Explanation

SNMPv3 (Simple Network Management Protocol version 3) is the only version of SNMP that provides both authentication and encryption (privacy) for management data. SNMPv1 and SNMPv2c transmit data including community strings in plaintext, making them vulnerable to eavesdropping. SNMPv3 supports USM (User-based Security Model) with MD5/SHA for authentication and DES/AES for encryption. VTP (VLAN Trunking Protocol) propagates VLAN configurations between Cisco switches. CDP (Cisco Discovery Protocol) discovers neighboring Cisco devices. IPSec is a tunneling/encryption protocol for IP traffic, not a device management protocol.
