Configuration Guide DHCP Relay Configuration
Ruijie# configure terminal
Ruijie(config)# service dhcp //Enable the dhcp relay
function
Ruijie(config)# ip helper-address 192.18.100.1 //Add an IP address
globally
Ruijie(config)# ip helper-address 192.18.100.2 //Add an IP address
globally
Ruijie(config)# interface GigabitEthernet 0/3
Ruijie(config-if)# ip helper-address 192.18.200.1 //Add an IP address on
the interface
Ruijie(config-if)# ip helper-address 192.18.200.2 // Add an IP address on
the interface
Ruijie(config-if)# end
Other Precausions on DHCP Relay Configuration
For layer 2 network devices, you must enable at least one of the option dot1x,
dynamic address binding and option82 functions when the cross-management
vlan relay function is required. Otherwise, only the relay function of
management VLAN can be enabled for the layer 2 device.
Precautions on DHCP option dot1x Configuration
1. This command works only when the configuration related to AAA/802.1x is
correct.
2. When this scheme is adopted, the IP authorization of the DHCP mode of
802.1x should be enabled.
3. This command cannot be used together with command dhcp option82
because they are conflicted.
4. When the IP authorization of the DHCP mode of 802.1x is enabled, the
MAC address and the IP address will also be bound. Therefore, IP
authorization and DHCP dynamic binding function cannot be enabled at the
same time.
Precautions on DHCP option82 Configuration
The DHCP option82 function and the dhcp option dot1x function cannot be
used at the same time because they are conflicted.
