For S series switches except S1700 switches, you can run commands to display CPU and memory usage. - display cpu-usage [ slave | slot slot-id ]: displays CPU usage statistics. - display cpu-usage configuration [ slave | slot slot-id ]: displays CPU usage configuration. - display memory-usage [ slave | slot slot-id ]: displays memory usage statistics. - display memory-usage threshold [ slot slot-id ]: displays the alarm threshold for memory usage. For S series switches and E series switches except S1700 switches, you can check CPU and memory usage through the related MIB OIDs. - hwEntityCpuUsage 1.3.6.1.4.1.2011.5.25.31.1.1.1.1.5: provides CPU usage. - hwEntityCpuUsageThreshold 1.3.6.1.4.1.2011.5.25.31.1.1.1.1.6: provides the alarm threshold for CPU usage. - hwEntityMemUsage 1.3.6.1.4.1.2011.5.25.31.1.1.1.1.7: provides memory usage. - hwEntityMemUsageThreshold 1.3.6.1.4.1.2011.5.25.31.1.1.1.1.8: provides the alarm threshold for memory usage.

How to determine whether CPU usages of the system and processes are high for S series switches
For S series switches (except the S1700), the system CPU usage is within a normal range when the following conditions are met: - The CPU usage does not exceed 80% when the system runs for a long period. - The CPU usage does not exceed 95% in a short period and does not keep increasing. - No high CPU usage alarm is generated. In the following situations, the system may generate an alarm when CPU usage becomes high instantly and then clear this alarm rapidly: Cards just start. Information about all optical modules is queried at a time. Traffic volume increases instantly. This situation is a normal situation and does not affect the device operation. CPU usage of a CPU task process may become low or high, depending on the service volume and processing time. CPU usage is within a normal range as long as the system CPU usage does not exceed 80% and no high CPU usage alarm is generated. For possible causes and common troubleshooting procedures for high CPU usage, see the following: - For the S12700, see "High CPU Usage > Common Information" in S12700 Troubleshooting - Preliminary. - For the S7700 and S9700, see "High CPU Usage > Common Information" in S7700&S9700 Troubleshooting - Preliminary. - For the S1720, S2700, S3700, S5700, and S6700, see "High CPU Usage > Common Information" in S1720&S2700&S3700&S5700&S6700 Troubleshooting - Preliminary. - For the S9300, see "High CPU Usage > Common Information" in S9300 Troubleshooting - Preliminary. - For the S600-E, see "High CPU Usage > Common Information" in S600-E Troubleshooting - Preliminary.

How do I view the CPU usage of the SoftCo 9500?
In CLI mode, run the show cpu usage command to query the real-time CPU usage. You can also choose Resource Query > Monitors CPU usage in the web management system to view the CPU usage.
