Upgraded this weekend from 12.2(33)SXI5 to SXJ2. Everything appears fine accept NTP. I understand that SJ2 upgrades NTP from v3 to v4, but although it appears to be working, the local clock never slews (corrects to NTP time). The offsets in ntp stay stable, rather than converging on the correct time.
Anyone else seen this? switch-core1#show ntp associations address ref clock st when poll reach delay offset disp +~128.4.1.1 .PPS. 1 431 512 377 6.220 186.249 9.071 ~127.127.1.1 .LOCL. 7 4 16 377 0.000 0.000 0.238 +~209.81.9.7 .GPS. 1 420 512 377 76.374 189.382 13.435 +~69.36.224.15 .GPS. 1 179 512 377 80.046 188.355 17.814 -~64.183.55.54 109.99.226.215 3 421 512 377 84.159 175.329 9.469 -~204.152.184.72 .GPS. 1 427 512 377 74.559 185.210 12.907 +~216.218.254.202 .CDMA. 1 400 512 377 75.982 189.300 11.174 -~18.26.4.105 .CDMA. 1 406 512 377 36.859 173.421 14.156 *~209.51.161.238 .CDMA. 1 436 512 377 4.063 188.962 11.768 -~130.207.244.240 .GPS. 1 412 512 377 28.666 184.413 10.079 +~198.60.22.240 .GPS. 1 349 512 377 64.370 187.676 14.138 * sys.peer, # selected, + candidate, - outlyer, x falseticker, ~ configured switch-core1#show ntp status Clock is synchronized, stratum 2, reference is 209.51.161.238 nominal freq is 250.0000 Hz, actual freq is 249.9999 Hz, precision is 2**24 reference time is D2B44C27.24A08416 (12:08:55.143 EST Sun Jan 8 2012) clock offset is 188.9620 msec, root delay is 4.06 msec root dispersion is 215.24 msec, peer dispersion is 11.76 msec loopfilter state is 'CTRL' (Normal Controlled Loop), drift is 0.000000180 s/s system poll interval is 512, last update was 1219 sec ago. switch-core1#show clock detail 12:29:18.402 EST Sun Jan 8 2012 Time source is NTP Summer time starts 02:00:00 EST Sun Mar 11 2012 Summer time ends 02:00:00 EDT Sun Nov 4 2012 ---- Matthew Huff | 1 Manhattanville Rd Director of Operations | Purchase, NY 10577 OTA Management LLC | Phone: 914-460-4039 aim: matthewbhuff | Fax: 914-460-4139 _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
