When we use Huawei NE series routers, we sometimes encounter problems. How can these problems be solved? We provide the Troubleshooting Guide to help you.
If you encounter the Clock Is Not Synchronized, perform the following steps:
1. Check the NTP status.
<HUAWEI> display ntp-service status
clock status: unsynchronized
clock stratum: 16
reference clock ID: none
nominal frequency: 100.0000 Hz
actual frequency: 99.9995 Hz
clock precision: 2^18
clock offset: 0.0000 ms
root delay: 0.00 ms
root dispersion: 0.00 ms
peer dispersion: 0.00 ms
reference time: 14:25:55.477 UTC Jun 9 2010(CFBA22F3.7A4B76F6)
The "clock status" field is displayed as "unsynchronized", indicating that the local system clock is not synchronized with any NTP server or a reference clock.
2. Check the status of the NTP connection.
<HUAWEI> display ntp-service sessions
clock source: 10.1.1.1
clock stratum: 8
clock status: configured, master, sane, valid
reference clock ID: LOCAL(0)
reach: 255
current poll: 1024
now: 355
offset: 0.5995 ms
delay: 3.01 ms
disper: 25.42 ms
3. Run the ping command on the NTP client to check the status of the link to the NTP server.
[~HUAWEI] ping 10.2.14.1
PING 10.2.14.1: 56 data bytes, press CTRL_C to break

--- 10.2.14.1 ping statistics ---
5 packet(s) transmitted
0 packet(s) received
100.00% packet loss
§ The displayed information "100.00% packetloss" indicates that the link is faulty.
§ If the packet loss percentage is not 100.00%, it indicates that the link flaps.
§ If the packet loss percentage is 0.00%, it indicates that the link is normal. You need to contact Huawei technical support personnel to check whether packets can be sent and received normally.
4. If the fault persists, collect the following information and contact technical support personnel.
§ Results of the preceding troubleshooting procedures
§ Configuration files, log files, and alarm files of the devices
