Usage Threshold
Introduction 3Com Switch 7750 Family Ethernet switches are layer-2/layer-3 Ethernet switches
with multiple slots and of high reliability. CPUs of Switch Fabrics and I/O Modules
can process data. In actual networking, they may receive many requests for
data/packet processing at the same time due to large traffic or complicated
networking. These requests occupy many CPU resources and affect network
stability.
Switch 7750 Family Ethernet switches support CPU usage threshold configuration.
When the CPU usage exceeds the configured threshold, the switch sends trap
messages and log messages, according to which the network administrator can
modify the switch configuration.
Switch 7750 Family Ethernet switches also support configuration of the CPU
usage threshold of the specified board. You can specify slot slot-number to
configure the CPU usage threshold for the specified board. When the CPU usage
of the board in the specified slot exceeds the configured threshold, the switch
sends trap messages and log messages to the network administrator.
If you set CPU thresholds for both all the boards and the specified board, the CPU
threshold of the specified board is determined by the latter one. For example, if
you set the CPU usage threshold of all the boards to 88 and set that of the board
in slot 2 to 77, the CPU usage threshold of the board in slot 2 is 77.
