Snmp Protocol Version; Snmp Configuration; Configuration Task List - HP V1910 User Manual

SNMP protocol version

SNMP agents support three SNMP protocol versions: SNMPv1, SNMPv2c, and SNMPv3.
SNMPv1 uses community names for authentication. A community name performs a similar role as a

password to regulate access from the NMS to the agent. If the community name provided by the NMS
is different from the community name set on the agent, the SNMP connection cannot be established
and the NMS fails to access the agent.
 SNMPv2c uses community names for authentication. SNMPv2c is compatible with SNMPv1, but it
provides more operation modes, supports more data types, and provides various error codes for
troubleshooting.
SNMPv3 offers authentication based on the User-based Security Model (USM), which allows network

administrators to set authentication and privacy functions. The authentication function is used to
authenticate the validity of the sending end of the authentication packets, preventing access of
unauthorized users. The privacy function is used to encrypt packets between the NMS and agents,
preventing the packets from being intercepted. USM ensures more secure communication between
NMSs and agents by providing authentication and privacy functions.
Successful interaction between an NMS and the agents requires consistency of SNMP versions configured
on them.

SNMP configuration

Configuration task list

As configurations for SNMPv3 differ substantially from those for SNMPv1 and SNMPv2c, their
configuration tasks are introduced separately as follows.
