WLC 5508 : session disconnected when one lag-port is down.

Hello,
I have a WLC 5508 ( version 6.0.182).
When the port1 and port2 are connected ( The switch is configured with a etherchannel in forced mode) everything works fine: There is traffic on the 2 ports.
When I disconnect one of the 2 ports, I can still ping outside with my PC client, but all my tcp sesssions goes down and I even cannot restart my session. The only way I found  is to do a "Disconnect / Reconnect"  on my  PC  wireless connection.
Do you know this probleme ?
Is it a way to avoid it ?

CSCth12513 LAG fail-over does not work on CT5508
This bug is fixed in the special release available through TAC : 6.0.199.157 and 7.0.xxxx
Hope this helps.

  • Wlc 5508 get error when use port-channel

    We have two wlc in the system 5508 and 4402.
    we config HA for 2 wlc, both wlc enable LAG
    When I connect 2 interface  of 5508 to 2 interface (in a port channel mode on, trunk, dot1q) of a
    couple of VSS switch, I cant management 5508 through web any more, and I still can do with 4402.
    If I  shutdown 1 port int the port-channel, it work well.
    Do you know what happen ?
    Thanks
    Duyen

    hi Scott,
    We have VSS ( 2 x 6509) trunk with (2 switch 4506).  one port of wlc4402 connect to one port of one swith 4506.
    2 ports of wlc 5508 conect to 6509, each port connect to one switch 6509.
    the config in VSS switch like this:
    interface gig1/1/1
    switchport trunk encapsulation dot1q
    switchport mode trunk
    channel-group 500 mode on
    interface gig2/1/1
    switchport trunk encapsulation dot1q
    switchport mode trunk
    channel-group 500 mode on
    etherchannel load-balancer src-dst-ip
    ( I dont see this command in running config)

  • WLC 5508 - Clients disconnecting

    I am running WLC 5508 7.2.111.3 with some 2602i AP.
    Last week one user reported his new macbook pro 2013 was encountering connectivity issues.His older macbook pro 2009 was working perfectly.
    The user is sitting in the middle of 2nd floor having equal distance from second's floor access points.
    The problem is that his Macbook pro 2013 was persistently trying to associate with 3rd's floor Access Points. Whatever i tried to do (deauthenticate user,rebooting 2nd & 3rd floor APs) the connection was persistent to 3rd floor Access Point. Even when i tried to install an Access Point in the user's office his Macbook Pro 2013 refused (!!!) to leave 3rd's floor Access Points.However his Macbook pro 2009 was always connected to the nearest Access Point (either to 2nd floor Access Points or to the newly installed access point in his office).
    This week i had two visitors in 4th floor reporting that their Laptops (Sony Vaio) were doing very slow with the wireless.
    When i tried to troubleshoot i found in the controller that their laptops were associating with 4th floor Access Points and after a minute they were disconnected and trying to associate to Ground Floor (!) Access Points. Of course they couldn't establish a connection and then associated again with 4th floor access points and after a while disconnected and trying to associate to Ground Floor Access Points
    I tried to debug client with Sony Vaio and saw in the controller the following message
    *apfMsConnTask_7: Mar 24 10:42:15.473: %APF-4-INVALID_ACTION_CATEGORY: apf_wme_utils.c:5481 Could not process 802.11 Action. Received Action frame with invalid category field(not supported by controller) from client. Mobile:*********, Category:7.
    I also see a lot of these messages for other clients.
    *apfMsConnTask_3: Mar 19 12:03:54.243: %APF-4-ASSOCREQ_PROC_FAILED: apf_80211.c:5275 Failed to process an association request from c8:6f:1d:24:0e:7d. WLAN:5, SSID:************. mobile in database timed out.
    Am i hitting any bug similar or equal to CSCue53980?

    have you tried with open authentication ( no security ) ? Check if client is able to associate then

  • Archive REDO When One RAC Node is Down

    I have a question about how redo log get archived when one of the instances in a two node RAC cluster is down (not open, not mounted).
    For example, let's assume instance1 was shutdown and only instance 2 is running.
    I have 6 redo logs:
    <font face="courier">
    SQL> SELECT GROUP#, THREAD#, SEQUENCE#, STATUS FROM V$LOG;
    GROUP# THREAD# SEQUENCE# STATUS
    1 1 3390 INACTIVE
    2 1 3389 INACTIVE
    3 1 3391 ACTIVE
    5 2 3886 INACTIVE
    4 2 3887 INACTIVE
    6 2 3888 CURRENT
    </font>
    If I run the following statement what will happen?
    <font face="courier">
    SQL> ALTER SYSTEM ARCHIVE LOG CURRENT;
    </font>
    The documentation says +Specify CURRENT to manually archive the current redo log file group of the specified thread, forcing a log switch. If you omit the THREAD parameter, then Oracle Database archives all redo log file groups from all enabled threads, including logs previous to current logs. You can specify CURRENT only when the database is open.+
    Would Oracle archive sequence# 3391 from thread 1 even though the instance is not open?

