• Cisco NTP Sync ISE

  Hi people,

  I was wondering if anyone knows the reason why a Cisco ISE is not synchronized with the NTP server. I am able to ping from ISE servers and wireless controller is properly synchronized.

  Is there something more in addition to time zone and Setup "ntp server"?

  synchronized to a stratum 11 LAN
  correct time less than 11 ms
  vote server each 1024 s

  refid distance st t when poll reach delay offset jitter

  Hi Flavio,

  It happens with ISE and ACS, they synchronize correctly or loses the synchorinization, you can either make no ntp server and ntp again server or you can restart the NTP service. even that sometimes helps

• ESXi 5.1 configured as a NTP server, do not sync with the Local PC

  I have a 5.1 ESXi server configured as an NTP server and a Windows Server 2008 R2 local PC that are not sync.  I understand well, it is not recommended for ESXi, but I read [1] [2] that, whenever an ESXi server is running as a client, it also acts as a server, so I enabled as a NTP client in vSphere by ticking the NTP client, adding some servers to the server list, and then click on run, and I also activated the 123 incoming/outgoing port by adding the shell of ESXi firewall settings.

  I'm pretty sure it isn't a firewall problem.  I completely disabled the firewall on my local PC.  Running "w32tm keyboardists computers: - IP address of the server -" give me the time of the server and running the software NTPQuery gives me an answer back on port 123 of the server time.

  I tried:

  - Date/time settings (right-click on notification area-> set date/time-> Internet time-> set as the IP address of the server) - sync fails (* an error has occurred while Windows timed with - server IP-*)

  - Group Policy Editor (Computer Configuration\Administrative Templates administration\systeme\service Time Service, currently disabled but because I heard this causes problems) - synchronization fails

  - The registry editor (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\W32Time\settings) - synchronization fails

  - Command prompt, using:

  w32tm /config /manualpeerlist:-IP of server- /syncfromflags:MANUAL /reliable:yes /update
  net stop w32time && net start w32time
  w32tm /resync /rediscover
  
  
  

  This updates the registry properly, but the outputs "the computer did not resync because no time data was available."  And when I use the command "w32tm/query/source" the source is always "The local CMOS clock."

  Here is the output from w32tm/query /configuration

  Any ideas?  Thanks in advance.

  Your ESXi server response shows that the leap indicator is 3 and the server stratum is 0.

  This means that ESXi NTP server is synchronized and unable to provide a valid reference time to customers.

  We recommend that you configure your ESXi host with valid upstream NTP servers such as:

  0.vmware.pool.ntp.org,1.vmware.pool.ntp.org and 2. VMware.pool.ntp.org

  as described in the KB article or alternatively your internet service provider NTP servers.

  Although not recommended, you can configure ESXi to allow a reference time by using the own system clock

  If you can not configure ESXi to synchronize to external NTP servers upstream.

  UI, tab Configuration, using software (time setting), properties, Options, and NTP settings.

  Specify "127.127.1.0" as your single NTP server. Don't forget to check the box "restart NTP service to apply the changes.

  then click OK twice to close the dialog boxes. Wait a few minutes for NTP sync, then try your test.

  According to RFC 4330, NTP-SNTP (Simple) customers must not use time in a package of NTP response if the

  stratum returned is 0 (and the leap indicator is 3). Apparently, your client Windows NTP Simple is more

  the RFC.

• features of the client ntp ESXi (interesting compliance requirement)

  Hi guys,.

  I was thrown an interesting compliance of a customer requirement. They demand that all averaged over servers ntp NTP updates (preferably 3) 2 (a particular layer, although I don't think this would have a bearing on the issue).

  Indeed, they want to question several NTP servers, the average of the difference between the updates provided by all servers then drift in that direction. Apparently, this is the normal behavior for the ntp client HP NonStop they use and must find a way to do it on all the other guests.

  I trawled autour and couldn't find an easy way to do this with esxi ntpd uses. The best I could think of would be to have infrastructure ntp sync for that provide customers (esx), but from the perspective of compliance that would not be cut.

  Apparently, it is a common requirement of compliance for the financial houses - anyone otherwise run into that, or have a solution?

  It seems that one of these requirements that no one knows everything

  As usual, all thoughts appreciated and rewarded with points

  The behavior you describe (drift toward the average of the reported servers) is the normal and expected of all implementations NTP appropriate.  (See http://web.archive.org/web/20100331222927/http :// www.sun.com/blueprints/0901/NTPpt3.pdf for an explanation of why this is the case - as part of the illustration on page 9 is one of the best things that you will ever make to understand NTP.)

