    Field Details
    Credential name Provide a name to the SNMP Credential.
    SNMP Version
    Specify the SNMP version that is associated with this SNMP configuration. Make sure to select the version that is supported on the device. SNMP versions are as follows:
    • V1

      Basic version of SNMP. This version is supported by most devices and simple to set up. It has limited security.

    • V2

      Supports 64-bit counters to monitor the bandwidth usage of networks high volumes of data. It has limited security.

    • V3
