Chapter Securing SNMP Access 40 Table 236 lists individual Dell PowerConnect switches and the SNMP access methods they support. These features are supported in the Layer 2, base Layer 3, edge Layer 3, and full Layer 3 software images, except where explicitly noted. TABLE 236 Supported SNMP access features Feature PowerConnect B-Series FCX SNMP v1, v2, v3 Yes Community strings Yes User-based security model for SNMP v3 Yes SNMP v3 traps Yes Defining the UDP port for SNMP v3 traps Yes SNMP v3 over IPv6 Yes AES encryption for SNMP v3 Yes 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. Chapter 32, "Securing Access to Management Functions" introduced a few methods used to secure SNMP access. They included the following: • "Using ACLs to restrict SNMP access" on page 1140 • "Restricting SNMP access to a specific IP address" on page 1142 • "Restricting SNMP access to a specific VLAN" on page 1145 • "Disabling SNMP access" on page 1149 This chapter presents additional methods for securing SNMP access to Dell PowerConnect devices. It contains the following sections: • "Establishing SNMP community strings" • "Using the user-based security model" • "SNMP v3 Configuration examples" • "SNMP version 3 traps" • "Displaying SNMP Information" • "SNMP v3 Configuration examples" PowerConnect B-Series FCX Configuration Guide 53-1002266-01 1365