  As near as I can tell, ESXi provides a fully operational server.  So all what you need to do is add three servers in the service host configuration screen and you will get this behavior.  You can verify the behavior by the running of "ntpq - pn IPaddress" from a local Linux machine against your ESXi host.  This is only an example of what mine looks like shortly after the time servers have been reconfigured and restarted ntpd:

  refid distance st t when poll reach delay offset jitter

  This server has been slower than the actual time of about 1 minute (60 000 milliseconds) and should start to drift toward it once it is synchronized to the top.

  Kind regards

• Machine virtual NTP Time Sync issue... What is the best practice today?

  Hello

  I'm confused, I get conflicting information on the synchronization time

  config to use these days for full P2V' ed infrastructure OK here a scenario:

  about 30 servers migrate and running on aa Infrastructure ESX vSphere 4, vCenter

  4... 2XW2K3 (virtualized) domain controllers the rest of them, a mix of

  DB and member servers of applications using several rolls. No. during the 'better '.

  Practice' wise I do...

  (A) keep the configuration of PDC emulator to retrieve it is time of a

  "A source of atomic time / NTP server, then keep windows time service running.

  and just the rest of the members field sync from there servers

  or I don't...

  (B) disable Windows time Service on all domain members and domain controllers

  Member breaks and have all the VMS recovery there time source NTP

  the host ESX via VMtools.

  Can someone give me a clear answer?  & lt;

• Demon NTP using a lot of cycles CPU

  My MacBook Pro (early 2011) running OS 10.11.4 fonctionnee hot and slow recently.  I turned on Activity Monitor and ntpd (the demon of time network) is constantly to consume 12 to 15% of cycles CPU.  I found an article on the stack Exchange, who said that if you see activity like this on your NTP daemon, it could be a sign that someone used a DRDoS attack.  They suggested defining the demon NTP to refuse incoming network connections - which I do not know how to do.  (I'm on Mac OS firewall).

  I took a sample of activities ntpd.  It's a little hyperactive beast.  The ratio is about 2 ½ pages long during only a short excerpt.  I can paste the report into this thread if it helps.

  But my real question is: is it normal that ntpd to be so active?  If this sounds abnormal, how can I get the little beast under control?

  In case it will help, here is the report of the sample of activity that the activity monitor took of ntpd.  Of course, it seems that he is busy, if all this has to do is sync with a network time service.

• NTP synchronization drop Linux Compact RIO

  Hello

  I followed this method of synchronization with NTP (https://decibel.ni.com/content/docs/DOC-39178) and it works most of the time, but sometimes, I lost the NTP synchronization and crio are about 7 s forward. (I get the problem with a 9035 and a 9068).

  When synchronization is no longer works, Pei ntpq command responds "connection refused".

  Does anyone have an idea about the problem?

  Thank you

  Hello Jacques,.

  Sorry, I wasn't very clear

  Before you add the ntp-utils, I lost the synchronization several times: sometimes after a few days, once, after more than 2 weeks, but also sometimes on startup, I was not able to sync

  Given that I have install ntp utils, 10 days earlier, on 5 compact rio, I run the of-p command ntpq every minute and I always get a response, then that means I never lost the NTP synchronization (or I lost it less than a minute). I will continue to monitor them, but it seems that ntp-utils has helped me as weel

• cRIO 9076 time sync

  If this is true NTP synchronization is a big correction of the date-time on the boot. After starting, it adjusts the processor clock to account for drift.  The algorithm has tolerance of error, but if you exceed this tolerance (i.e. If you're too far out of sync) it will stop trying to set the CPU clock to synchronize. Calling the Set Date & Time VI typically causes the clock to go beyond the tolerance of error algorithm. Is there a tolerance of error on the large correction also? I'm not able to get my system to sync on startup, so if the controller resets to zero, I'm wasting my time. Will there be a VI to query the server sntp in initialization and time setting here?

  If for some reason, I get to work with NIST but not on our servers. So, I am dealing with our network again. Thanks for the help.

• Clock of the Internet will not auto sync on my windows Tablet 7, operation of the manual synchronization. What causes this?

  My windows clock will not auto sync and I have to manually synchronize the clock. Tablets clock falls almost immediately after be synchronized and it does not automatically sync with time windows but a manual synchronization works very well.

