Content Switch sending request to both servers

Hi,
I have following configuration on the content switch and it send the request to both the servers. due to two tcp stream from going via two different server it second request fails and generate false alerts.
It was working fine but since last week it is giving lot of false alerts.
content StatePMVQLMVMS_8PR3
    vip address X.X.X.X
    add service W8PRAKLQLM01_StateVMS_8HTTP3
    add service W8PRAKLQLM02_StateVMS_8HTTP3
    advanced-balance sticky-srcip
    port XXXX
    protocol tcp
    active
Please let me know what should I check to get this fixed. I hardly work with content switch.
Is there a way I can set up to send all the request to primary server and when it dies then and only then it send a request to secondary and when primary comes back online it restore back to primary ????
I am fine if it does not load balance .. but at least it stop sending false alerts..
Thanks.

Hi Nilay,
You have configured sticky based on src-ip which means that as long as src IP remains same  the user would be sent to the same server.
Now a situation where CSS starts sending the request to different servers could be due to the fact that sticky table was full. In that situation a new connection from same user will be load balanced according to the LB method.  If the sticky table is full and none of the sticky entries has expired, the CSS rejects the new sticky request.
You can use sticky-inact-timeout to ensure that sticky entries flush out after they have been inactive for some amount of time.
Please visit the below link for more details about it.

  • Firefox apparently sends requests that some servers cannot understand. For example, if I try to log out of Facebook, I get an error that says it is a bad request. Same thing doesn't happen with Safari.

    I get this message:
    Bad Request
    Your browser sent a request that this server could not understand.

    Not sure from your example but it appears that the address doesn't have a full domain, i.e., the part between http:// and the next / is not a valid internet domain name, e.g.,
    http://sometext-webproxy/
    In that case, it's probably something running on your computer, either as part of your security software, or as a Firefox add-on, or malware.
    A standard diagnostic to bypass interference by extensions (and some custom settings) is to try Firefox's Safe Mode.
    First, I recommend backing up your Firefox settings in case something goes wrong. See [[Backing up your information]]. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
    Next, restart Firefox in Firefox's Safe Mode ([[Safe Mode]]) using
    Help > Restart with Add-ons Disabled
    In the dialog, click "Start in Safe Mode."
    If you can access sites normally, this points to one of your extensions or custom settings as the problem.
    To also disable plugins, you can try here:
    orange Firefox button ''or'' classic Tools menu > Add-ons > Plugins category
    Any change?

  • DNS request behind content switch: troubleshooting

    Hi, sometimes we experience problems resolving a dns name behind a content switch. The problem solves himself after 5 minutes or something like that. We see the dns request on the dns servers subnet. It looks like the is a problem when the packet returns. I'm thinking of a nat problem. How can i best troubleshoot this?

    Can i e-mail you the config file? I will also e-mail as soon as possible a network capture in front of the CSS. Where can i e-mail it? For the moment dns is working so i will have to wait for network capture untill it fails again.

  • How to send request to web service using .pem certificate.

    Dear All,
    I have a .pem, WSDL file and (Request and Response format), this files are provided by the customer, now I have generated the ServiceClass using WSDL file using wsdl.exe.
    Now when I send the request I am getting error as "The underlying connection was closed: An unexpected error
    occurred on a send" when I told my customer to remove the certificate validation from their web service the "Request
    and Response both are working fine".
    When I opened the .pem file in notepad the content was 
    -----BEGIN CERTIFICATE-----
    dfkhdfhsdfghgfjhAklajdaJHZKkjjHAKJhjkhkjhkjhkjhkjJKJHKJ......................................
    /R-----END CERTIFICATE-----
    and nothing else was there as per my client my code is proper for sending request to web service but the using of file i.e .pem file is not proper.
    I want to know what else I have to do my customer have given me only .pem file with -----BEGIN CERTIFICATE-----  and -----END CERTIFICATE----- nothing else in the file.
    Can anybody please help me in this, below is my code snapshot.
    try
    var pem = System.IO.File.ReadAllText(Application.StartupPath + "\\server_selfsigned.pem");
    byte[] certBuffer = GetBytesFromPEM(pem, "CERTIFICATE");

    MessageBox.Show(smsRes.Code + " = " + smsRes.Message + " = " + smsRes.Status);
    catch (Exception ex)
    MessageBox.Show(ex.Message);
    Thanks in advance.
    Best Regards,
    Manoj Gupta.

