SNMP overview

SNMP is a set of protocols for managing complex networks. SNMP sends messages, called protocol data units (PDUs), to different parts of a network. SNMP-compliant devices, called agents, store data about themselves in Management Information Bases (MIBs) and return this data to the SNMP requesters.

The Brocade ICX 6650 Switch Security Configuration Guide introduces a few methods used to secure SNMP access. This chapter presents additional methods for securing SNMP access to Brocade devices. It contains the following sections:

“SNMP community strings”

“User-based security model”

“SNMP v3 configuration examples”
