在Linux的服务器上搭建DHCP Server配置option配置案例
1、配置option 43实现MP-71自动联系MX
1.1功能需求及组网
组网图
方案介绍
通过在Linux 上配置DHCP Server为AP提供IP及option 43选项。
1.2配置思路
1)下载、安装DHCP Server 相关程序。
2)调试基本的dhcp启动服务、并验证能否获取ip。
3)配置option 43。
1.3配置文件
CentOS
Vi dhcpd.conf
ignore client-updates;
ddns-update-style ad-hoc;
option mxip code 43 = string;
subnet2.2.2.0 netmask 255.255.255.0 {
# --- default gateway
option routers 2.2.2.254;
option subnet-mask 255.255.255.0;
# --- mx ip
option mxip 80:0B:00:00:01:02:02:02:FE:0B:45:14;
# --- pool
range dynamic-bootp 2.2.2.1 2.2.2.19;
default-lease-time 21600;
max-lease-time 43200;
}
以十六进制格式表示IP，80为选项类型，0B为选项长度，表示后面内容的长度，0000为Server Type,固定为0000，01为后面AC的IP地址的个数，“02:02:02:FE为MX的IP地址的十六进制，也就是说在配置时只需把自己的MX地址X.X.X.X换算成十六进制替换掉即可。“:0B:45:14 ”为固定格式说明前面定义的是一串ip地址。
1.4检验配置效果
MX-8# show ap status
Flags: o = operational[1], c = configure[0], d = download[0], b = boot[0]
a = auto AP, m = mesh AP, p/P = mesh portal (ena/actv), r = redundant[0] i = insecure, e = encrypted, u = unencrypted
Radio: E = enabled - 20MHz channel, S = sentry
W/w = enabled - 40MHz wide channel (HTplus/HTminus)
D = admin disabled
IP Address: * = AP behind NAT
AP Flag IP Address Model MAC Address Radio 1 Radio 2 Uptime
---- ---- --------------- ------------ ----------------- ------- ------- ------
2 o--i2.2.2.1 MP-422 00:0b:0e:90:01:00 E 11/18 E161/20 04h08m
MX-8#
2、配置option 138实现AP220-E自动联系AC
2.1功能需求及组网
组网图
方案介绍
通过在Linux 上配置DHCP Server为AP220-E提供IP及option 138选项。
2.2配置思路
1)下载、安装DHCP Server 相关程序。
2)调试基本的dhcp启动服务、并验证能否获取ip。
3)配置option 138。
2.3配置文件
CentOS
Vi dhcpd.conf
CentOS
Vi dhcpd.conf
ignore client-updates;
ddns-update-style ad-hoc;
option acip code 138 = string;
subnet2.2.2.0 netmask 255.255.255.0 {
# --- default gateway
option routers 2.2.2.254;
option subnet-mask 255.255.255.0;
# --- mx ip
option acip 01:01:01:01;
# --- pool
range dynamic-bootp 2.2.2.20 2.2.2.39;
default-lease-time 21600;
max-lease-time 43200;
}
以十六进制格式表示IP，“01:01:01:01为AC Loopback 0 IP地址的十六进制，也就是说在配置时只需把自己的AC Loopback 0 IP地址X.X.X.X换算成十六进制替换掉即可。
