  這里,我們?cè)賮碇v解一下華為路由器DHCP的最后一部分:華為3COM路由器DHCP Client配置。希望本文能給大家?guī)硪恍﹨⒖肌?/div>  
 
                       
  根據(jù)前面兩節(jié),我們已經(jīng)對(duì)華為3COM路由器DHCP Server配置和華為3COM路由器DHCP Relay配置的步驟有所掌握了,這里我們就再說一下***一部分:華為3COM路由器DHCP Client配置,具體步驟和內(nèi)容如下:
華為3COM路由器DHCP Client配置1。 需求
路由器作為DHCP Client,獲取接口的動(dòng)態(tài)IP地址。
主要用在使用路由器的以太網(wǎng)接口通過LAN方式接入公網(wǎng)的組網(wǎng)。

 - #
 - interface NULL0
 - #

 - user-interface vty 0 4
 - #
 - return
 
華為3COM路由器DHCP Client配置4。 驗(yàn)證
通過disp int 可以查看接口獲取的IP地址
- [Quidway]disp int e 1/0/0
 - Ethernet1/0/0 current state :UP
 - Line protocol current state :UP
 - Description : Ethernet1/0/0 Interface
 - The Maximum Transmit Unit is 1500, Hold timer is 10(sec)
 - Internet Address is 202.101.xx.4/24, acquired via DHCP
 - IP Sending Frames' Format is PKTFMT_ETHNT_2, Hardware address is 00e0-fc45-2ca7
 - Media type is twisted pair, loopback not set, promiscuous mode not set
 - 100Mb/s, Full-duplex, link type is autonegotiation
 - Output flow-control is disabled, input flow-control is disabled
 - Output queue : (Urgent queue : Size/Length/Discards) 0/50/0
 - Output queue : (Protocol queue : Size/Length/Discards) 0/500/0
 - Output queue : (FIFO queuing : Size/Length/Discards) 0/75/0
 - Last 300 seconds input rate 0.00 bytes/sec, 0.00 packets/sec
 - Last 300 seconds output rate 0.00 bytes/sec, 0.00 packets/sec
 - Input: 406 packets, 57174 bytes, 406 buffers
 - 218 broadcasts, 0 multicasts, 0 pauses
 - 0 errors, 0 runts, 0 giants
 - 0 crc, 0 align errors, 0 overruns
 - 0 dribbles, 0 drops, 0 no buffers
 - Output:268 packets, 37113 bytes, 269 buffers
 - 86 broadcasts, 19 multicasts, 0 pauses
 - 0 errors, 0 underruns, 0 collisions
 - 0 deferred, 0 lost carriers
 
華為3COM路由器DHCP Client配置5。 提示
1、 為了實(shí)現(xiàn)上網(wǎng)功能必須指定默認(rèn)路由器。該網(wǎng)關(guān)的地址可以通過debugDHCPclient packet獲得。將設(shè)備的默認(rèn)路由指向該網(wǎng)關(guān)就可以了。該默認(rèn)網(wǎng)關(guān)一般都是固定不變的,不會(huì)隨地址的獲取和釋放而變化。
2、 該配置經(jīng)常需要和NAT配置結(jié)合起來,實(shí)現(xiàn)內(nèi)網(wǎng)用戶上網(wǎng)功能。