    When your instance are not working, it means that it doesn't have any CURRENT redo log. So when you issue switching logfile - it launches archiving only current redo log, for working instance only. That 3391 redo log is not current, it has Active status, that means that it could be needed for recovery purpose, but it had to be archived earlier.

  • Session disconnects when executing procedure

    For some reason when I execute my procedure I get a ORA-00603: Oracle server session terminated by fatal error. When I comment out the section of code below, the procedure executes without issue. I've run an Explain Plan on this SQL, but the cost is really low. I suspect it has something to do with the table that is accessed across DB Link. Any ideas how to resolve?
    DB version: Oracle 10.2.0.3.0
                    select UPPER(fcc_emp.EMP_LST_NM||', '||fcc_emp.EMP_FST_NM) emp_name,
                           hr.emp_email_ad
                      INTO v_fa_name,
                           v_email_addr                    
                      from table_A slea_emp,
                           table_B fcc_emp,
                           table_C@remote_DB hr
                     WHERE slea_emp.empid = fcc_emp.emp_id
                       AND slea_emp.eligible_ind = 'Y'
                       AND fcc_emp.emp_9dig_id = hr.emp_id_cd   
                       AND slea_emp.empid = v_xml_rec.EmpID
                       AND slea_emp.slea_year = gv_slea_year;  

    Don't look at the cost in an Explain plan. But show us the plan.
    You can also try to rewrite the statement
    select UPPER(fcc_emp.EMP_LST_NM||', '||fcc_emp.EMP_FST_NM) emp_name,
                (select min(hr.emp_email_ad) from table_C@remote_DB hr where fcc_emp.emp_9dig_id = hr.emp_id_cd) emp_email_ad
         INTO v_fa_name,
              v_email_addr
         from table_A slea_emp,
              table_B fcc_emp
         WHERE slea_emp.empid = fcc_emp.emp_id
         AND slea_emp.eligible_ind = 'Y'
         AND slea_emp.empid = v_xml_rec.EmpID
         AND slea_emp.slea_year = gv_slea_year;   but this would return only one email address per name. And sometimes even none.

    thanks for help

    Hi,
    Any server in a DAG can host a copy of a mailbox database from any other server in the DAG. When a server is added to a DAG, it works with the other servers in the DAG to provide automatic recovery from failures that affect mailbox databases, such as a disk,
    server, or network failure.
    We can undestand more information from this document.

  • One USB port isn't working...

    Hey,
    I just realised that one of my USB ports isn't working when I plugged in my mouse... Should I be very concerned about this?
    I live in a really remote community (ie no stores anywhere closer than a 3 hour plane ride away) and can't bear the thought of living without a computer for several weeks if I send it to Apple to be repaired.
    Could it be a sign that there's something else going on? Is is expensive to fix?
    Thanks!!

    Welcome to the Apple discussions.
    When one USB port isn't working, often a Power Management Unit (PMU) reset will fix it. Follow these directions: http://docs.info.apple.com/article.html?artnum=14449

  • Issues with processing messages on one receive port causes problems on all the receive ports that are on the same handler

    Greetings,
    An integrator installed biztalk in our environment to process the hl7 message flow between their source application(s) and several receiving applications. We've had problems with this set-up for a while now because some receiving applications sometimes have
    problems processing the messages. Be it either because there's problems with the server that processes the messages of a certain port or because there's problems with the software/daemon/service that needs to process these messages.
    The main problem with this, is that the receiving end of this isn't under our control nor under control of the integrator, but when one receive port isn't processing their messages for a while it causes a problem with all the receive ports that are on the
    same handler. So other receive ports start noticing a slow-down of their incoming messages until after a while nothing gets through anymore.
    What is the best practice to prevent these kind of problems? Should we just create a handler for every receive port? Because that seems a bit overkill.
    Thanks in advance.

