![]() ![]() ![]() NTP is a finicky protocol to be sure, but I'd take a closer look at your NTP master. Note the reasonable stratum from my NTP master (simple config on the master router was "ntp master 5") I labbed this out with two routers to make sure how the format should look like from the NTP master.Mar 1 00:55:51.533: NTP: rcv packet from 10.0.0.8 to 10.0.0.30 on Serial0/0: So your NTP server is declaring it is stratum 0 - that's not going to work. This debug line makes me curious about the validity of your NTP master: 1d03h: NTP: rcv packet from 10.0.0.8 to 10.0.0.30 on Vlan20: I know under show ntp associations detail if insane or invalid or stratum 16 is in there the cisco switch won't sync time. I'm not really sure whwere to go to from here. Our mode active, peer mode active, our poll intvl 512, peer poll intvl 256 Here is show ntp associatsions detail: 10.0.0.8 configured, insane, invalid, stratum 16 * master (synced), # master (unsynced), + selected, - candidate, ~ configured Here is show ntp associations: address ref clock st when poll reach delay offset disp ![]() Root dispersion is 0.00 msec, peer dispersion is 0.00 msec Nominal freq is 119.2092 Hz, actual freq is 119.2092 Hz, precision is 2**17 Here is show ntp status Clock is unsynchronized, stratum 16, no reference clock ![]() Here is running-config ntp server 10.0.0.8 First I thought it was due to a bug I was reading about regarding Win32Timeservice, or something like that, however I confirmed that this is a NTPD server (10.0.0.8) running on Unix. I've tried setting the clock close to the UTC time, but i still don't show time synced. I am trying to configure a cisco switch as a ntp client, however I cannot get past the show ntp status of Clock is unsynchronized, stratum 16, no reference clock. ![]()
