Poweredge (Win 2003) port teaming problem with Cat 6509s

Hi
One of our server guys has reported a problem with port teaming his Win 2003 Dell servers (running MS Exchange). He has set them up with an active port attached to 6509-A and a standby port attached to 6509-B. The servers have Broadcom NICs. At times the server is completely unavailable - unable to RDP or telnet and users have complained of poor performance.
Does anyone hae any experience - any info gratefully received.
Regards,
Paul

I'm not so sure CSCsj55739 is the issue. I have a few questions:
1) Can you post a text dump of the Broadcom team config (usually available from the teaming GUI).
2) Are both NICs connected to the same VLAN?
3) Is this same VLAN carried between 6509-A and 6509-B?
4) Have you tried removing the team and putting the team address on one physical NIC at a time, to see if simply one NIC or the other has a connection issue?

Port Mapping Problem with AEX

I have a new Airport Extreme and a problem that did not exist with the Airport. I connect a Toshiba network camera to an Airport Express, set as a WDS remote, with the netcam connected to the wired ethernet port of the Express. I can see the netcam, which also functions as a web server, on the internal 10.x.x.x address, and have reserved a discrete 10.x.x.x address via the MAC/DHCP reservation function of the Extreme. Just like the older Airport which did this without a hiccup, I should be able to map a port (e.g. 1200) on the public IP to port 80 of the internal 10.x.x.x address, then access the netcam on the internal network from any browser (http://67.x.x.x:1200). My cable modem is just that: no router involved other than the Airport Extreme. I'm using the latest Extreme and Express firmware, and am either missing something with the new Leopard firewall, overlooking something else, or dealing with a product flaw. Any help is appreciated and Happy Holidays.

I have forwarded the port (have tried several different ports actually) in what I think it the correct way: using the Airport Utility, connected to the Airport Extreme, and, under advanced options, selected port mapping, entered the public TCP port of 1200, then the private 10.x.x.x IP address of the netcam (which I can access from the internal network with no problem), coupled with the private TCP port of 80. I then attempt to access the netcam from the Internet by entering http://my cable modem IP address:1200 (or another port to which I've attempted to map). This method worked for two years with the Airport, but, with the Extreme and Leopard (simultaneous transition), I'm stumped. After reading other about other port mapping problems, I reserved an IP address for the netcam based on its MAC with no positive results. I also set the firewall through the Security icon in System Preferences to allow all incoming connections. Thanks for taking the time to respond.

ThinkPad USB 3.0 dock network port has problems with our Cisco 6509 switch

We purchased a ThinkPad USB 3.0 dock for and X1 carbon and the main issue we are having is the network port does not seem to work with our Cisco 6509 switch. I tried updating the firmware on the dock but it still hasn't fixed the issue. I was wondering if anyone else had run into this problem with any other networks out there.

I'm seeing the same issue with a ThinkPad W520. When I connect my ethernet cable directly to the laptop, my internet speeds are on par with my service provider of 18 Mbps. When I move that cable to the dock, I will only see 1.5 Mbps. I have two displays attached to the dock and I'm running Windows 7. I've updated the dock firmware and have installed the latest system drivers. Is there anything else to try?

802.1x RADIUS authentication problem with Cat 2950 to CiscoSecure ACS 3.3

I wondered if anyone can help or shed any light on the following problem.
I am getting an authentication error when doing a RADIUS authentication to CiscoSecure ACS 3.3 running on a Windows 2003 server, the authentication request is coming from a Catalyst 2950 switch which is doing 802.1x for Windows XP clients. This problem only happens when the XP client connects to 2950 switches, Cat 3550s and 3560s work fine.
The Cat2950 is running 12.1.20 (EA1) which is more or less the latest IOS.
The error I get from ACS 3.3 is "Invalid message authenticator in EAP request" when the 2950 tries to authenticate an XP client for 802.1x to the ACS server using RADIUS.
Doing a RADIUS and 802.1x debug on the 2950 I see a message about 'Unknown EAP type', I am using PEAP on the XP client doing EAP-MS-CHAPv2 authentication, the same XP client authenticates fine with 3550 and 3560 switches problem only affects 2950s. Can anyone confirm the 2950 supports EAP-MS-CHAPv2?
I have checked and re-checked the shared secret and it definitely matches on 2950 and ACS.
One thing I noticed in the RADIUS debug is the 2950 sends 18 bytes for attribute 79 when the RFC defines attribute 79 should be 3 bytes or less, I don't know if this is related to the problem or is correct behaviour.