    What do you mean exactly with this question?
    "Can you provide some more detail like BizTalk the receiver? "
    The adapters are mainly file and MLLP, the MLLP adapters are already seperated from the file adapters (a handler for MLLP and a handler for file).
    The problem with all the receive ports is that when one receive port isn't processing its messages (usually caused by the software processing the messages) the other receive ports on the same handler receive their messages/files a lot slower. If for any
    reason the problem isn't fixed soon, the other receive ports on the same handler actually stop receiving any messages at all.
    Isolating the receive port that causes the problems like la Cour suggested can work, but next time it might be another port that experiences this issue. So we are looking for a way to make sure the whole message flow isn't hindered by one port (whichever
    port) that can't process its messages. Or rather by one receiving software that can't process its messages.

  • Health Service Heartbeat Failure Alert for Generated when one Management Server Down,

    Hi,
    I have Two Management Server, every one manage about 100 server, when one Management Server goes down unexpected, I receive 100 Alert for 100 Server Health Service Heartbeat Failure.
    My Question, why when the Management Server down, it send that all Managed agent Health Service Heartbeat Failure?
    Is there a way to change this?

    SCOM 2012 agent will autofailover when primary server is down. You can check the failover management server by using the following powershell cmdlet:
    #Verify Failover for Agents reporting to MS1
    $Agents = Get-SCOMAgent | where {$_.PrimaryManagementServerName -eq 'MS1.DOMAIN.COM'}
    $Agents | sort | foreach {
    Write-Host "";
    "Agent :: " + $_.Name;
    "--Primary MS :: " + ($_.GetPrimaryManagementServer()).ComputerName;
    $failoverServers = $_.getFailoverManagementServers();
    foreach ($managementServer in $failoverServers) {
    "--Failover MS :: " + ($managementServer.ComputerName);
    Write-Host "";

  • WLC 5508 issue with 4 ports in portchannel

    Hi,
    We have one WLC 5508 and LAG is enabled on it but when we connect 4 cables to a distribution switch only 3 links are sending and receiving traffic and the 4th one is up with outgoing traffic from the distribution switch to WLC but nothing incoming.
    Some APs went down and refuse to be registered back to the WLC. when we shut down the 4th port everything is back to normal.
    the etherchannel config is identical and I can see all ports are active and not suspended :

  • WLC 5508 LAG and CAt 3750 cross stack

    Hello,
    I would like to use the LAG feature on my 5508 WLCs and connect each of them to two different port of a 3750 stack using cross stack. Do you think it will work?
    Cisco suggests not to connect different LAG ports of a WLC to different CAT3750 but it's not clear if it was referred to different standalone 3750s or to a stackwise of 3750s.
    Tnks all
    Johnny

    The HA kicks in when the primary looses gateway, do a small test, keep a continuous ping to WLC  from its gateway as source and break one of the link in the LAG and see if you drop any packet ?

  • WLC 5508 - Error When Uploading Webauth Bundle

    Currently have a WLC 5508 running 7.4.110.0.  I'm trying to upload (download) a webauth bundle to the controller from the web interface and am getting an error.  I've tried using FTP, SFTP and TFTP and get a different error with each.  When I started out with this, I was using a modified login.tar.  Thinking this was the problem, I switched to using the login.tar file included with the Web Authentication Bundle version 1.0.2 downloaded from the Cisco site.  This file fails with the errors below.  Does anyone have suggestions as to what I'm doing wrong?  Is this is a known bug in this version of the software?  Thanks!

    Hi,
    1. Did you used  PIcozip to compress your webauth bundle?
    2. Did you try only with one laptop , if yes then try to use other one.
    3. Just try to upload default webauth bundl from cisco to wlc and show the result to us.

    HI
    We have cisco WLC 5508 in our network and right now ,this WLC is connected to two ports of each core switches.Both CORP and GUEST SSID are configured on this WLC.
    Now we want to segregate the trafffic og GUEST to on core switches from WLC. SO my question is ,how can we achieve this without using guest anchor controller ?
    Can i use one interfcae cisco WLC 5508 and connect it to the firewall or any device ?
    Thanks

    Hi
    Thanks ...I am using WLC as a DHCP server for Guest.
    So  i want to know ,is there any requirement that GUEST subnet should be pingable from WLC management IP address.
    my topology is here...
    Corp network and management network are reachable however management metwork is not pinagble from guest netowrk.
