Transition Networks ION x222x / x32xx User Guide If you need to specify a WINS server for your Windows clients, you will need to include the netbios‐name‐servers option, e.g.: nano -w /etc/default/dhcp3-server option netbios-name-servers 192.168.1.1; Start and stop service sudo service isc-dhcp-server restart sudo service isc-dhcp-server start sudo service isc-dhcp-server stop (Credit: "Contributors to the Ubuntu documentation wiki") Configuration Example (ION Devices / Linux ISC) The example below shows a configuration for the ION S2220‐1013, S3220‐1014 and S3230‐1040 for the Linux ISC (Internet Sys‐ tems Corporation) DHCP Server that goes in the dhcpd.conf file which is usually, depending on Linux distribution, located in the /etc/dhcp directory. option space EMS; option EMS.serverip code 240 = string; subnet 192.251.220.0 netmask 255.255.255.0 { range 192.251.220.33 192.251.220.34; option routers 192.251.220.2; option subnet-mask 255.255.255.0; class "Transition ION S2220" { match if option vendor-class-identifier = "S2220"; vendor-option-space EMS; option EMS.serverip "192.251.220.103"; } class "Transition ION S3220" { match if option vendor-class-identifier = "S3220"; vendor-option-space EMS; option EMS.serverip "192.251.220.103"; } class "Transition ION S3230" { match if option vendor-class-identifier = "S3230"; vendor-option-space EMS; option EMS.serverip "192.251.220.103"; } } You should adjust the subnet, netmask, range, 'option routers' and 'option subnet‐mask' for your network. You should adjust the 'option EMS.serverip' to match the EMS' address in your network. You should restart the ISC DHCP server after making changes to the dhcpd.conf file. For most Linux distributions this can be done by executing /etc/init.d/isc‐dhcp‐server restart. 33472 Rev. J https://www.transition.com Page 614 of 700
