Prefer SNMPv3 over SNMPv2

It's recommended to use SNMP Version 3 (SNMPv3) instead of SNMPv1 and SNMPv2c, if possible. SNMPv3 provides secure access to the device using a combination of authentication (e.g., MD5, SHA-1 or SHA-2) and encryption (e.g., DES, 3DES, AES-128, AES-192, or AES-256) of packets over the network. It's also recommended that you periodically change the SNMPv3 authentication and privacy keys.

To configure SNMPv3 users:
1. Open the SNMPv3 Users table (Setup menu > Administration tab > SNMP folder > SNMP V3 Users).
2. Click New, and then configure an SNMPv3 user:
