Chapter 7: Using SNMP

SNMP Sets and Thresholds
Some objects can be configured from the SNMP manager using SNMP
set commands. Objects that can be configured have a MAX-ACCESS
level of "read-write" in the MIB.
These objects include threshold objects, which causes the PX to
generate a warning and send an SNMP notification when certain
parameters are exceeded. See
Setting Power Thresholds
(on page
215) for a description of how thresholds work.
Note: When configuring the thresholds via SNMP set commands, ensure
the value of upper critical threshold is higher than that of upper warning
threshold.
Configuring NTP Server Settings
Using SNMP, you can change the following NTP server-related settings:
 Enable or disable synchronizing the PDU's date and time with NTP
servers.
 Enable or disable the use of DHCP-assigned NTP servers if
synchronization with NTP servers is enabled.
 Manually assign the primary NTP server if the use of
DHCP-assigned NTP servers is disabled.
 Manually assign the secondary NTP server (optional).
Tip: To specify the time zone, use the CLI or web interface instead. For
the CLI, see
Setting the Time Zone (on page 414). For the web
interface, see Setting the Date and Time (on page 134).
When using the SNMP SET command to specify or change NTP servers,
it is required that both the NTP server's address type and address be set
in the command line simultaneously.
For example, the SNMP command to change the primary NTP server's
address from IPv4 (192.168.84.84) to host name looks similar to the
following:
snmpset -v2c -c private 192.168.84.84
firstNTPServerAddressType = dns firstNTPServerAddress =
"angu.pep.com"
Retrieving Energy Usage
You can discover how much energy an IT device consumes by retrieving
the Active Energy for the outlet this IT device is plugged into. The Active
Energy values are included in the outletSensorMeasurementsTable,
along with other outlet sensor readings.
