Snmp Protocol Operations; Snmp Versions - Alcatel-Lucent 7210 SAS E OS System Management Manual

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:

SNMP Versions

The agent supports multiple versions of the SNMP protocol.
7210 SAS-E OS System Management Guide
• 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 Version 1 (SNMPv1) is the original Internet-standard network management
framework.
SNMPv1 uses a community string match for authentication.
• The 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.
