Parameters

Name	Meaning
OID	Indicates the MIB object ID of the alarm.

Impact on the System

A client obtains the PD prefix, but service data fails to be forwarded.

Possible Causes

The number of PD routing entries on the DHCPV6 relay agent is limited. When there are an excessive number of online DHCPv6 PD clients, the number of PD routing entries generated on the DHCPv6 relay agent for such DHCPv6 PD clients may exceed the upper limit. As a result, no more PD routing entry can be generated on the DHCPv6 relay agent. The DHCPv6 relay agent has no PD routing entry corresponding to a client. As a result, service data of the client fails to be forwarded.

Procedure

Run the undo dhcpv6 client pd command on some interfaces to disable the DHCPv6 PD client function to reduce the number of DHCPv6 PD clients so that the number of PD routing entries on the DHCPv6 relay agent does not exceed the upper limit.
