Ntp not updating cisco
For example, Eastern Standard Time (EST) can be expressed as UTC - (five hours behind UTC).
Note that UTC is not equivalent to GMT, which is a time zone in its own right with a UTC offset of .
We can see what a router believes is the current time and date with the command Router# clock set 27 march 2011 Router# *Mar 27 .000: %SYS-6-CLOCKUPDATE: System clock has been updated from UTC Sun Mar 27 2011 to UTC Sun Mar 27 2011, configured from console by console.
I have 3 2650XM routers that i cannot get to sync to a NTP server.cisco of course wanted me to upgrade the IOS.Large organizations (particularly governments and militaries) maintain their own stratum 0 and 1 NTP servers. For a protocol so obsessed with correct time, NTP certainly is slow: it can take upwards of five minutes to synchronize with an upstream server. Eventually, you'll see an association formed with at least one server, indicated by an asterisk. 1 24 64 77 0.000 36.610 189.06 * sys.peer, # selected, candidate, - outlyer, x falseticker, ~ configured nominal freq is 250.0000 Hz, actual freq is 249.9998 Hz, precision is 2**32 reference time is D13A115F. Only if I configure UTC 2 it's shows the right time. I set my LAN switches to synch to the local WAN router which synchs to our core router which synchs to our IAS/RADIUS server which synchs to a nearby NIST server. The hardest part was getting NTP going on the Windoze 2003 R2 server.For others, there are a number of public NTP servers available. The other server in this example, marked with a , has been designated a candidate (alternate). B0488F52 (.688 EDT Sun Mar 27 2011) clock offset is 0.0366 msec, root delay is 0.01 msec root dispersion is 0.23 msec, peer dispersion is 0.00 msec loopfilter state is 'CTRL' (Normal Controlled Loop), drift is 0.000000526 s/s system poll interval is 64, last update was 187 sec ago. I ended up using Meinberg NTP service which was easy to install and configure.Cheers and good luck Hello there, the command is in global config mode (config t): clock For the client router to be able to update it's clock from ntp master/server has to have it's own clock up and running before being able to syn it to the ntp server.More info about clock and ntp clock-period at: tecnikall,ive tried all of those commands all ready.
