP setup

Hello,
I am connecting a setup for data/voice connecting Catalyst 2960S-FPS-L PoE switch with Avaya 9811g series VOIP phone. As per my knowledge cisco switch works well with Cisco phone as it has got some builtin "Macros" and Intelligent PoE recognition when we connect device getting the details of another device through CDP. I understand I have to create data and voice vlan with QOS then enable trunking on the interface to other switch that is also 2960. Little confuse if is there any compatibility issues with Switch and Avaya phone regarding protocol/data/voice...?
Do I have to do PoE config for each port on the each interface?
any help or detail config will help.
Thanks in advance.

Hi I am back after good research. created two vlan data and voice with trunk on interface1/0/48 given below config..
connection b/w 2960s FPS Switch and Avaya 9611g IP Phone.
lldp/cdp is enable on switch
So I created this config if some one can take a look .
expert advise if something wrong?..
I am only concern with Voice and PoE as voice is my priority. do i have to map something for voice quality?
also if i create another Trunk port one allow voice other allow data both cable will go to switch will that be issue?

Hello!
My name is Robert and I am network engineer for the Cisco SBSC. This is the correct place for the ESW500 series.
From the error messages you are seeing, I would recommend to disable the Bonjour service to see if that helps with the reboots. I am currently looking into the error messages you are getting to see if there is a solution. I would recommend giving us a call as well for immediate assistance on the error messages. Below is a link for our support center numbers.

Duplex mismatch problem

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?

Hi 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?

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.

IDS-4210 picks up what IPS-4240 misses, strange duplex/interface problems

I just installed a IPS-4240 inline on our primary internet inbound connection. I decided to leave the 4210 in place for a week or two while I tuned the signatures. It is receiving a span of the same traffic that the 4240 is receiving.
I noticed today that the 4210 is picking up sig 3250 and the 4240 is no. The first thing I checked to make sure that the 4240 has this signature enabled, and it is. Anyone have any thoughts? BTW, All sensors are on the same version 5.1.1 and running s211 and managed through VMS.
I would also like to mention that I had issues on the 4240 and its interfaces. Management only runs at half duplex and the interfaces that connect to our PIX. I ended up having to put a switch between the 4240 and the Pix 515e to solve the duplex issues.
Anyone have any thoughts on this part

I had the same duplex problem with my 4240 sensor connecting to my PIX. The only way I could get it to work without errors is to set both the sensor and the PIX interfaces to auto/auto. I worked with Cisco on this problem. No resolution, just the workaround. As far as sig 3250, IPS and IDS signatures may be a little different. I assume you span from the inside and run your in-line outside your firewall? If this is the case, then the 4240 sensor may see different traffic than the 4210.

FaceTime audio half duplex / doesn't work simultaneously

I gave my parents a new iPad Air for Christmas. Note: They are 'older' and have a lot of trouble operating electronic devices. Before sending it to them I did check for recent updates, set up their email and contacts, installed some apps that I find useful and uploaded some photos. Otherwise it's a fresh unit right out of the box.
Yesterday we tried facetime with them. The video worked as it should. The audio seemed to be in a 'half duplex' mode on our device. Meaning, they could hear us perfectly and normally on the iPad. We could only hear them when we were perfectly quiet. Any sounds or talking on our end would mute their transmission during and about 1 second after speaking.
We tried multiple calls. (I called them and then they called me). We tried an iphone 5 and a MacBook, the problem was consistant in all cases. During one of our calls on the mac, my brother placed a facetime call to my phone and his connection worked perfectly, while my parent's connection continued to have the issue.
I sent them the following instructions, in hopes that it may fix the issue, but I'm doubtful. I don't have an iPad handy (only iphones and the mac in our house) so there may be some settings that are present on the iPad and not on the iphone that they should try. Any and all help would be appreciated! They live on Kauai, HI so if there are any places there that would be helpful that they could visit, I would appreciate the recommendation.
Go into settings, scroll down until you see facetime. Select it. There will be some settings for facetime. One simply says facetime and there is a small green slider button next to it. Touch the button. It should slide and turn white. This disables facetime.
Go to settings, then general, then software update. It should say "checking updates" and then will either display your version (7.0.4 ?) OR it will say there is a new update and you can download it. If so, download/install. (Should be a button asking and just hit yes or ok).
Next, do a network reset:
Go to settings, general, scroll down to "reset". Select reset and then select "reset network settings". It will ask if you want to do this and yes, you want to do it.
Next, After all this is done, reboot the ipad. This is done by pressing and holding the top (power/sleep) button and the home button down at the same time. Hold it for 30-seconds maybe longer until the screen goes black and then the apple logo appears. Then let go.
(If you hold just the upper button for 5 seconds a red slider will appear to allow you to turn off the ipad. For a reset just ignore that and keep holding down the buttons).
Once it reboots, add yourself back to your network. It may ask on its own, but if not :
Go to settings, then wi-fi. Select your network and enter your password.
Last, go into settings, general, facetime and turn it back on by touching the white slider button. It should turn green.
I found two other cases that sounded like mine:
https://discussions.apple.com/message/22808569#22808569
https://discussions.apple.com/message/22705969?searchText=Facetime%20duplex#2270 5969

My parents called apple tech support. I'm not exactly sure what they did, but I think they just rebooted the iPad again, as done previously. It seems to be working better now, although it does still cut out now and then from sounds on my end of the line.
Another thing that seems to have helped, I determined that my parents had left it in the original plastic packaging and then crammed it into the case I gave them, which may have slightly muffled their microphones.
Anyway between these two things it is working better. We can speak on this end and still hear them talking. But now and then it still cuts out.
