NAT_1.3.6.1.4.1.2011.5.25.240.2.30 hwCGNNoPatAddrGroupThresholdAlarm

Trap Buffer Description

The number of IP addresses allocated from the no-pat public network address pool reached the threshold. (AddrGroupName=[AddrGroupName], InstanceType=[InstanceType], InstanceName=[InstanceName], Pre-IPNum=[IPNum], Threshold=[Threshold], Slot=[Slot], Cpu =[Cpu])

The number of used No-PAT address pools in a NAT instance reached the threshold.

In VS mode, this trap is supported only by the admin VS.

This alarm is supported only on NetEngine 8000 F1A.

Impact on the System

When the trap is generated, it does not affect services. If users continue to log in to the NAT device and the number of assigned IP addresses reaches the upper limit of the public address pool, the NAT device cannot assign IP addresses to users. As a result, subsequent users fail to get online.

Possible Causes

The proportion of used IP addresses to all IP addresses in a specified no-PAT address pool reached a specified threshold.

Procedure

1.Reduce used address number.

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