DHCP clients failed to come online
Symptom
DHCP clients cannot come online, although network connections and interface IPoE configurations are correct.
Analysis
By default, DHCPv4 and DHCPv6 clients use ISP domains specified in Option 60 and Option 16, respectively. If the DHCP packets do not carry the options, the DHCP client uses the ISP domain specified in the IPoE configuration on the interface. If the specified ISP domain does not exist on the BRAS, the DHCP client cannot come online.
Solution
To solve the problem:
Use debug commands or a packet analyzer to check DHCP packets from the DHCP client.
If the DHCPv4 packet carries Option 60 or the DHCPv6 packet carries Option 16, verify that the ISP domain in the option exists on the BRAS.
If the DHCP packet does not carry Option 60 or Option 16, verify that the ISP domain specified on the interface exists on the BRAS.
