Case Study: Configuring the DHCP Server in Linux Distributions

ExtremeXOS software version 12.5.1. was used in this case study.
As mentioned earlier, Extreme Networks Auto Configuration feature is architected using standards-based protocols such as
DHCP and TFTP. The DHCP server could be running in any operating system and hardware. However, it should provide support
for vendor-class identifier and vendor-encapsulated options. A sample or snippet of the DHCP configuration file (dhcpd.conf) is
provided below that can be used in standard Linux distributions such as RedHat Enterprise Linux (RHEL), or Fedora Core, etc.
option space EXTREME;
option EXTREME.tftp-server-ip code 100 = ip-address;
option EXTREME.config-file-name code 101 = text;
option EXTREME.snmp-trap-ip code 102 = ip-address;
class "PRIMECORP-Edge-without-POE" {
match if (option vendor-class-identifier = "X250e-48t");
vendor-option-space EXTREME;
option EXTREME.tftp-server-ip 10.120.89.80;
option EXTREME.config-file-name "primecorp_x250e_edge.cfg";
option EXTREME.snmp-trap-ip 10.120.91.89;
}
class "PRIMECORP-Edge-x450e-POE" {
match if (option vendor-class-identifier = "X450e-48p");
vendor-option-space EXTREME;
option EXTREME.tftp-server-ip 10.120.89.80;
option EXTREME.config-file-name "primecorp_x450e_edge.xsf";
option EXTREME.snmp-trap-ip 10.120.91.89;
}
subnet 10.127.8.0 netmask 255.255.255.0 {

allow members of "PRIMECORP-Edge-without-POE";
allow members of "PRIMECORP-Edge-x450e-POE";
}
