    My Core switch 8212zl, I found,

    time change automatically to year 90.

    I 01/03/90 09:29:28 02631 SNTP: AM2: Server not found at 1.1.1.1.
    I 01/03/90 09:29:28 00414 SNTP: AM2: Unable to reach configured SNTP servers

    I check the  server already running and also ping.

    How to fix?

    There is no NTP server at 1.1.1.1; configure a proper IP address for your NTP server.

    I know 1.1  it's an example.

    192.168.x.x is my ntp.

    What is the reason behind spending energy to obfuscate (not even to hide!) a very common private IP address instead of using the same amount of energy - and saving few unfruitful posts about clarifying "who is who" - to provide important details that can be used to help you immediately? That's a mistery.

    Is the server 192.168.10.10 configured for SNTP? It seems it is not responding.

    If you are sure the server is an NTP server, and operational, I would run a packet capture to see where the NTP traffic is lost; most times that is easiest on the NTP server...

    Can you more elaborate regarding packet-capture?

    You can use a tool like Wireshark or tcpdump to capture network traffic; and analyze it. If you don't know how to do it, it may be wise to find someone who can, like a colleague or your Aruba partner, or Aruba support.
