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
System Security Configuration Guide for Cisco NCS 5000
Series Routers
.
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.
