Using the SNMP Protocol

Using the SNMP Protocol

The security of different Simple Network Management Protocol (SNMP) versions varies. Using more secure versions is recommended.

The FusionStorage supports the following SNMP versions:

  • V1: The SNMPv1 is the first release of the SNMP protocol version, uses the community name authentication method. The security of SNMPv1 is poor and the return message of the error code is also less, is no longer in use.
  • V2C: The SNMPv2c uses the community name authentication method and it expands this function of the SNMPv1. It supports more types of operations and data and provides rich error codes to distinguish errors subtly.
  • V3: The SNMPv3 uses the user security mode-based authentication. You can set the authentication and encryption functions. The authentication function verifies the validity of the packet sender, preventing accesses of unauthenticated users. The encryption function encrypts the packets transmitted between the NMS server and its managed devices, avoiding eavesdropping. The SNMPv3 improves the communication security by combining the authentication and encryption functions.

SNMPv1 and SNMPv2c are less secure. Security risks arise if the SNMP protocol version is set to V1 or V2C. You are advised to select the V3 SNMP protocol version.
