15.5.3 Enable SNMP Service
The console server supports different versions of SNMP including SNMPv1, SNMPv2c and SNMPv3.
SNMP, although an industry standard, brings with it a variety of security concerns. For example, SNMPv1 and SNMPv2c
offer no inherent privacy, while SNMPv3 is susceptible to man-in-the-middle attacks. Recent IETF developments
suggests tunnelling SNMP over widely accepted technologies such as SSH (Secure Shell) or TLS (Transport Layer
Security) rather than relying on a less mature security systems such as SNMPv3's USM (User-based Security Model).
