Call Manager 6.1 network problems

I have a problem with my network drops continually calls phones or freezing.  Its States CM low features disabled.  We lose calls, phones are freezing intermittently.

Here is the hardware configuration: MCS-7828-H3

Platform Type 7828 3 H

Series MX282400CM

OS active 6.1.5.10000 - 10

RTMT shows opt-out phones, but I don't see all devices lose connectivity with the exception of some packet losses minimal for call manager.  No other error not reported in to any device Cisco syslog for example, ping sent to all major network devices have 0 packets lost over the weekend, but 250 on 20 000 ping on the call Manager server is lost.  I replaced the cables, cords and moved from the ports of the switch with no resolution.

CPU has never been higher than 24%

Virtual memory never higher than 30%

Active and Inactive partitions are 15% of disk space.

We have a 2nd NETWORK adapter on the server, but I can't configure this 2nd NIC as a stand-alone connection for the call Manager server, than as a failover for 1 NIC.  Does anyone know how to configure this 2nd NIC to host all these servers IP services?  Is there a way to replace the NETWORK card on those servers (not on site and have yet to open this box upwards) or do I have to replace the entire server?

Does anyone have any other suggestions on where to take my troubleshooting?

Thanks for all the tips!

Steve

Please see below, your right in thinking this could be a faulty network card, cable, I suggest you also to search in your STP configuration.

Error Message RTD-1-ADDR_FLAP [tanks] [dec] base10 relearning / min

Explanation normally, MAC addresses are learned once on a port. Sometimes, when a switched network RECONFIGURES, due either manual or STP reconfiguration, addresses learned on a port are relearned on a different port.  However, if there is a port anywhere in the switched domain that is loop over itself, addresses will jump backwards between the real port and the port that is in the path to the rear port loop. In this message, [tanks] is the interface, and [dec] is the number of addresses being learned.

Recommended action determine the actual path (port) to the MAC address. Use the ethernet controller of debugging command EXEC addr the privilege of seeing the other path-port on which the address is redisplays. Go to the switch that is connected to this port. Note that the show cdp neighbors command is useful to determine the following switch. Repeat this procedure until the port is found who receives what it transmits and remove this network port.

Link to Error Message-RTD-1-LINK_FLAP [tanks] down/up [dec] times / min

Explanation this message means that too many events from the bottom up link was noticed on this interface: [tanks] is the interface, and [dec] is the number of times that the link goes up and down. This could be the result of reconfiguring the port, or it might mean a faulty device at the other end of the connection.

Recommended action if a person is to reconfigure the interface or device across the interface, ignore this message. However, if no one manipulates the interface or device at the other end of the interface, it is likely that the Ethernet transceiver at one end of the link is faulty and must be replaced.

  • Strange problem with call manager and call before all

    Not sure whether this post about unity for or CCM. I will post on both. I have a main number customers dial in. When they call this number and they do not get a response, it passes to a call handler. This call handler has an option of entry of the appellant 3. If they hit option is three transfers to an IP phone on Call Manager who is assigned to the CFA for this cell phone to people. Everything works except when the call is sent to the PSTN it sounds for time and then disconnects. This number can be called directly from the system with no problem. The cause of the disconnection on debugging is the following: because I = 0x80FF - error of interconnection of networks; not specified. Please help if you can.

    I assume you are using version transfers here. You can give it a whirl with supervised transfers?

  • network problems, QNetworkAccessManager?

    Hello, I have a strange problem with networking and any help would be appreciated to greately.

    I have this code:

     MyCustomNetworkClass network;
    
         // Set request parameters
         QMap params;
         params.insert("username", userEmail);
         params.insert("password", password);
    
         network.initializeRequestParam(params);
    
         network.makePostRequest("Login");
    

    Inside the makePostRequest function MyCustomNetworkClass' are, I call the following method:

    mNetworkAccessManager->post(req, postData.encodedQuery());
    // where "req" contains parameters set using the "initializeRequestParam" function as above.
    

    and then in MyCustomNetworkClass requestFinished method, I'm waiting for the response from the server:

    void MyCustomNetworkClass::requestFinished(QNetworkReply* reply)
    {
    ....     // But it seems the program never gets here ??? Why ??
    }
    

    Can someone please identify where could be the problem? PS. I managed to connect signal and slot in the constructor of MyCustomNetworkClass, for example, like this:

     bool result = connect(mNetworkAccessManager, SIGNAL(finished(QNetworkReply*)), this, SLOT(requestFinished(QNetworkReply*)));
    

