Setting the SNMP security level

The Simple Network Management Protocol (SNMP) is an industry-standard method of monitoring

and managing network devices. 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]
