27. Configuring The DHCP server
Revision 1.14.3

RX1000/RX1100™
Assign a client at switch port 3 address 192.168.1.103.
Assign multiple clients at switch port 4 dynamic addresses 192.168.1.151 through 192.168.1.200.
The router serves as the default gateway.
1.
Enable eth1 in the 'Edit Network Interfaces' menu.
2.
Add a new subnet, and configure it for network address 192.168.1.0 with netmask
255.255.255.0.
3.
Enable the 'Disable NAK of option82 clients for this subnet?' option to prevent confusing some
DHCP clients due to the client being on the same network as the DHCP server and the DHCP
relay agent (the switch).
4.
Save it then edit the subnet just created and click 'Edit Client Options'.
5.
Set default routers to 192.168.1.1 and save it.
6.
Click 'add an address pool' to the subnet.
7.
Set the address range to 192.168.1.102 to 192.168.1.102.
8.
Click 'Create'.
9.
Edit the pool by clicking on the link for the pool with address range 192.168.1.102 -
192.168.1.102.
10. Click 'add an option82 client'.
11. Give the client a unique alpha numeric name (for example client0102).
12. Set the remote id to the switch MAC address (00:0A:DC:11:22:00 in this case).
13. Set the circuit id to the switches circuit id identifier to the port (00:01:00:02 for VLAN 1 port
2 on a RuggedCom switch).
14. Click 'Create'.
15. Click 'Save'.
16. Repeat steps 6) through 15) for clients 192.168.1.103 changing the pool address range and
circuit id.
17. Repeat steps 6) through 15) for port 4 using the address range 192.168.1.151 to
192.168.1.200 and the circuit id for port 4.
18. Restart the DHCP server or apply changes.
27.1.2.4. Multiple Subnets On Separate VLANs Using Option82 On One Switch
In this example the eth1 interface is provided with IP address 192.168.1.1/24
A switch connected to eth1 and using address 192.168.1.2/24
The switch port 1 is connected to the router while its ports 2 through 8 provide DHCP relay support.
The switch has its DHCP relay server address set to router's address 192.168.1.1. The switch has all
ports in VLAN 1. The switch base MAC address is 00:0A:DC:11:22:00.
