Utility MIB Examples
This topic presents examples of show command output
and SNMP MIB walk results using the utility MIB for power readings
on a Junos OS device.
Show Command Output for Power Readings
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
In the following example, the index is PEM pem number type of reading.
