• Notifications—Includes traps and informs. SNMP agent sends traps or informs to report events to
the NMS. The difference between these two types of notification is that informs require
acknowledgement but traps do not. The device supports only traps.
SNMP protocol versions
H3C supports SNMPv1, SNMPv2c, and SNMPv3. An NMS and an SNMP agent must use the same
SNMP version to communicate with each other.
• 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.
Configuring basic SNMP settings
SNMPv3 differs from SNMPv1 and SNMPv2c in many ways. Their configuration procedures are
described in separate sections.
Configuring basic SNMPv3 settings
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable the SNMP agent. snmp-agent
Optional.
By default, the SNMP agent is
disabled.
You can also enable the SNMP
agent by using any command that
begins with snmp-agent except the
snmp-agent calculate-password
command.
3. Configure system information
for the SNMP agent.
snmp-agent sys-info { contact
sys-contact | location sys-location
| version { all | { v1 | v2c |
v3 }* } }
Optional.
By default, the contact is Hangzhou
H3C Tech. Co.,Ltd., the physical
location is Hangzhou, China, and
