Impact on the System

When the alarm is generated, the services are not affected. If the number of created sessions reaches the maximum number of sessions supported by the CGN device, new sessions fail to be created.

Possible Causes

The proportion of configured user tables to the total supported ones on a service board's forwarding engine reached a specified threshold.

Procedure

1.Run the display nat user-information command. Then check the information of NAT users whether the proportion of used NAT user tables reaches the specified threshold.

  • If the proportion reaches the specified threshold, go to Step 2.
  • If the proportion does not reach the specified threshold, go to Step 3.

2.Run the nat alarm user-table threshold command in the system view to increase the threshold. Check whether the trap is cleared.

  • If the trap is cleared, go to Step 4.
  • If the trap persists, go to Step 3.

3.Collect trap, log, and configuration information, and then contact technical support personnel.

4.End.
