Introduction 3Com Switch 7750 Ethernet switches are layer-2/layer-3 Ethernet switches with
multiple slots and of high reliability. CPUs of 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 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 Ethernet switches also support configuration of the CPU usage
threshold of the specified module. You can specify slot slot-number to configure
the CPU usage threshold for the specified module. When the CPU usage of the
module 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 modules and the specified module, the
CPU threshold of the specified module is determined by the latter one. For
example, if you set the CPU usage threshold of all the modules to 88 and set that
of the module in slot 2 to 77, the CPU usage threshold of the module in slot 2 is
77.