Hi, I am new with 802.1x, and was hoping that someone would help with these queries:
1. How is a certificate requested without being allowed on a network that is not authenticated with 802.1x. I had to first connect to an active network, retrieve a certificate with the proper username and password, and then physically connect to the port on the 2950 switch which was enabled to do 802.1x
2. My config is as below:
aaa new-model
aaa authentication dot1x default group radius
aaa authenication login default group radius
dot1x system-auth-control
interface f0/1
switchport mode access
dot1x port-control auto
end
I able to login using the radius server, so radius is working (on ports other than f1/0). However when connecting to f1/0, the port on the 2950 remains blocked.
3. The certificate is issued by the ca server, is viewable via Internet explorer,and is issued to the correct username which is on the active directory.
I even tried using local authenication with 802.1x, this did not work
4. If I have a certificate, will this automatically give me access to the 802.1x port?
5. I have windows 2000, and authenication is set to 'Smart Card or other certificate.
Am I missing anything?
Any advise will be greatly appreciated

Yoga 2 10inch with Win 8.1 and problem with CCleaner

Hi guys!
I bought my new Yoga 2 10inch with Win 8.1 few days ago and everything was all right, until i installed CCleaner. The CCleaner app window doesn't move smoothly when i'm using it by touch screen and touch pad, choosing the options works slowly and it doesn't display correcly...
Do you have the same problems?
Thanks a lot and sorry for my english

I guy on Youtube made a rough tutorial.
http://www.youtube.com/watch?v=lI8AnNBIlLQ
Englisch subtitles available
In the comments he suggests, to download the Iso with anouther win-8.1-key - no matter which one - and to install the system clean. In his opinion the system will get the key from the hardware. He is writing, that there is just a universal iso. So it's no problem to download an iso with another key, even if your system is a Home-Edition and you download it with a Pro-Key.
I will try this.

TimeCapsule Problem with CAT 6

Hello,
I have wired my house with quality CAT 6 cables. My iMac, and TimeCapsule have been working fine for two months. Then last month the iMac quick communicating with the TimeCapsule via ethernet. Multiple cables were tested on my fluke and other cables were tried, but still the iMac is intermitent and can't see the TC. The exact cables work and my PCs can see the TimeCapsule right away, but now the iMac can't. Well the iMac can if I let it sit there for about 24-48 hours, but when I reboot the TC I lose it again. If I put another Cat 5e cable anywhere in the length back to the TC it starts working. I am very confused as this has worked for a couple of months now. I have a gigabit connection and even though I can replace that one cable with a CAT 5e I still want to know what is going on. The link light on the TC is green for two seconds then off for two seconds, then green for two seconds, etc....
Thanks for any help you guys can offer and I will answer any questoins if you have them.

Thank you Gary.
The problem is also that do you have a movie in slide, the movie was truncated and not reproduce all it.
This feature is very important in a world where the video contents are the prime expression of comunication.
Six months are one life...
i've rewinds the old version

Port-channel problem with WiSM

Has anybody met following similar problem:
I put WiSM into slot 3(also tried slot 6) of 6506(sup720-3B, s72033-adventerprisek9_wan-mz.122-33.SXH.bin), using following command to setup the port-channel:
interface Port-channel1
switchport
switchport trunk encapsulation dot1q
switchport trunk native vlan 5
switchport trunk allowed vlan 1-1000
switchport mode trunk
int range g3/1-4
switchport
switchport trunk encapsulation dot1q
switchport trunk native vlan 5
switchport trunk allowed vlan 1-1000
switchport mode trunk
channel-group 1 mode on
I can use "session slot 3 pro 1" to login to the WiSM, but can't ping WiSM's management IP address from 6506, then I find the port-channel has problem, only G3/1 is up and included in the channel, G3/2-4 are up but line protocol is down, then I found from the log that: "AESUT: %EC-SP-5-CANNOT_BUNDLE2: Gi3/2 is not compatible with Gi3/1 and will be suspended (qos-card type unavailable for Gi3/2 or Gi3/1)". It says those GE port are not compatible for qos-card type, but I checked the configuration, all GE using the same configuration. Don't know why, maybe a bug? Appreciate for any feedback

I have the same problem, but it has something to do with QoS. When you disable "mls qos" on the switch, the port-channel will function normal again.
It doesn't help when you configure "mls qos trust dscp" on the port-channel!!!!!

