Command Syntax and Usage

name <32 character name>

Defines the name of the group.

prefix <32 character name>

Defines the name of the context. An SNMP context is a collection of management information that an SNMP entity can access. An SNMP entity has access to many contexts. For more information on naming the management information, see RFC2571, the SNMP Architecture document. The view-based Access Control Model defines a table that lists the locally available contexts by con- textName.

model usmsnmpv1snmpv2

level noAuthNoPrivauthNoPrivauthPriv

Defines the minimum level of security required to gain access rights. The level noAuthNoPriv means that the SNMP message will be sent without authentication and without using a privacy pro- tocol. The level authNoPriv means that the SNMP message will be sent with authentication but without using a privacy protocol. The authPriv means that the SNMP message will be sent both with authentication and using a privacy protocol.
