WAN Port Full Duplex

I have connected my UC540 latest software pack to a FIOS Box. i'm only getting half the speed.
Can someone post the steps on CLI to make the WAN interface full duplex please?

It would be `interface FastEthernet0/0` for a UC540 actually.
In any case, I believe they are set to "auto" by default... which should have chosen full duplex.
From his description it sounds more likely that he has a throughput problem than a half-duplex issue.
How fast is your FIOS connection? The UC500's aren't really designed for very high speed WANs.
The other thing to check would be traffic shaping settings, if misconfiged, they could certainly limit your speed.

Can I build a full-duplex serial port?

I want to build a full-duplex serial port with PCI-6533, main features are:
software: LabView
hardware: PCI-6533
serial port: full-duplex,synchronized
clock: 13MHz, external feed
control lines: 3
data: about 1k bytes to be transfered
Thanks and best regards,

You can build it, but it won't be easy. Transmitting should be OK. But, for receiving, you are going to have to parse the information out of your incoming bitstream to get the information from the frame.
Also, there is a peculiarity when usng the 2 timing sections together on the 6533. If you use any data width greater than 8 bits, you are only going to get 10MHz on each 'side', since the data has to be split between them by word. However, since you are serial and only using one bit, you don't have to worry.

How do I set up the port interface for the WAN side of my RVS4000 to 100T Full Duplex?

How do I set up the port interface for the WAN side of my RVS4000? The ISP says I need to set it to 100T Full Duplex, but where would I do that? In the Router's administration GUI I can't find any options to make such settings for the WAN side.

The setup of the folders in Finder is entirely up to you. Whatever suits your needs is what you should do. Lightroom will be fine no matter how you set it up.
So I'm not really sure what your question is.

How to setup a WAN port to 100Mb Full Duplex

Planning in getting a 100M WAN circuit. The requirements are to set the TC to 100M Full Duplex mode (No Auto Negotiation), able to set Static IP's. Can this be possible?

Yes, when you setup the TC as a router.. on the internet tab doing manual setup it will allow you to fix the wan connection speed. You can then use the TCP/IP page in the same area to set a static IP.
BTW a cheap $10 switch 10/100 would fix it even if the TC did not have the controls.

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.
Dennis

You 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).

EA6500 manually select speed and duplex for WAN port

Is there any way (hidden settings?) to manually select speed or duplex for WAN port on EA6500? I'm using EA6500 with Genexis HRG1044 (FTTH) and the latter has known issues with upload speed when local device is connected on gigabit. It seems that both EA6500 and Genexis HRG1044 only support autonegotiation and that always results in gigabit which results in poor upload speeds over the internet. Placing 100 Mbps switch between EA6500 and Genexis HRG1044 does the trick but I was wondering if it can be done without it. BTW, my internet speed is only 100/100 Mbps anyways.
Solved!
Go to Solution.

@discoHR If you don't mind me asking, for what purpose do you want to adjust the speed on the WAN port of the EA6500? Is it to increase the upload speed? I'm just spitballing, but I don't think there's any "hidden setting" to adjust it on the EA6500.

WRVS4400N Hard Set WAN port speed and duplex???

Does anyone know if there is a way to hard set the wan port speed and duplex on a WRVS4400N V2 router?
Any Help greatly appreciated..
thanks,

Michael
I believe that these statements are true.
Auto negotiation is good when both sides are configured to negotiate. When one side does not negotiate the other side should not try to negotiate.

WAN port configuration SA520w

We switched to another internet provider and have problem with our SA520w and a slow WAN connection on av fibre connection.
We have confirmed that we need to set/ force the WAN port interface on the router to use 10base-t (Full duplex) in order to get maxium speed from our Internet provider. Is there any solution force the router to use that settings as I cant find that alternative on the port setting page in router configuration?
Latest firmware installed
Thanks

Hi,
You can change speed and duplex settings at Networking->Port Management -> Port Management.
Thanks,

Wan port question

Could someone explain to me the Ethernet wan port menu. I'm having a lot of connection problems with Airplay. It keeps dropping and coming back on.
I checked with my ISP and the signal (cable) is 100% stable so the problem has to be my AE.
If I change the settings to 10Mbps/half Duplex, it seems to work ok for a while. But Automatic is a definite no-no.
Why all those choices, especially half and full duplex and what do they mean in terms of overall performance ?
Thx

