access-speed adjustment system-state threshold
Function
The access-speed adjustment system-state threshold command configures the system status threshold for decreasing the user access rate and the threshold for restoring the user access rate.
The undo access-speed adjustment system-state threshold command restores the default configuration.
By default, the system status threshold for decreasing the user access rate and the threshold for restoring the user access rate are as Usage Scenario.
This command is supported only on the NetEngine 8000 F1A.

Usage Guidelines
Usage Scenario
To change the default system status threshold for decreasing the user access rate and the threshold for restoring the user access rate, run the access-speed adjustment system-state threshold command.
By default, the system status threshold for decreasing the user access rate and the threshold for restoring the user access rate are as follows:| Item | Threshold for Decreasing the User Access Rate | Threshold for Restoring the User Access Rate |
|---|---|---|
| main-cpu-usage | 90 | 85 |
| main-memory-usage | 85 | 83 |
| access-queue | 4 | 2 |
| slot-cpu-usage | 85 | 84 |
| slot-memory-usage | 85 | 75 |
| ppp-cpcar-drop | 2 | 1 |
| ppp-receive-queue | 2 | 1 |
| pppoe-receive-queue | 2 | 1 |
| l2tp-queue | 10 | 5 |
| dhcp-slot-queue | 6 | 3 |
| fes-queue | 9 | 5 |
| lns-cpcar-drop | 2 | 1 |
| eap-cpcar-drop | 2 | 1 |
| cpu-usage | 90 | 85 |
