Configuring the Standard DHCP Mode for Huawei MA5600, you can also make a reference for HG8245 GPON and echolife HG8240, if you have the smae configuration.
This
topic is applicable to the scenario for specifying the corresponding DHCP
server groups for different users of the VLAN (the VLAN that is used when the
service ports are created).
Prerequisites
A
VLAN must be created. For details, see Configuring
a VLAN.
Procedure
1.
Configure the DHCP forwarding mode.
In
the global config mode, run the dhcp mode layer-3 standard command to configure the DHCP relay
mode to standard L3 DHCP relay mode (layer-3, standard). If keyword VLAN is selected andVLANID is
entered, this configuration takes effect only for this VLAN.
2.
Configure the DHCP server group.
a.
In the global config mode, run the dhcp-server command to create a DHCP server group.
·
group-number: Indicates the
number of the DHCP server group. It identifies a server group. You can run the display
dhcp-server all-group command
to query the DHCP server groups that are already configured and select a DHCP
server group number that is not used by the system.
·
ip-addr: Indicates the
IP address of the DHCP server in the DHCP server group. Up to four IP addresses
can be entered.
NOTICE:
The IP address of the DHCP server
configured here must be the same as the IP address of the DHCP server on the
network side.
b.
(Optional) Run the dhcp
server mode command
to configure the working mode of the DHCP server.
The
DHCP servers in the DHCP server group can work in the load balancing mode or
active/standby mode. By default, they work in the load balancing mode.
3.
Bind the DHCP server to the VLAN.
a.
In the global config mode, run the interface
vlanif command
to create a VLAN L3 interface.
The
VLAN ID must be the same as the ID of the VLAN described in the prerequisite.
b.
In the VLANIF mode, run the ip
address command
to configure the IP address of the VLAN L3 interface.
After
the configuration is completed, this IP address is used as the source IP
address for forwarding the IP packets in the VLAN at L3.
NOTICE:
·
If only an L2 device exists between the MA5600 and the DHCP server, the IP address of
the VLAN L3 interface needs to be in the same subnet as the IP address of the
DHCP server.
·
If the upper-layer device of the MA5600 is an L3 device, the IP address of the
VLAN L3 interface and the IP address of the DHCP server can be in different
subnets; however, a route must exist between the VLAN L3 interface and the DHCP
server. For details, see Configuring
the Route.
c.
In the VLANIF mode, run the dhcp-server command to bind the DHCP server to the
VLAN.
This
command requires parameter group-number, the value of which is
the number of the created DHCP server group.
Example
Assume
that server group 1 contains two DHCP servers working in active/standby mode,
with the maximum response time of 20s, the maximum count of response timeout of
10, the IP address of the primary server 10.1.1.9 and the IP address of the
secondary server 10.1.1.10. To bind server group 1 to users in VLAN 2 (with the
IP address of the L3 interface 10.1.1.101), do as follows:
huawei(config)#dhcp mode layer-3 standard
huawei(config)#dhcp server mode backup 20 10
huawei(config)#dhcp-server 1 ip 10.1.1.9 10.1.1.10
huawei(config)#interface vlanif 2
huawei(config-if-vlanif2)#ip address 10.1.1.101 24
huawei(config-if-vlanif2)#dhcp-server 1
