Configuring the NAT Alarm Function

For how to configure the NAT alarm function, see Table 1.

**Table 1** Enhanced functions
Operation	Command
Enable the function of sending logs and alarms if the number of private addresses corresponding to a public address exceeds the threshold.	nat srcip-car used-up alarm enable
Set the alarm threshold for the number of private addresses corresponding to a public address.	nat srcip-car used-up alarm threshold threshold
Enable log and alarm sending upon the 3-tuple NAT address pool port usage.	Run the nat full-cone global alarm ip-pool port-number threshold trap enable command to enable log and alarm sending upon exhaustion of ports in the NAT address pool. Run the nat full-cone global alarm ip-pool port-number threshold command to set the alarm threshold of the port usage of the NAT address pool.
Enable log and alarm sending upon the port usage of a single public IP address in the 3-tuple NAT address pool.	Run the nat full-cone global alarm public-ip port-number threshold trap enable command to enable log and alarm sending upon the port usage of a single public IP address in the address pool. Run the nat full-cone global alarm ip-pool port-number threshold command to set the alarm threshold of the port usage of a single public IP address.
Enable alarm sending upon the usage of public IP addresses in the NO-PAT address pool.	Run the nat no-pat global alarm ip-pool threshold trap enable command to enable alarm sending upon exhaustion of public IP addresses. Run the nat no-pat global alarm ip-pool threshold threshold-value command to set the alarm threshold of the public IP address usage of the NAT address pool.
Configure the function of sending the alarm on the port usage in a 3-tuple NAT scenario.	In a 3-tuple NAT scenario, to monitor the total usage of ports whose IP addresses are in the address pool or the usage of the port whose IP address is in the address pool, configure the function of sending the alarm on the port usage. When the port usage reaches the threshold, the FW sends an alarm to the NMS. Configure the function of sending the alarm on the port usage for the address pool. When the total usage of ports whose IP addresses are in the address pool hits the threshold, the FW sends an alarm to the NMS. Enable the function of sending the alarm on the port usage. nat full-cone global alarm ip-pool port-number threshold trap enable This function is disabled by default. Set a threshold for the port usage. nat full-cone global alarm ip-pool port-number threshold threshold-value The default threshold for the port usage is 80%. Configure the function of sending the alarm on the port usage for specific public IP addresses in the address pool. When the usage of the port whose IP address is in the address pool reaches the threshold, the FW sends an alarm to the NMS. Enable the function of sending the alarm on the port usage. nat full-cone global alarm public-ip port-number threshold trap enable This function is disabled by default. Set a threshold for the port usage. nat full-cone global alarm public-ip port-number threshold threshold-value The default threshold for the port usage is 80%.
Sets the interval and threshold of sending port conflict alarms	snmp-agent nat trap { interval interval \| threshold threshold }