    Hi,
    This issue might be due to the invalid .pem certificate file.
    Make sure to include the beginning and end tags on each certificate.                   
    The result should look like this:                
    -----BEGIN CERTIFICATE-----
    (Your Primary SSL certificate: your_domain_name.crt)
    -----END CERTIFICATE-----
    -----BEGIN CERTIFICATE-----
    (Your Intermediate certificate: DigiCertCA.crt)
    -----END CERTIFICATE-----

  • SAP talking to another sever that is load balancing (with a content switch)

    Hi All,
    We are retrieving some files from an external server in SAP from an ABAP report using HTTP. The external server is also load balacing on 3 servers. There is a content server (proxy server) which carries the sap request to one of the three servers.
    We are able to retrieve the files when we directly connect to one of the three server, However when SAP calls the content server, we get a HTTP code error -404 Status - Not found. Here is the excerpt of code where this error is coming up-
    CALL METHOD w_http_client->response->get_status
    IMPORTING
    code = lv_http_code
    reason = lv_status_text.
    The external server (content server) is supposed to be transparent and thus SAP should be able to connect. But this does not happen.
    Any ideas?
    Thanks in advance! Liz

    We are now connecting SAP directly one server since we could not connect to the content switch.
    Thanks, Liz

  • Cisco Content Switch 11503

    Directed towards any users of this product line out there.
    I have a client who is on the older hardware platform (11100);. and is

    outsntanding questions that i'm needing to confirm on the 11503
    - Source NAT - is this required to always be on? for marketing, reporting and debugging purposes, we're wanting to ensure we can have the client's original ip address preserved once request hits web/app, not rewritten at the content switch.
    - sessions - any concerns running up to 30 - 50k of simultaeous sessions on
    the 11503? require the the addt'l session accel modeule?
    thanks for the input.
    > Byron
    > www.kennedytechgroup.com

    Byron,
    source nat is not a requirement of the CSS.
    It depends how you design your network and where you place the CSS.
    If you do not want source nat, make sure the servers are placed behind the CSS and that the path from server to client always goes through the CSS.
    For the amount of connections, each module can handle up to 200k concurrent connections.
    So, the CSS with only 1 module should be ok.
    Gilles.

    If you updated your existing account then try logging out of it on the iPhone by tapping on the id in Settings > iTunes & App Stores and then log back in and see if that 'refreshes' the account on the iPhone. If you created a new account then any content that you purchased/downloaded via the old account will remain tied to that old account, and only that old account can download updates to its apps.

  • Switch sending tcp traffic to incorrect interface

    Need help diagnosing a layer 2 networking issue. We had a report from an end user of slow file server access from his computer but local applications were responding normally. No one else was having issues in his area. Port mirrored the employees access port (Gi1/0/33) and noticed traffic from another computer crossing onto his port. Our design is to have one computer per port. This traffic was not intended for his computer as it was another employee opening and closing files on the file server (file server located on another switch). Checked MAC address table and his MAC address was the only one associated on the port. Traced the 2nd employees MAC address to a neighboring port (Gi1/0/35). Only MAC address associated on Gi1/0/35 was the 2nd employees. Cleared the mac address entry for Gi1/0/33 only and the extra traffic was eliminated immediately. 
    Why would a switch send tcp traffic to a port that a client does not communicate on? I asked the second employee if they noticed any issue in accessing the file server and none were reported.  Switch is a 3750x with version 12.2. 

