Trap Buffer Description

The IPv6 NDRA prefix usage of the domain [domainName] reached the upper threshold. (Domain index = [domainIndex],Threshold=[threshold])

The IPv6 NDRA prefix usage of the domain reached the upper 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

If this problem is not solved, IPv6 prefixes allocated using NDRA in the address pool of the domain may be used up. As a result, new users cannot obtain IPv6 prefixes using NDRA and are unable to get online.

Possible Causes

A large number of users got online from the domain, causing the number of IPv6 prefixes allocated using NDRA to reach the threshold.

Procedure

1.Run the display domain domain-name command to view the IPv6 address threshold.

a.If the value of IPv6-warning-threshold configured in the domain ranges from 1 to 99, go to Step 2.

b.If IPv6-warning-threshold is not configured or is set to 100, go to Step 4.

2.Run the display ipv6-pool pool-usage command to check whether the number of users getting online using IPv6 prefixes allocated using NDRA from the local address pool of the domain reaches the threshold specified in the network planning.

a.If so, go to Step 5.

b.If not, go to Step 3.

3.Run the ipv6-pool command in the domain to increase the number of referenced delegation address pools, or run the access-type command in the BAS interface view to configure new users to get online from other domains. Check whether this alarm is generated after 30 minutes.

a.If so, go to Step 5.

b.If not, go to Step 4.

4.Collect alarm information, log information, and configuration information, and contact technical support personnel.

5.End.
