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。

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

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

4)下载、安装DHCP Server 相关程序。

5)调试基本的dhcp启动服务、并验证能否获取ip。

6)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;

subnet 2.2.2 .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-boot p 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。
