or TX drops is greater than 0. Resolving the problem 1) If you are running a 4195

(XI52, XB62) and have issues with eth7/eth9 interfaces please review the technote DataPower Blade (M/T 4195) 10 gig interfaces, eth7 and eth9, are not working properly. 2) If you are running a 9235 (XI50, XS40) with an XG3/XG4 hardware accelerator and are having issues with eth1/eth2 interface negotiation speeds please review the technote Unable to set the speed on ETH1 and ETH2 on the 9235/9004 xg3 and xg4 IBM WebSphere DataPower Appliance. 3) Check and make sure the interface does not run in half duplex mode, either in the CLI check the speed in 'show int mode' or the mode field in Status->IP-Network->Ethernet Interfaces. Half duplex is represented by the last two characters 'HD'. 'FD' is full duplex and this is the mode you would typically want reported. If an interface is running in half duplex the negotiation mode may be incorrect. 4) Check the cable connected to the ethernet interface, attempt a new cable replacement. 5) Check the port switch and try an alternative port on the switch or a different switch. If problems persist please contact support and provide the information requested in the MustGather: Collecting data on IBM WebSphere DataPower SOA Appliance for networking and connectivity problems technote.

validated even though you would see the Connection Hangup error. The main reason for this error is, Crypto Profile object inDataPowerhave the series of open SSL options which modify the behavior of SSLhand shake, From version 7 DataPower supporting the TLS v1.1 and 1.2 protocols. As we all know SSL is being replaced by TLS due its high security, but most of the servers are still using the combination of SSl v3.0 and TLS 1.0 for the SSL http://www.ibm.com/support/docview.wss?uid=swg21650780 negotiation. There are explicit options available on the crypto profile object to disable the TLS v1.1 and 1.2 if these options not checked then the SSL handshake will take the highest security protocol TLS 1.1 or TLS 1.2 by default and cannot complete the SSL handshake due the server was expecting the SSL v3 and http://datapowerfresher.blogspot.com/2015/04/network-error-connection-hangup-on-back.html TLS 1.0. Solution: Check the Disable TLS v1.1 and TLS v1.2 options. By default they were enabled. If the server is configured with TLS v1.1 and v1.2 capability then you wouldn't find this issue at all.

Shouldn't that be failing?— Nagratz the lock (@Nagratz_aie) June 22, 2016 Let's look at each piece of the question. DISPLAY QMSTATUS CONNS You can use the DISPLAY QMSTATUS command to see how many connections there are currently made into the queue manager. This is a count of the number of applications (or some queue manager processes too) that have made an MQCONN(X) to the queue manager. It is also the same number of responses you should see returned by DISPLAYCONN(*) - if you don't want to count them, find an MQ admin tool that counts them for you. These connections might be local or client connections - both contribute to the total. @Nagratz_aie DIS QMSTATUS shows all the connections made to the queue manager - they are not 1:1 with channels.— Morag Hughson (@MoragHughson) June 22, 2016 To see the local ones use command:- DISPLAY CONN(*) ALL WHERE(CHANNEL EQ ' ') To see the remote ones use command:- DISPLAY CONN(*) ALL WHERE(CHANNEL NE ' ') Client Connections and MaxChannels So having ruled out the local connections what should you think if the number of connections coming in over a channel is more than MaxChannels? As the question asks, "Shouldn't that be failing?" The other thing to remember here is that, since MQ V7, one SVRCONN channel can relay several client MQCONNs over to the queue manager. @Nagratz_aie Remember you can have local conns and you can have several client conns per SVRCONN (check DIS CHSTATUS CURSHCNV)— Morag Hughson (@MoragHughson) June 22, 2016 To see this tak
