Recommended action
To resolve this issue:
1.Execute the display nat statistics packet command in any view to identify whether the current bandwidth or history maximum bandwidth of the CGN card exceeds the maximum forwarding bandwidth.
- If the current bandwidth or history maximum bandwidth has approached the maximum forwarding bandwidth, go to step 2.
- If the current bandwidth or history maximum bandwidth does not approach the maximum forwarding bandwidth, go to step 3.
2.Expand the card capacity and identify whether the notification occurs again.
- If the notification does not occur any longer, the issue has been resolved.
- If the notification occurs again, go to step 3.
3.Collect alarm information and configuration data, and then contact H3C Support for help.

To resolve this issue:
1.Execute the display nat instance instance-name address-group command to identify whether the address group resource usage drops below the threshold.
- If the resource usage drops below the threshold set by the nat log port-block usage threshold command, go to step 4.
- If the resource usage is equal to or greater than the threshold set by the nat log port-block usage threshold command, go to step 2.
2.Execute the nat log port-block usage threshold command to set a greater port block usage threshold and verify if the notification occurs again.
- If the notification does not occur any longer, the issue has been resolved.
- If the notification occurs again, go to step 3.
3.Add resources to the address pool and verify if the notification occurs again.
- If the notification does not occur any longer, the issue has been resolved.
- If the notification occurs again, go to step 4.

This notification is generated when you fail to add an address range to a NAT address pool.
This notification might be generated when the following events occur:
The IP addresses on the subnet requested by a dynamic global address pool on the UP from the CP overlap with IP addresses in another global address pool.
The number of addresses in a global address pool on the UP has reached the upper limit.
System impact
You fail to add an address range to a NAT address pool. As a result, the NAT address pool cannot allocate addresses.

Recommended action
To resolve this issue:
1.Obtain the value for the hh3cNatTrapIPPoolFailReason field in the notification.
- If the value is The number of addresses in the global address pool has reached the upper limit, the number of addresses in the address pool has reached the upper limit and you cannot add new addresses to the address pool. Go to step 2.
- If the value is not The number of addresses in the global address pool has reached the upper limit, the address range to be added conflicts with the local address. Use the display nat ip-pool, display nat address-group, display nat port-block-group, or display nat server command to identify the public address conflicting with the address range to be added, and then go to step 3.
2.Reduce NAT addresses and verify if the notification occurs again.
- If the notification does not occur any longer, the issue has been resolved.
- If the notification occurs again, go to step 4.
3.Delete the public address conflicting with the address range to be added and verify if the notification occurs again.
- If the notification does not occur any longer, the issue has been resolved.
- If the notification occurs again, go to step 4.
4.Collect alarm information and configuration data, and then contact H3C Support for help.

To resolve this issue:
1.Execute the display nat user-table command to identify whether the number of user sessions reaches the upper limit of assignable resources for the port blocks.
- If the user session number has reached the upper limit, expand the pre-allocated port block size or configure extended port blocks, and then verify if the notification occurs again. If the notification occurs again, go to step 2.
- If the user session number does not reach the upper limit, go to step 2.
2.Collect alarm information and configuration data, and then contact H3C Support for help.

To resolve this issue:
1.Execute the display nat user-table command to identify whether the port usage of the NAT port block reaches or exceeds the threshold.
- If the port usage of the NAT port block is equal to or greater than the specified alarm threshold, go to step 2.
- If the port usage of the NAT port block is lower than the specified alarm threshold, go to step 3.
2.Execute the nat log port-block port-usage threshold command to set a greater port usage threshold for the port block and verify if the notification occurs again.
- If the notification does not occur any longer, the issue has been resolved.
- If the notification occurs again, go to step 3.
