NetWorker Administration Guide中提供了有关配置 SNMPV3 陷阱的说明。  这应该与知识库文章一起用于初始配置：如何配置 NetWorker 以使用 SNMP。

以下文章提供了 Linux 操作系统上的配置文件的工作示例。

下面是提供给客户的示例配置，使无法正常工作的 SNMPV3 陷阱环境能够成功工作。

/etc/snmp/snmpd.conf 
# Please see /usr/share/doc/packages/net-snmp/EXAMPLE.conf for a
# more complete example and snmpd.conf(5).
#
# Writing is disabled by default for security reasons.  If you'd like
# to enable it uncomment the rwcommunity line and change the community
# name to something nominally secure (keeping in mind that this is
# transmitted in clear text).

# don't use ' < > in strings for syslocation or syscontact
# Note that if you define the following here you won't be able to change
# them with snmpset
# syslocation Server Room
# syscontact Sysadmin (root@localhost)

# These really aren't meant for production use.  They include all MIBS
# and can use considerable resources.  See snmpd.conf(5) for information
# on setting up groups and limiting MIBS.
rocommunity public 127.0.0.1

# sec.name source community
traptest snmpv3_user 192.168.xxx.xxx/24 public

# sec.model sec.name
group incremental usm snmpv3_user
rouser traptest

提醒：对配置文件的任何更改都需要重新启动 snmpd 和 snmptrapd。
 

测试

在陷阱接收器主机（也可以是 NetWorker 服务器）上启动 putty 会话并运行： 
snmptrapd -f -C -c /etc/snmp/snmptrapd.conf -Le -M /usr/share/snmp/mibs -m NETWORKER-MIB
*注意：为 Debug 输出

添加 -D 开关 从 NetWorker 服务器启动第二个 putty 会话并运行： 
nsrtrap -i 3 -v trapreceiver_hostname
This is a V3 Test
ctrl <D>
如果成功，您应该在第一次 putty 会话的日志中看到; 
2024-03-01 13:10:45 nwserv1 [UDP: [192.168.xxx.xxx]:33276->[192.168.xx.xxx]:162]:
SNMPv2-SMI::mib-2.1.3.0 = Timeticks: (7254049) 20:09:00.49      SNMPv2-SMI::snmpModules.1.1.4.1.0 = OID: NETWORKER-MIB::nwServerNotification    SNMPv2-SMI::mib-2.1.1.0 = STRING: "This is a V3 Test"


配置备份通知：

在 SNMP 陷阱服务器上，运行以下命令：

snmptrapd -f -C -c /etc/snmp/snmptrapd.conf -Le -M /usr/share/snmp/mibs -m NETWORKER-MIB &

注意;

  • 操作级别的备份配置仅支持 SNMPv2
  • 策略级别的备份配置同时支持 SNMPv2 和 v3
/usr/sbin/nsrtrap trapreceiver_hostname -i 3
