Deployment Guide

• Option 43 sub-option code — The option 43 sub-option code for the ExtremeWireless APs is type 1
(0x1).
• IP addresses of Extreme Campus Controller
To configure the vendor encapsulated option on a Linux server, you must do the following:
• Define an option space.
• Define some options in that option space.
• Provide values for the options.
• Specify that this option space should be used to generate the vendor-encapsulated-options option.
To configure DHCP option 43:
1. Modify the dhcp.conf file (modifications are in bold).
[root@localhost ~]# vim /etc/dhcpd.conf
authoritative;
ddns-update-style interim;
ignore client-updates;
option space HAP;
option HAP.HWC code 1 = text;
subnet 10.100.1.0 netmask 255.255.255.0 {
range 10.100.1.10 10.100.1.254;
option subnet-mask 255.255.255.0;
option slp-directory-agent false 10.1.100.11;
option domain-name-servers 10.100.1.2;
option domain-name "bpmgmt.com";
option routers 10.100.1.1;
default-lease-time 40000;
}
…
subnet 10.100.4.0 netmask 255.255.255.0 {
range 10.100.4.100 10.100.4.254;
option subnet-mask 255.255.255.0;
option slp-directory-agent false 10.100.4.46, 10.100.4.47;
option domain-name-servers 10.100.1.2;
option domain-name "bpmgmt.com";
option routers 10.100.4.1;
default-lease-time 40000;
Vendor Class for ExtremeWireless APs:
class "HAP" {
match option vendor-class-identifier;
}
subclass "HAP" "AP3935" {
vendor-option-space HAP;
option HAP.HWC "10.100.2.36, 10.100.2.22";
}
