Monitoring Power Consumption
You can monitor the power consumption of the switch and PDs by
configuring the unit to transmit an SNMP power-inline trap if their
combined power requirements exceed a defined threshold. The threshold
is specified as a percentage of the switch’s nominal power, which is the
total available power of the switch. You can view the nominal power with
“SHOW POWER-INLINE” on page 288. The threshold has the range of 1
to 99%. You may specify only one threshold. The commands for setting
the threshold and activating the trap are listed in Table 21.
Note
You have to configure SNMP to use the trap. For instructions, refer
to Chapter 73, “SNMPv1 and SNMPv2c” on page 1143 or Chapter
75, “SNMPv3 Commands” on page 1179.
This example configures the switch to send the SNMP power-inline trap if
the power requirements of the switch and PDs exceed 90% of its nominal
power:
awplus> enable
awplus# configure terminal
awplus(config)# power-inline usage-threshold 90
awplus(config)# snmp-server
awplus(config)# snmp-server enable trap power-inline
