Cisco ASR 9000 Series User Manual

In this illustration, the agent sends a trap to the manager, but the trap does not reach the manager. Because
the agent has no way of knowing that the trap did not reach its destination, the trap is not sent again. The
manager never receives the trap.

How to Implement SNMP on Cisco IOS XR Software
This section describes how to implement SNMP.
The snmp-server commands enable SNMP on Management Ethernet interfaces by default. For information
on how to enable SNMP server support on other inband interfaces, see the Implementing Management Plane
Protection on Cisco IOS XR Software module in Cisco ASR 9000 Series Aggregation Services Router System
Security Configuration Guide.
Configuring SNMPv3
This task explains how to configure SNMPv3 for network management and monitoring.
No specific command enables SNMPv3; the first snmp-server global configuration command (config),
that you issue enables SNMPv3. Therefore, the sequence in which you issue the snmp-server commands
for this task does not matter.