  I even made a full recovery, thinking it was corrupt software or associated possible viruses, but the problem persists.

  Any ideas would be greatly appreciated.

  Hello

  Thank you for visiting Microsoft Community.

  That by description, you experience the problem with the internet clock won't auto sync but it will manually sync on Windows 7 tablet.

  I certainly understand your concern and appreciate very much all your efforts to try to solve this problem.

  In order to understand the issue more clearly, I would ask that kindly provide me with the following information.

  1. You did any specific changes before this problem?

  2. Do you receive an error message? If Yes, what is the exact error message and the error code?

  3. What is the make and model of the Windows 7 Tablet?

  4. Since how long you are having this problem?

  I suggest you to refer to the steps below and check if that helps.

  1. Right click on the clock in the taskbar and choose adjust date/time.
  2. The time tab-click Internet, and then press change settings.
  3. Delete what is in the server field and replace it with pool.ntp.org.
  4. Click Update now. In a few seconds, Windows clock must get synchronized.
  5. Click on OK and then OK again and you're done.

  For reference:

  You can also see the following article in Microsoft Help below and check if that helps.

  Set the clock

  Hello Chetan,

  Please check if these messages are displayed in the log journal see the:

  ntpd [30009]: ntp:time reset + 3.141701 s

  ntpd [30009]: ntp:time reset + 3.196390 s

  ntpd [30009]: ntp:time reset + 3.161593 s

  ntpd [30009]: ntp:time reset + 3.269245 s

  This means that you have reached bug CSCsv11236.  Sysclk freq is 1333.330000 MHz, which should be 1328,1275 MHz. I'll spare you the math, but it works at about 3.15 seconds per 15 minutes + fresh General ntp.

  The solution is simple: make sure that you are running

  BIOS: version 1.0.19

  Kickstart: version 5.0 (4)

  system: version 5.0 (4)

  and powercycle the entire system.  This should reset the clock to the correct processor speed.  This can take a few days for NTP to stabilize again.

• (S) synchronization NTP on SG300 access switches?

  Hello

  In our network, two domain controllers are configured as central (S) NTP servers. Mode Layer 3 it is quit easy to sync with these (S) NTP servers. But what is actually the best approach for access switches mode layer 2, which are connected to the layer 3 switch? The only IP address, they are part of the management VLAN ID 1, which is not routable. I actually need something like a show without having to put a NTP server in management vLAN.

  Boudewijn

  Is your switch to level 3 of the entry door for your VLAN? VLAN 1 can be routed, the only restriction to this would be if you don't have no roads to vlan1. If your NTP server and Layer 2 switch points their default gateway to your layer 3, level 3 switch switch can route traffic across this way.

  It really depends on how you have the network configuration and what device manages routing for you on the local network.

  Hello

  The output of the show ntp peer-status seems correct and the * indicates at this time there is sync was from the 10.1.32.4 server.

  The Show ntp status command is for a different purpose. According to the command reference the 'indicates if Cisco Fabric Services (CFS) is enabled or disabled for the purposes of NTP and know if a fabric lock is in place, because a configuration is in progress'. NTP distribution is discussed in the Distribution of NTP CFS of the configuration guide.

• Cisco ISE synchronization and NTP server

  I am currently implementing Cisco ISE to our customer.

  But having a little problem Cisco ISE cannot synchronize with NTP server.

  Keep in mind, NTP servers in AD.

  Currently, Cisco ISE synchronize just at the local level.

  Cisco ISE implemented distributed mode, when there are two Cisco ISE installed on VMware (Administration & monitoring primary & secondary node), and another is the device (political Service node).

  As a result of it might not sync server NTP and the ISE of Cisco, Cisco ISE often OUT-OF-SYN.

  Is there a solution for this problem?

  Gandhi,

  This is a known issue, I have crossed upwards and have not read that you use AD as your NTP server, there have been problems with integration of the ISE and ACS with AD as their ntp source, please use another device like sources ntp, for example a router.

  Thank you

  PRVF-5416: failure of the request of the NTP daemon on all nodes

  Control of clock synchronization using time Protocol (NTP) network failed

  
  We found a document of MOS suggesting to manually day /etc/ntp.conf and restart the ntp daemon - but it is not clear whether the services running the grid needs to stop. Can you please help

  Thank you

  No, we don't need to reboot.

  The time is out of sync currently?

  Thank you