My question to you is did this always happen or just started happening with this modem & AirPort base station. What is the exact model of your AirPort? How about the modem?
This has always happened since installation 3 months ago
AE 1143 - Modem is : Motorola SB5101
Is 8 Mbps the maximum rated download speed that your ISP is providing you for Internet service?
Yes
Is 8 Mbps the maximum rated download speed that your ISP is providing you for Internet service?
Speed test (http://www.speedtest.net/)
up: 8.17 - down: 1.02
Changing the WAN Ethernet port speed will do nothing to improve AirPlay's performance.
But it does ! With lower speed = less drop in feed. Or maybe it's just the fact that I change from one to another.

Nothing is connected to the ethernet WAN port

I have a 5th generation AEBS and FTTH. When I plug it into the wall, it reports that nothing is connected to the ethernet WAN port, but if I plug my MBP into the wall I get an IP address and can hit the Internet just fine.
I called tech support and they said that everything looks great from their end, and that there is nothing that they can do.
What I have found is that if I plug the cable from the wall into a gigabit switch, and then plug the AEBS into the switch, everything works fine!
Any idea what can be going on? TIA!

This is increasingly a problem.. the AEBS is not actually negoiating the speed correctly with the ONT supplied by the ISP.. it happens a lot with cable modems as well.
Using the switch allows the two devices to negoiate speed correctly.
You can do the same thing with old utility..
Install 5.6 utility on your computer. Here is a method.. there are others.
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
Leave the package open on the desktop so you can see the file. AirportUtility56.pkg
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. If your Mac refuses to run the software, because it wasn’t downloaded from the Apple store, go to security in preferences and allow other software to work.. this is limitation of trade methinks. You can set back later if you like.
Now drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. in finder, open the new directory, drill down.. applications, utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall version 6 (now 6.3 if you updated) so don't try.. and you cannot or should not run them both at the same time.. although I have had no problems when doing so.
Now with a real utility instead of the toyland edition you can do something about the WAN speed.
Set to either 100mbit full duplex .. that would be my first option.. and second is 100mbit half duplex.
Another alternative just popped up.. buy a crossover ethernet cable.
https://discussions.apple.com/message/23236139?ac_cid=tw123456#23236139
These cables are no longer required with modern equipment but you will find stores still stock them. For some strange reason.. in the one case reported that worked.. this indicates that the TC has some fundamental port issues.. and the mdix is not working correctly which is why the switch or manually setting port speed does.

Airport Utility: Ethernet WAN Port setting

In Airport Utility > Internet > Internet Connection .. is a property called "Ethernet WAN Port". The default setting is "Automatic (Default)".
When I set this property to "1000 Mbps/Full Duplex" Airport Utility throws two interesting errors:
1) You have nothing plugged into your WAN port (But I do have my Comcast modem plugged in there)
2) You don't have internet.
Upon Visual inspection of the Comcast modem, my IP connection to the house is gone. Specifically the green "PC" light is off.
Now, when I change this property back to "Automatic (Default)" my IP connection comes back again.
Does anyone have any thoughts or advice on why this is? I should also mention one more interesting thing ...
When downloading a 40min (1 hour TV show) from iTunes it takes 15 minutes when my Mac is direct connected to the Comcast modem and 3 hours when my Mac is connected to the AEBS. I'm trying to change the "Ethernet WAN" property to 1000 Mbps/Full Duplex to ensure smooth connection from Mac to AEBS to Comcast Modme to Internet.
Thanks!

Bob, thanks. Makes sense.
Do you have a notion of why the Comcast speed is cut when AEBS is connected to it vs. when the MacBookPro is directly connected to it?
Example: Download 1.1GB file from iTunes (Episode 1 of Lost) - a 40 minute TV show
Test 1: MacBookPro > WiFi (802.11n) > AEBS > Comcast Modem = 3 Hours (longer than show!)
Test 2: MacBookPro > Ethernet > AEBS > Comcast Modem = 3 Hours
Test 3: MacBookPro > Ethernet > Gigabit Switch > AEBS > Comcast Modem = 3 Hours
Test 4: MacBookPro > Ethernet > Comcast Modem = 15 MINUTES
Thanks,
Brian