    I solved this problem in a very strange way. The code I wrote before:

     MyCustomNetworkClass network;
    
         // Set request parameters
         QMap params;
         params.insert("username", userEmail);
         params.insert("password", password);
    
         network.initializeRequestParam(params);
    
         network.makePostRequest("Login");
    

    I replaced it with:

     // Network Manager object
         MyCustomNetworkClass *network = new MyCustomNetworkClass();
    
        // Parameters for user login
        QMap params;
        params.insert("username", userEmail);
        params.insert("password", password);
        params.insert("deviceId", QUuid::createUuid().toString());
    
        // Set parameters
        network->initializeRequestParam(params);
    
        // Issue post request to the server
        network->makePostRequest("Login");
    

    and now, the requestFinished is called. Why is this case? Any ideas?

    PS. I have a little different problem, in the same place, I add:

      bool res = QObject::connect(network, SIGNAL(signalSuccess(QVariantMap)), this, SLOT(successSlot(QVariantMap)));
        Q_ASSERT(res);
        Q_UNUSED(res);
    

    But this slot is never called (..)

    Although as I said the requestFinished gets now called successfully and there this method implemented inside, which should call the above location:

          emit signalSuccess(data);
    

    Any help?

  • ESXi network problem

    I have a strange problem of networking with ESXi, my infrastructure is described below:

    I'm under vCenter 5.5 on a VCSA (5.5.0 update 2d, Build 2442330). The environment is a mixture of ESXi 5.1 (especially U2) and 5.5U1a. We have 1 primary site with 5 sites all remote connected via GRE VPN tunnels, The VCSA is in the main site, each remote site has at least 1 ESXi server managed by the VCSA. Each remote site has independent internet so for each site, the basic router (which ends the GRE VPN) routes inside networks (essentially 10.0.0.0/8) through the tunnel and has a default route to the local firewall. ESXi boxes that are not configured with the router as the default gateway, none of the custom static routes have been added to ESXi.

    Two of my remote sites (a site has two servers ESXi, the other has a site) ESXi servers keep losing contact with vCenter. Nothing else on these networks is never a problem to talk to the main site, including talking to the VCSA. Three servers are different versions of 5.1. Here's what I've done for troubleshooting:

    1. ESXi can ping on virtually any host through the tunnel to the main site with the exception of the VCSA.
    2. I isolated my network management in ESXi to a physical NETWORK card and made a SPAN on the switch port, a capture of packets revealed that when the rattling of the VCSA ESXi put the packet on the wire with a destination MAC of the firewall. For all the other hosts on the main site of subnet ESXi sends the packet with a destination MAC address of the core router. Packet capture on ESXi itself (using tcpdump-uw) shows the same thing.
    3. The ARP tables on all hosts show correct MAC addresses for the router base and the firewall.
    4. Make a "vmkping - I vmk0 - N < core router > < VCSA >" succeeds (destination MAC is correct in this case).
    5. Add a static route to ESXi to the address of the VCSA force it to the top of base does not work, ESXi continues to send the packet to the Mac static routes these firewall have been removed after the failed test of workaround.
    6. Restart the host will solve the problem for a short time.

    Some info:

    These three server 1 is an IBM x 3300 M4 using Intel I350 GB network cards, the other two are R620s from Dell. The R620s each have 1 4-port Broadcom BCM5720-1 4 Intel 82580 ports. IPv6 has been disabled on all three hosts. Right now vmk0 is linked to an Intel NETWORK card on three servers, but barely I started to watch it, so I don't know if we saw the problem with vmk0 with a Broadcom.

    The Dells are inherited, so we have not done installs it but I reinstalled one of them yesterday (it was 5.1 U2 I reinstalled 5.1 U3) at the request of support for VMware. Support noted that the firmware and drivers were outdated and did not meet the HCL for those who have been updated when I reinstalled.

    IBM has been purchased and installed by our care last summer, firmware and drivers correspond to this LIST with the exception of the version of the BIOS that is a future release (it corresponds to the HCL for 5.5).

    I have a pension case, SR 15633456803. Initially, they tried to blame the network. Although it is clear to me that this is not a network problem, I put a case of Cisco in any way. Cisco has quickly threw the evidence I had gathered and made the same determination. The only way that this could be a network problem is with ProxyARP. ProxyARP is disabled on my firewalls, ESXi has correct ARP tables and when you talk to anything on the main network, in addition to the VCSA it sends the packet to the MAC address so clearly not a question of ProxyARP. At this point VMware said essentially that they are running out of ideas. I hope my reinstalled host stay online for more than a week, then I'll reinstall the other two hosts and call it a day if all goes well, but I'm preparing for the possibility that may not happen.

