验证是否已启用 SNMP
使用命令行界面（CLI）可以验证集群上是否已启用 SNMP。
在 ONTAP 9.4 或更高版本中，默认情况下在集群级别启用 SNMPv3，在默认情况下禁用 SNMPv1 和 SNMPv2c。创建 SNMP 团体时，将启用 SNMPv1 和 SNMPv2c。
默认情况下，数据 LIF 上禁用 SNMP。有关对数据 LIF 启用 SNMP 的信息，请参阅网络文档。
过程
- 检查 SNMP 状态。
- 执行以下命令检查是否已启用 SNMP：
options - 在以下示例中，检查 DM 系列集群设置中

- 执行以下命令检查是否已启用 SNMP：
- 启用/禁用 SNMP。
- 使用以上命令检查集群的当前 SNMP 状态。如果未启用 SNMP，请启用。可运行 options snmp.enable {on|off} 命令从命令行界面启用或禁用 SNMP。
on：启用 SNMP
off：禁用 SNMP
- 运行以下命令在 DM 系列集群设置中启用 SNMP。
Cluster-1::> options -option-name snmp.enable -option-value on
