HP JG221A User Manual

• Trap—The SNMP agent sends traps to report events to the NMS.
• Inform—The NMS sends alarms to other NMSs.
SNMP protocol versions
HP supports SNMPv1, SNMPv2c, and SNMPv3.
• SNMPv1 uses community names for authentication. To access an SNMP agent, an NMS must use
the same community name as set on the SNMP agent. If the community name used by the NMS is
different from the community name set on the agent, the NMS cannot establish an SNMP session to
access the agent or receive traps and notifications from the agent.
• SNMPv2c also uses community names for authentication. SNMPv2c is compatible with SNMPv1,
but supports more operation modes, data types, and error codes.
• SNMPv3 uses a user-based security model (USM) to secure SNMP communication. You can
configure authentication and privacy mechanisms to authenticate and encrypt SNMP packets for
integrity, authenticity, and confidentiality.
IMPORTANT:
An NMS and an SNMP agent must use the same SNMP version to communicate with each other.