    We never seen anything like this or have any ideas?

    I understand the problem, ESXi does not correctly release the generated ICMP redirects. You can force the issue by restarting the vmk0 interface (or any port of kernel VM is your management interface) VMware KB: Internet control management protocol redirects, because a permanent fix I will disable ICMP redirects on my routers.

  • Vista unidentified network problem

    My HP G60 laptop under vista home premium got an "unidentified network" problem and not able to get on the internet. I even tried to reinstall vista to factory default, still the same problem with my wireless router.

    Spec:

    -HP G60 laptop computer, running vista Home premium 32-bit, with 3 GB of RAM

    -Belkin router

    -I am able to connect via a fine wired line but with a Wi - Fi, it shows constantly 'unidentified network', even if I changed the Private mode in network and sharing Center.

    -J' tried the following: listed an SSID different router, reset the router by default, to reinstall vista, tried other mechanisms, such as specified in the forum, with no difference

    -When you configure the router, I have clone MAC of the laptop to the router to get the connection with Comcast, has done that with network cable connected, internet connection worked well after cloning.

    -no virus SW installed.

    Any suggestions on what might be the solution here? Thank you.

    Hello

    It seems that something is blocking the wireless to connect to the wireless router and to obtain a valid IP address.

    Maybe this can help.

    These steps and tell us where is the breaking point.

    Check the Device Manager for the wireless card valid entry.

    http://www.ezlan.NET/Win7/net_dm.jpg

    If there is no valid entry, remove any entry from fake and re - install the drivers for the wireless card.

    Check network connections to make sure that you have a network icon/entry wireless connection, and that the properties of the icon (right-click on the icon) are correctly configured with the TCP/IPv4 protocol in the properties of network connections.

    http://www.ezlan.NET/Win7/net_connection_tcp.jpg

    ------------------

    The wireless card drivers much also install utility wireless of the seller.

    Make sure that if there are teas from Wireless Utility of seller does not work with the native Windows wireless utility (Service WLAN).

    ----------------

    Make sure you firewall No. preventing / blocks wireless components to join the network.

    Some 3rd party software firewall continue to block the same aspects it traffic Local, they are turned Off (disabled). If possible set up the firewall correctly, otherwise totally uninstall and get rid of its remaining processes that permit the own local network traffic flow.

    If the 3rd party software is uninstalled, or disables, make sure Windows native firewall is active .

    party like Hello and NetMagic 3rd network managers can block local traffic too.

    ---------------------------

    Stack TCP/IP work should look like.

    Right-click on the wireless network connection card, select status, details and see if she got an IP address and the rest of the settings.

    http://www.ezlan.NET/Win7/status-NIC.jpg

    Description is the data of the card making.

    The physical address is MAC of the card number.

    The xx must be a number between 0 and 255 (all xx even number).

    YY should be between 0 and 255

    ZZ should be between 0 and 255 (zz all the same number.)

    The date of the lease must be valid at the present time.

    * Note 1. IP that starts with 169.xxx.xxx.xxx isn't valid functional IP.

    * Note 2. There could be an IPv6 entries too. However, they are not functional for Internet or LAN traffic. They are necessary for Win 7 homegroup special configuration.

    ---------------------------------------------------

    A message in the small window that says connected wireless doesn't means that you are really a valid functional connection.

    Above everything is OK, you must be able to connect to the router.

    Connection to the router means that you can enter the IP of the router base in an address bar in one go, being able to connect and configure the router menus see.

    If it doesn't connect to the router, journal newspaper from any computer that can connect to the router wirelessly with a wire, disable wireless security, make sure that the wireless SSID broadcast is enabled and try to connect with no. wireless security.

    Enable security wireless after you eat to make a functional connection.

  • What is the procedure of upgrading since version 7.1 of CUCM (MCS Server) call manager to version 10.2 of CUCM (on the server of the UCS)

    Hello

    What is the procedure to upgrade the call manager since version 7.1 of CUCM (MCS Server) to version 10.2 of CUCM (on the server of the UCS), please let me know the steps to what would be the backup procedures and upgrades.

