实用程序 MIB 示例
本主题介绍使用实用程序 MIB 在 Junos OS 设备上读取电源的命令输出和 SNMP MIB 遍历结果的示例 show 。
显示功率读数的命令输出
user@host> show chassis environment pem
PEM 0 status:
State Online
Temperature OK
AC Input: OK
DC Output Voltage Current Power Load
50 12 600 35
PEM 1 status:
State Online
Temperature OK
AC Input: OK
DC Output Voltage Current Power Load
50 13 650 38
PEM 2 status:
State Present
PEM 3 status:
State Present
在以下示例中，索引为 PEM pem number type of reading。
填充了功率读数的 jnx 实用程序 MIB 的 SNMP MIB 行走结果
user@host> show snmp mib walk jnxUtil ascii
jnxUtilStringValue."PEM0dc-current" = 12
jnxUtilStringValue."PEM0dc-load" = 35
jnxUtilStringValue."PEM0dc-power" = 600
jnxUtilStringValue."PEM0dc-voltage" = 50
jnxUtilStringValue."PEM1dc-current" = 13
jnxUtilStringValue."PEM1dc-load" = 38
jnxUtilStringValue."PEM1dc-power" = 650
jnxUtilStringValue."PEM1dc-voltage" = 50
jnxUtilStringTime."PEM0dc-current" = 07 d9 09 15 0a 10 2d 00 2b 00 00
jnxUtilStringTime."PEM0dc-load" = 07 d9 09 15 0a 10 2d 00 2b 00 00
jnxUtilStringTime."PEM0dc-power" = 07 d9 09 15 0a 10 2d 00 2b 00 00
jnxUtilStringTime."PEM0dc-voltage" = 07 d9 09 15 0a 10 2d 00 2b 00 00
jnxUtilStringTime."PEM1dc-current" = 07 d9 09 15 0a 10 2d 00 2b 00 00
jnxUtilStringTime."PEM1dc-load" = 07 d9 09 15 0a 10 2d 00 2b 00 00
jnxUtilStringTime."PEM1dc-power" = 07 d9 09 15 0a 10 2d 00 2b 00 00
jnxUtilStringTime."PEM1dc-voltage" = 07 d9 09 15 0a 10 2d 00 2b 00 00
