30.7 DHCPv6 Troubleshooting
If the DHCPv6 clients cannot obtain IPv6 addresses and other network parameters, the following procedures
can be followed when DHCPv6 client hardware and cables have been verified ok:
 Verify the DHCPv6 server is running, start the related DHCP v6 server function if not running;
 If the DHCPv6 clients and servers are not in the same physical network, verify the router responsible
for DHCPv6 packet forwarding has DHCPv6 relay function. If DHCPv6 relay is not available for the
intermediate router, it is recommended to replace the router or upgrade its software to one that has a
DHCPv6 relay function;
 Sometimes hosts are connected to the DHCPv6 enabled switches, but can not get IPv6 addresses. In
this situation, it should be checked first whether the ports which the hosts are connected to, are
connected with the port which the DHCPv6 server is connected to. If connected directly, it should be
checked then whether the IPv6 address pool of the VLAN which the port belongs to, is in the same
subnet with the address pool configure in the DHCPv6 server; If not connected directly, and any layer
three DHCPv6 relay is configured between the hosts and the DHCPv6 server, it should be checked first
whether an valid IPv6 address has been configured for the switch interface which the hosts are
connected to. If not configured, configure an valid IPv6 address. If configured, it should be checked
whether the configured IPv6 address is in the same subnet with the DHCPv6 server. If not, please add
it to the address pool.
