显示 SNMP
您可以在 Junos OS 操作模式下访问多个命令来监控 SNMP 信息。其中一些命令是：
show snmp health-monitor，其中显示运行状况监视器日志和警报信息。show snmp mib，显示来自 MIB 的信息，例如设备和系统信息。show snmp statistics，其中显示 SNMP 统计信息，例如数据包数、静默丢弃和无效输出值。show snmp rmon，其中显示 RMON 告警、事件、历史记录和日志信息
以下示例提供了命令 show snmp health-monitor 的示例输出：
user@switch> show snmp health-monitor
