1 配置option 43 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 acip code 43 = 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; # --- AC IP option acip 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AC的IP地址的十六进制，也就是说在配置时只需把自己的AC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 AC1# 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--i 2.2.2.1 AP1 00:0b:0e:90:01:00 E 11/18 E161/20 04h08m AC1# 2 配置option 138 方案介绍通过在Linux 上配置DHCP Server为AP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; # --- AC 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。 2.4 检验配置效果 AC2#show capwap state index peer device state 1 2.2.2.20 : 32768 Run AC2#show capwap detail -----------CAPWAP CONTROL BLOCK---------- index is 0 Current State [ Idle ] Recent recieved request's sequence number [43] Recent recieved response's sequence number [0] Recent send request's sequence number [0] Retransmit Count [ 0 ] Sending msg queue length [ 0 ] Receive msg queue length [ 0 ] On line timers: My address [ 1.1.1.1 ] My address6 [ :: ] Peer address [ 2.2.2.20 ] Peer address6 [ :: ] Peer control port [ 5246 ] Peer data port [ 5247 ] Session ID [0] [ 0 ] Session ID [1] [ 0 ] Session ID [2] [ 0 ] Session ID [3] [ 0 ] Control socket [ 2057 ] Data socket [ 2058 ] Path MTU [ 1500 ] Am I AP [ 0 ] Over IPv4 [ 1 ] Local or Split [ 1 ] Local Switch [ 0 ] -----------CAPWAP CONTROL BLOCK---------- index is 1 Current State [ Run ] Recent recieved request's sequence number [141] Recent recieved response's sequence number [25] Recent send request's sequence number [25] Retransmit Count [ 0 ] Sending msg queue length [ 0 ] Receive msg queue length [ 0 ] On line timers: [echo interval ] My address [ 1.1.1.1 ] My address6 [ :: ] Peer address [ 2.2.2.20 ] Peer address6 [ :: ] Peer control port [ 32768 ] Peer data port [ 32769 ] Session ID [0] [ 0 ] Session ID [1] [ 0 ] Session ID [2] [ 0 ] Session ID [3] [ 0 ] Control socket [ 2057 ] Data socket [ 2058 ] Path MTU [ 1500 ] Am I AP [ 0 ] Over IPv4 [ 1 ] Local or Split [ 1 ] Local Switch [ 0 ] AC2#