Setting WAN Port Speed on RV180

We have an RV180 and can not get connected to a port on CPE equipment after setting the WAN port on the RV180 to 100/Full.
The CPE equip port is set to 100 Mb/Full Duplex. When the port on the RV180 WAN is set to AUTO and we connect to the CPE we see a lot of CRC errors and very poor performance. When we set the RV180 WAN Port to 100/Full we see no traffic at all.
We have a Cisco ASA 5150 router connecting to the a different port on the same CPE and when we set its port to 100/Full we see very good performance.
We have upgraded the RV180 to the latest FW (1.0.3.10) but that didn't solve the problem.
Can anyone provide assistance with setting the WAN port to 100/Full with success?
Thank you,
John

Hi John, incrementing CRC errors traditionally indicate a physical problem. I've not known it to indicate anything different.

Speed limitation on Time Capsule Ethernet WAN port

I have a Time Capsule 2TB model A1409 that is connected to a Motorola Cable Modem SBV5121 and only connects to it ("green light") when the Ethernet WAN port is set to 10 Mbps/Half Duplex (fastest speed - average 5 Mbps for download) or 10 Mbps/Full Duplex (slowest speed - average 3 Mbps for download). No other mode can get a connection "green light". Time capsule software is 7.6.1.
Today I connected a Cisco Linksys E2500 router to the same cable modem and download speed increased to 10 Mbps which is what I am paying for my ISP. I haven't even touched the ethernet WAN port configuration. Straight forward.
I would be grateful if someone could point out a configuration change that would allow my TC to connect as fast as this Cisco router.

It works fine in Bridge Mode with a Thomson Integrated Modem/Router. But I don't want to use this configuration since I won't be able to use the TC's Guest Network.
Just tried connecting with Cisco's ethernet cable but remained the same.
Is it possible to bridge the Thomson??
Stick a small cheapo switch between the TC and Morotola and see if that fixes it.. as I said, not all chips quite talk to each other.. even in this day and age.
And Motorola cable modems seem to have more problems than most .. this is not new to me.

WAN port limited to 10mbps on PPPoE

Hello,
I'm having trouble with the WAN port on my Airport Extreme. I got FTTC (fibre) coming into a VDSL2+ modem. When I connect my Mac directly to that I get roughly 70mbps download speed. But when using the Airport Extreme my connection caps at 10mbps! I have the 3rd generation, so all ports should be gigabit ethernet ports.
I saw some other posts here suggesting to set the WAN port settings in Airport Utility. I can't find those in the latest utility, so downloaded Airport Utility 5.6, changed from PPPoE to Ethernet, set the WAN speed to 1000 duplex and set it back to PPPoE. Now it refused to connect at all and claimed the cable was unplugged. Not until I went in and set Ethernet to "automatic" did it connect again via PPPoE. So it seems that my Airport Extreme refuses to use a faster ethernet connection than 10mbps when using PPPoE.
Any solution to this? There clearly is something wrong here! I contacted my ISP and they said that they have reports from other users of the Airport Extreme with the same problem.

You didn't mention this, but it could be as simple your cable from the modem to the router. If you are using a Cat5 Ethernet cable, you need to be using a Cat5e or Cat6 cable. I use Cat6 cables on my network because they are certified to run at Gigabit speeds. Cat5e is not certified but can work on a Gigabit network.
Also, when you direct connect your Mac to the AEBS you should be getting download speeds well over 100 Mbps, depending upon your system provider and what speed you're paying for. This leads me to believe it's the cable.

Can not config full duplex on Gi0/1 of WS-C2960-24TC-L

Hi,
I have a problem when connect two modules GLC-FX-100FE to two switch WS-C2960-24TC-L as below:
When I plug each SFP module like above to each switch WS-C2960-24TC-L to SFP slot (gigabit 0/1: dual purpose port), then the duplex become to Haft.
So, I can not configure them to full duplex as other copper ports.
But when I use two switch WS-C3560G-24TS-S, I can do this.
OS version of WS-C2960-24TC-L I am using is: c2960-lanbasek9-mz.122-55.SE7.bin, I think it is new.
Please help me solve this problem.
I have to explain to our customer in the next morning. You know, I am Vietnamese and in Vietnam, the time is 22:40 pm,
Thank you so much.

Hi,
in interface configuration mode you have to configure
media-type sfp
Afterwards you can configure media-specific parameters like the duplex mode.
Note: Changing the media-type will cause an outage for a couple of seconds.
Hope that helps
Rolf
