    Description

    A service configuration includes configuring both the Network Time Protocol (NTP) and the Simple Network
    Management Protocol (SNMP) service settings.


    NTP(Network Time Protocol) is a protocol used to synchronize computer clock times within a network of computers. NTP uses Coordinated Universal Time (UTC) to synchronize computer clock times to a millisecond, and sometimes, to a fraction of a millisecond.

    SNMP (Simple Network Management Protocol) is a network protocol used over User Datagram Protocol (UDP)
    that allows you to monitor the status of the SonicWALL security appliance and receive notification of
    critical events as they occur on the network. SonicWALL security appliance supports SNMP v1/v2c/v3
    and all relevant Management Information Base II (MIBII) groups except egp and at.

    This article describes how to configure NTP and SNMP services on the SonicWALL firewall.
