Conguring the CPU Utilization for SNMP Traps
When the total CPU utilization exceeds the congured threshold for the specied time, a threshold notication is sent as an SNMP trap. If
a low threshold value is not specied, the low threshold value is set to the same value as the high threshold value. The system generates a
Syslog and SNMP trap each time the congured CPU threshold is crossed.
NOTE: The 5 sec util-threshold cpu command is disabled by default on all switches. To enable the command, enter the
util-threshold cpu 5sec all high { value greater than zero }. To disable the Syslog and traps for the 5 sec CPU
utilization thresholds, enter the
util-threshold cpu 5sec all high 0 or no util-threshold cpu 5sec {cp |
rp | lp slot-id | all} command.
Use the util-threshold cpu command to congure the high or low CPU utilization threshold for SNMP traps. Use the show util-
threshold cpu command to display the congured values of CPU utilization thresholds.
Parameters
• cpu-utilization-time — Enter one of the following values to congure the threshold level for the time in which a switch CPU can be
used:
– 5 sec
– 1 min
– 5 min
• cp — Enter the keyword cp to congure the CPU utilization time for the Control Processor CPU.
• rp — Enter the keyword rp to congure the CPU utilization time for the Route Processor CPU
• lp — Enter the keyword lp to congure the line processor CPU utilization time. The range of switch slot IDs is from 0 to 2.
• pe — Congure the CPU utilization time of all PEs that are congured in the system.
• all — Enter the keyword all to congure the CPU utilization time on all switch CPUs: Control Processor, Route Processor, PE, and line
cards.
• {{high | low} cpu-utilization-threshold-percentage} — Enter a percentage value to congure the high or low threshold level for the time
in which a switch CPU can be used. The percentage of CPU use ranges from 0 to 100.
Defaults
– High CPU utilization threshold: 1 min = 85%, 5 min = 80%
– Low CPU utilization threshold: 1 min = 75%, 5 min = 70%
NOTE
: A threshold level of 0 disables Syslog and SNMP traps.
• Congure the high or low CPU utilization threshold for SNMP traps.
