Impact on the System

The MM910 system time may be incorrect.

Possible Causes

  • The communication with the NTP server fails.
  • The minimum or maximum poll interval is too long.


  1. On the CLI of the active MM910, run the ntpq command and check whether the value of reach is 0.

    • If yes, go to 2.
    • If no, go go 3.

  2. Configure the network again, ensure that the NTP server is reachable, then go to 5.
  3. On HMM Web, choose System Management > System Settings > Timezone & NTP and check whether the poll internals are too long. You are advised to use the default minimum poll interval 4 (00 : 00 : 16) and the default maximum poll interval 6 (00 : 01 : 04).

    • If yes, go to 4.
    • If no, go go 5.

  4. Reset the poll internals to proper value.
  5. Half an hour later, check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go go 6.

  1. On the HMM WebUI, choose System Management > Information Collection, and collect logs.
  2. Contact Huawei technical support.