    I've been double checking everything this morning and I feel we were not attacked. All the MAC addresses in my capture are valid system addresses. ISE does not show any authorized machines attempting to connect to the switch. We have DHCP snooping enabled throughout the organization. That was a great article to learn from though.
    I've included a visio of the setup and a snippet of the wire capture and arp/mac tables as were captured during the incident. Traffic from the fileserver intended for employee 2 was flooding the port employee 1 was connected on. The destination MAC address of the packets were not meant for employee 1. 
    Default config for both ports:
     switchport access vlan 101
     switchport mode access
     ip access-group ACL_DEFAULT in
     authentication event fail action next-method
     authentication host-mode multi-auth
     authentication open
     authentication order dot1x mab
     authentication priority dot1x mab
     authentication port-control auto
     authentication violation restrict
     mab
     snmp trap mac-notification change added
     snmp trap mac-notification change removed
     dot1x pae authenticator
     dot1x timeout tx-period 10
     spanning-tree portfast
     spanning-tree bpduguard enable
    Am I missing something? Was this an attack? Was it a fluke? 

  • Two load balanced server sending requests to external system on different protocol

    Hi,
    I have two loadbalanced OEG servers (server A and server B) with same endpoint configurations in envsetting.props. But when requesting the service, it is creting different URI in both servers. In one of server (server A)it sets URI with following details :
    DEBUG   30/Mar/2015:07:29:34.356 [92b0e940]     Set host='abc.tdc.dk'
    DEBUG   30/Mar/2015:07:29:34.356 [92b0e940]     Set port='80'
    DEBUG   30/Mar/2015:07:29:34.356 [92b0e940]     Set scheme='https'
    and fails with following error : ERROR   30/Mar/2015:07:29:34.370 [92b0e940]         [SSL_connect, 0x1220]: error - SSLv2/v3 read server hello A.
    However another server (server B),sets URI as :
    DEBUG   30/Mar/2015:07:29:34.356 [92b0e940]     Set host='abc.tdc.dk'
    DEBUG   30/Mar/2015:07:29:34.356 [92b0e940]     Set port='80'
    DEBUG   30/Mar/2015:07:29:34.356 [92b0e940]     Set scheme='http'
    and successfully processes the request.
    So can you please help here to know even if we are using same endpoints configuration (abc.tdc.dk ) and port (80) on both the servers , then why the URL is set as http on one of server and https on another.
    Thanks !!!

  • Citrix and Content Switches

    I'm curious if anyone is using the Cisco Content switches to load balance traffic/sessions across a citrix server farm. Any luck and what type of load balancing method did you use? Round robin? Response time? And do these methods REALLY work with Citrix applications/servers for appropriate load balancing?

    I just load balanced two Citrix servers using Cisco CSS11150 load balancing switches. Because Citrix uses login for each user, load balancing required stickyness. I load balanced using cookies. This works great. You need to configure the cookie string in the service. You need to configure prefix and length in the content rule. There are several ways to load balance using cookies. The server needs to set the cookie in the first reply back to the client.

  • CSM-Content Switching Module

    Hi All,
    How to shutdown Content Switching Module in Cat 6500 switches ? I want to shutdown only CSM-Module without disturbing Chassis.
    Can anyone please send me the command on that ?
    Highly appreciate your valuable reply.
    Thanks,

    Hi,
    Assuming you are using IOS, you can power-down a module in a 6500 chassis using the command
    "no power enable module " in global config mode where is the slot number of the CSM.
    If you are using CatOS then the command would be:
    "set module power down "
    The CSM should be hot-swappable so you should be able to just pull it out of the chassis, but I think that is a bit vicious if you only want to shut it down.

  • Content switch "stickiness"

    I manage a content switch version: sg0810106. I have a customer that has the following requirements:
    The user connects via port 8080 to a VIP on the CSS and the CSS provides them with an Arrowpoint cookie for stickiness. From there If the customer picks CAC authentication, a new session is opened on port 443 to the same VIP on the CSS. The application requires that they be mapped back to the same server they were communicating with on port 8080 to complete the authentication process. The Arrowpoint session cookie is only good for the 8080 session, so the CSS will not use it to map them back to the same server. There are 3 servers mapped to each content.
    Is there a way to map a user back to the same server they were mapped to on a different port?
    Thanks for the assistance!
    Thanks!

    Are you terminating SSL at the CSS at all?
