the OLT
l Forwarding DHCP and broadband packets: 11.11.11.11
l Forwarding CM management packets: 11.11.12.11
IP address of the DHCP
server
DHCP server assigning IP addresses to CMs and media terminal
adapters (MTAs): 192.168.10.10-192.168.10.11
Procedure
Step 1 Set the IP address of the VLAN Layer 3 interface.
huawei(config)#vlan 100 smart
huawei(config)#interface vlanif 100
huawei(config-if-vlanif100)#ip address 10.10.224.1 255.255.255.0 //Set the IP
address of the DHCP domain gateway for CMs.
huawei(config-if-vlanif100)#quit
Step 2 Configure the working mode of the DHCP relay to Layer 3 Option 60.
In DHCP Option 60 mode, a DHCP server group is selected according to the Option 60 domain
name in DHCP packets. Users in this mode are identified by domain information of packets,
which differentiates various service types in a VLAN. Ensure that the Option 60 domain name
and the DHCP server group bound to the Option 60 domain name are configured beforehand.
huawei(config)#dhcp mode layer-3 Option60
Several minutes may be required and no action can be taken during this period
Are you sure to perform this operation? (y/n)[n]: y
Step 3 Set the IP addresses of the servers in a DHCP server group.
huawei(config)#dhcp-server 0 ip 192.168.10.10 192.168.10.11 //Configure DHCP
server group 0 to assign IP addresses to CMs.
Step 4 Create a DHCP Option 60 domain.
huawei(config)#dhcp domain docsis //Create Option 60 domain name docsis for CMs.
huawei(config-dhcp-domain-docsis)#dhcp-server 0 vlan 100 //Bind DHCP server
group 0 to the DHCP domain where the CMs locate. After the configuration, the CMs
in the DHCP domain are corresponded to DHCP server group 0.
huawei(config-dhcp-domain-docsis)#quit