Port forwarding problems with WRT610N v2 + WAG54GS v1.0

Background:
I have a WAG54GS v1.0 (Annex A) which I was using to handle my home network and my ADSL connection. I bought a WRT610N v2 (which I'll refer to as the router) with the intention that it would replace the networking duties of the WAG54GS (which I'll call the modem), which would be relegated to just handling the Internet connection. Both are running their latest firmware.
I've gotten this configuration to work, but with one problem: I've lost a lot of flexibility in regard to port forwarding. The problem is that the only way I've managed to get the Internet to work is by having the router on 192.168.0.1, and the modem on 192.168.1.1. If I try and have both on 192.168.0.x or 192.168.1.x then connecting to the Internet no longer works under any configuration of options I've tried.
What this means is that when I go to setup port forwarding in the modem, I can only forwards to clients on 192.168.1.x, but the router can only forward to 192.168.0.x. The only things I can get to work are situations where port range triggering can be applied, so only when a connection is made on the relevant port to an external IP, and then that external IP also communicates back on that port. As you may guess this doesn't nearly cover all cases.
Question:
Should it be be possible to have both router and modem on either 192.168.0.x or 192.168.1.x, which would allow port forwarding to work as expected. That should have in theory been possible with the modem's bridge mode except that it's then impossible to configure the PPPoA settings necessary to connect to my ISP.
Or am I going to have to rethink the network layout (i.e. buy a dedicated ADSL modem and fully retire my WAG54GS?)
Solved!
Go to Solution.

Actually in the end what I figured out was that as far as my WRT610N was concerned my WAG54GS was my ISP, and that was all it needed to know about the Internet connection. So I set it to connect to the WAG54GS with a static IP, stuck that IP into the WAG54GS's DMZ, and left the WRT610N to handle port forwarding as all devices that connect will do so through that. (Yes, I've disabled the wireless features of the WAG54GS)
I'm reasonably sure I tried the combination of settings you've suggested (including moving the WAG54GS off the Internet port of the WRT610N, which I would have wanted to avoid anyway as I have four permanently connected devices anyway) and found it still wouldn't work. And I wasn't trying to set both to 192.168.1.1 at any point, my self-obscured point was that changing only the last block of the IP address failed to work for accessing the Internet.

Outlook 2003 & NOKIA 6630 problem with some fields...

Dear All,
I'm having a wierd problem, I do the PC SYNC between my NOKIA 6630 and the outlook 2003, everything is working fine except for some numbers under certain names.
I realized that the number that do not go from the phone to the outlook are the ones with a field in the mobile, where this field s not available on the outlook,
For Example:
First Name:John
Last Name:fdfdf
Mobile:01010101010
Mobile (home):93848484
Tel(home) :49834574
The outlook will take all info except the Mobile(home) firled as it is not available in the outlook.
Does anybody know how to fix this problem?

The only way is not to use double mobile numbers in phone because Outlook has the limitation that it thinks that a person can only have one mobile number.
It is about trial and error, use the default fields in Outlook and check that those sync to phone and then use only those fields inphone if you add a contact to phone.

Port Mapping problem with a Snow Base Station

I wish to enable port mapping with my Airport Snow Base Station. (SBS) I am using an Earthlink Efficient Stream 5667 DSL modem to my SBS. I am running firmware version 4.0.9 and connecting with 10.4.3.
So -- enabling port mapping requires that the IP address on my 10.4.3 computer doesn't change, and that I then map the ports. However, I can not manually assign an IP (say 10.0.1.201) as my 10.4.3 can not connect using either "DHCP with manual address" or "manually" (where the router and subnet mask match the DHCP assignment)
What should I do?

Do not use the "DHCP with manual IP address" - that is a mode not supported by most networking devices on the market.
What you should do: on your Mac, open System Preferences->Network->Show Airport->TCP/IP tab. Select to "configure manually". Then enter the following parameters:
- IP address: 10.0.1.201
- subnet mask: 255.255.255.0
- router/gateway IP: 10.0.1.1
- DNS IP: use either 10.0.1.1, or enter the actual IP address(es) of your ISP's domain name servers

Thunderbolt port color problems with panasonic plasma tv

I have a MBP 17" latest model. When I connect my Panasonic 50" Plasma via Thunderbolt to HDMI adaptor through a Western Digital 6TB Thunderbolt hard drive, the colour is very pink/purple. If I plug the HDMI adaptor to the Panasonic direct to the MBP Thunderbolt port, bypassing the hard drive port, the color is fine. Any solutions guys?