    Concerning

    Gerard

    I suggest reading this guide to make sure that you have prepared your environment to support the first 10.x. The link below also contains the path to upgrade to 10.0 (1).

    One of the ways to do this is:

    1 / apply cooling cop upgrade file on all servers in the cluster.

    2 / upgrade the cluster to 8.6 (2). Make a backup of the cluster.

    3 / build a cluster of servers 8.6 (2) on the virtual machines and assign them the same host name and the IP address of the cluster hardware. (You may need to keep these on a separate network until turn off hardware machines)

    4 / restoration of the backup of the pile of material on the VM cluster.

    5 / upgrade cluster VM to 10.0 (1).

  • Strange when network problem the ESX servers powered

    Hello.

    First of all, do not know if this is the right forum but I hope you can help.

    I have a question where to chance the firewall stops responding during a small number or a host/pcs/physical server randomly on my network. This problem started since the launch of VMware and two ESX servers. I think that its a problem ARP as erasing the NIC ARP cache on the windows computer that has trouble to the solve the problem temporarily. A permeant fix is to cut the ESX servers, which is obviously not a solution.

    Ive changed the firewall's Pack but have the same problem. Any thoughts on what to check on ESX to see what is the cause? My ESX servers currently have a unique NETWORK card on the LAN vSwitch for simplicity and a distinct vSwitch for 10 gb iSCSI, which is directly connected to the San. Very simple.

    Thank you

    Ive found my problem.

    My SAN, a HP MSA2040 manages a network of 192.168.200.x for internal use according to HP support. Even if id changed IP address of management to another network that it stills works this range. Therefore, the map was updated to the ARP tables and sending request to the bad MAC/IP who just happened to be the IP address of my gateway to some network hosts. Crazy stuff.

  • Can I migrate a virtual computer to a new family of CPU? -Cisco Call Manager PUB/SUB

    I currently have 2 host VMware ESXi 4.1:

    1. Dell PER905 - running 16 x 2.39 GHz (core) CPU / Quad-Core AMD Opteron (tm) Processor 8378 (processor type)

    2 cisco UCS C260 M2 (BASE-2646) - running 20 x 2,393 GHz (core) CPU / Intel (R) Xeon (R) CPU E72870 (processor type)


    The main objective is to move 2 VM of the Dell host to the host of Cisco, the reason is because Cisco Support said that the virtual machine requires an Intel and not AMD they are currently.  I currently have a Publisher Cisco Call Manager and Call Manager subscriber residing on the host of Dell, they are constructed (non - OVF) on this machine some time ago.  We started to have problems with them and ultimately Cisco indicated above.


    A few questions come to mind, can someone please shed some light on them for me?

    1. can I migrate these 2 AMD to Intel VM, without her damage/destruction of the virtual machine?  What that is the answer may be, can you explain to me the why?  The answer to the migration of the CPU is dependent on the guest OS or what?  I ask because I did this successfully on a Windows Guest OS virtual machine, but I guess it is that Cisco makes me hesitate/question.

    2 would it not be better to each virtual machine rebuilt on the new host, rather than through migration for the purposes of the CPU?

    3. What is the recommended method to endorse these VM, before proceeding with the migration?  I'm not talking about save data in the call manager for reasons that I will perform a backup it first.  I ask more along the lines of - for the love of the virtual machine itself.

    You should be able to perform a cold migration. The concern is the guest operating system level.  The Cisco device is probably a Linux distro.  The distribution must use the AMD64 instruction set (Intel 64 compatible) and theoretically should migrate fine.  However, if the guest what OS was improved the AMD CPU instructions, he can expect these features when you restart.  We have at least a virtual computer in our environment that we need to stick to a certain family of Intel processor because the software license dig and binds to it, but this is the only scenario that I have met.

    2 would it not be better to each virtual machine rebuilt on the new host, rather than through migration for the purposes of the CPU?

    I feel better on the redeployment, but if the migration is successful and applications run stable, then you reaped just the benefits of virtualization.

    3. What is the recommended method to endorse these VM, before proceeding with the migration?  I'm not talking about save data in the call manager for reasons that I will perform a backup it first.  I ask more along the lines of - for the love of the virtual machine itself.

    You could do something as simple as the cloning of a copy.  Depending on how you are approved for vSphere, you can have the POS to back up your virtual machine.  You can also use a tool such as VMWare Converter or Veeam Backup and replication. Given the importance of these virtual machines, I would get at least 2 backups of different type.  You should be able to validate any backup with VMWare Workstation prior to migration.
