Maintenance module, assembling the commonly used system tools to manage the switch,
provides the convenient method to locate and solve the network problem.
1. System Monitor: Monitor the utilization status of the memory and the CPU of switch.
2. Log: View the configuration parameters of the switch and find out the errors via the Logs.
3. Cable Test: Test the connection status of the cable to locate and diagnose the trouble
spot of the network.
4. Network Diagnostics: Test whether the destination device is reachable and detect the
route hops from the switch to the destination device.
5. DLDP: Monitor the physical configuration of the cables and detect whether a unidirectional
link exists.
15.1 System Monitor
System Monitor functions to display the utilization status of the memory and the CPU of switch
via the data graph. The CPU utilization rate and the memory utilization rate should fluctuate
stably around a specific value. If the CPU utilization rate or the memory utilization rate increases
markedly, please detect whether the network is being attacked.
The System Monitor function is implemented on the CPU Monitor and Memory Monitor
pages.