Did you find a solution to this issue? I have the same issue now after years of no problem using the mini display port to DVI through a drive.

Port reusing problem with sockets.

I have the following simple client/server classes. I can't get the client to reuse ports. When creating 5 sockets (not simultaneous) to the same endpoint 5 new local ports are opened and when closed set to TIME_WAIT.
The code:
Client:
import java.io.IOException;
import java.net.InetSocketAddress;
import java.net.Socket;
public class SocketClient {
   public static void main(String[] args) {
      new SocketClient();
   public SocketClient() {
      for (int i = 0; i < 5; i++) {
         Socket socket = new Socket();
         try {
            socket.connect(new InetSocketAddress("tonic", SocketConstants.port));
            socket.setReuseAddress(true);
            socket.getOutputStream().write(3);
            try {
               Thread.sleep(100);
            } catch (Exception ex) {}
            System.out.println("socket.getInputStream().read() = " + socket.getInputStream().read());
         } catch (IOException ex) {
            ex.printStackTrace();
         } finally {
            try {
               socket.close();
            } catch (IOException ex1) {
               //.. do nothing
}Server:
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
public class SocketServer {
   public static void main(String[] args) {
      new SocketServer();
   public SocketServer() {
      ServerSocket servSocket = null;
      try {
         servSocket = new ServerSocket(SocketConstants.port);
         servSocket.setReuseAddress(true);
      } catch (IOException ex) {
         ex.printStackTrace();
      while (true) {
         Socket socket = null;
         try {
            socket = servSocket.accept();
            System.out.println("socket.getRemoteSocketAddress() = " + socket.getRemoteSocketAddress());
            System.out.println("socket.getInputStream().read() = " + socket.getInputStream().read());
            socket.getOutputStream().write(4);
            System.out.println("socket.getInputStream().read() = " + socket.getInputStream().read());
            try {
               Thread.sleep(400);
            } catch (Exception ex) {
               ex.printStackTrace();
         } catch (Exception ex) {
            ex.printStackTrace();
         } finally {
            if (socket != null) {
               try {
                  socket.close();
               } catch (IOException ex) {
                  ex.printStackTrace();
}Do I need to use socket.bind(..) or how can I get my client to reuse ports in TIME_WAIT state?

The TIME_WAIT state is there for a reason; it's your friend and it's there to help you :-)
- The Socket FAQ: http://www.developerweb.net/forum/showthread.php?t=2941
Why do you think TIME_WAIT is a problem? Try not to shoot yourself in the foot; don't use setReuseAddress(true). Read the FAQ entry.

1130AG Access Point PoE Problem with Cat 3750G-24PS-E switch

I am having a problem on the PoE negotiation of Catalyst 3750G-24PS-E and 1130AG Access point. I used straight and cross cable for physical connection since by default the auto mdix per port of the switch is enabled/on. I used CLI, CNA and Web Device Manager on both devices to isolate and troubleshoot the problem but still the PoE negotiation on both devices won't work out. But when I used the access point into other switch (CE500 PoE Switch), the access point is working properly. Does anyone can help me to distinguish what the problem really is? The IOS Version of 3750G switch is 12.2(25) SEE2 and the 1130AG access point IOS Version is 12.3(8)JEA.

Hi Rob,
Thanks for your reply. Yes, I tried shut/no shut on the switchport many times. I saw that the switch grant power inline on the port but the port still can't/won't provide any power to boot up the access point.
Thanks,
Nelmar

Problem with CATS

When the CATS profile is configured from Monday Sunday ( Monday being the first day of the week)
The Week period shows up in the header.Eg. it shows 13.2007 which signifies the 13th week.
Problem:
When the CATS profile is configured from SUNDAY SATURDAY ( SUNDAY being the first day of the week)
The Week period Field disappears. How to activate that?

Hi Ram,
I am using Period type as 2, Period as 1 and First day of the week as 1 i.e Sunday cause I need to enable it appear in the time sheet.
My problem is when I enter the First Day of the Week field as blank; the system shows the Week field on the top right hand side in CAT2 (Time Sheet).
But when I change the First Day of the Week field to any other initial it doesn't show the Week field in the Time Sheet.
Please gimme your phone no. so that I may call you if you still want me to explain it to you.
thanks,
Puneet
