This protocol promotes interoperability because SNMP-capable systems must adhere to a common set of framework and language rules. Understanding the components of SNMP makes it possible to use third-party tools to view, browse, and manipulate Brocade switch variables (MIBs) remotely as well as to set up an enterprise-level management process. Every Brocade switch and director supports SNMP. Recipients for SNMP traps are restricted according to security levels. Security levels are selected and set for a switch using the snmpconfig --set seclevel command. To select and set SNMP security levels, issue the command snmpconfig --set seclevel after having logged in to the switch as admin. The following example sets the SNMP security level to 1 (authentication only). This setting allows all SNMPv1 users to perform GET and SET operations on MIBs, but creates an exception for SNMPv3 users that do not have authentication and privacy privileges (noAuthnoPriv). switch:admin> snmpconfig --set seclevel Select SNMP Security Level (0 = No security, 1 = Authentication only, 2 = Authentication and Privacy, 3 = sxNo Access): (0..3) [0] Select SNMP SET Security Level (0 = No security, 1 = Authentication only, 2 = Authentication and Privacy, 3 = No Access): (0..3) [0] TABLE 1 Security level options Security level Protocol No security [0] (noAuthnoPriv) Authentication only [1] (authNoPriv) SNMPv1 SNMPv3 SNMPv1 SNMPv3 Query behavior Allowed.
