https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/snmp/configuration/xe-16/snmp-xe-16-book/nm-snmp-encrypt-snmp-support.htmlThe version of SNMP used for providing encryption for SNMP management traffic in collaboration deployments is SNMPv3.
SNMP (Simple Network Management Protocol) is a protocol used to manage and monitor network devices. It allows network administrators to manage network performance, find and solve network problems, and plan for network growth.
SNMPv3 is the most secure version of SNMP. It provides both authentication and encryption of SNMP messages to protect them from unauthorized access or modification. SNMPv3 uses the HMAC (Hash-based Message Authentication Code) algorithm to ensure message integrity and authenticity, and the encryption algorithm, such as AES (Advanced Encryption Standard), to encrypt SNMP messages.
In contrast, SNMPv1 and SNMPv2c do not provide any encryption for SNMP messages. SNMPv1 uses a simple community string-based authentication mechanism, which is insecure and easily compromised. SNMPv2c provides improved features over SNMPv1 but still lacks strong security features such as encryption.
Therefore, in order to provide secure SNMP management traffic in collaboration deployments, it is recommended to use SNMPv3 with proper authentication and encryption mechanisms.
