SNMP
7950 SR OS System Management Guide Page 247
The SNMP agent provides management information to support a collection of IETF specified
MIBs and a number of MIBs defined to manage device parameters and network data unique to
Alcatel-Lucent’s router.
SNMP Protocol Operations
Between the SNMP agent and the SNMP manager the following actions can occur:
• The manager can get information from the agent.
• The manager can set the value of a MIB object that is controlled by an agent.
• The agent notifies the manager of significant events that occur on the router.
SNMP Versions
The agent supports multiple versions of the SNMP protocol.
• SNMP Version 1 (SNMPv1) is the original Internet-standard network management
framework.
SNMPv1 uses a community string match for authentication.
• The OS implementation uses SNMPv2c, the community-based administrative
framework for SNMPv2. SNMPv2c uses a community string match for
authentication.
• In SNMP Version 3 (SNMPv3), USM defines the user authentication and encryption
features. View Access Control MIB (VACM) defines the user access control features.
The SNMP-COMMUNITY-MIB is used to associate SNMPv1/SNMPv2c community
strings with SNMPv3 VACM access control.
SNMPv3 uses a username match for authentication.
