谢谢回答，接计算机的端口是edge，不过就算undo掉也是获取不到，ter debug之前开了，啥也没出来。。。 谢谢
如果开Debug DHCP没有任何信息，说明交换价没有收到客户端的DHCP请求报文，所以不会下发地址，换个终端测试一下！
不好意思，忘记敲deb dhcp ser all了 敲了，有输出 *Jan 1 21:13:51:810 2013 H3C DHCPS/7/EVENT: Receive a DHCPDISCOVER message from Vlan-interface20. *Jan 1 21:13:51:810 2013 H3C DHCPS/7/EVENT: No matching network for the client. *Jan 1 21:14:23:097 2013 H3C DHCPS/7/PACKET: From 0.0.0.0 port 68, interface Vlan-interface20 Message type: REQUEST (1) Hardware type: 1, Hardware address length: 6 Hops: 0, Transaction ID: 2256444185 Seconds: 0, Broadcast flag: 0 Client IP address: 0.0.0.0 Your IP address: 0.0.0.0 Server IP address: 0.0.0.0 Relay agent IP address: 0.0.0.0 Client hardware address: 3c2c-30ac-9af4 Server host name: not configured Boot file name: not configured DHCP message type: DHCPDISCOVER (1) *Jan 1 21:14:23:097 2013 H3C DHCPS/7/EVENT: Receive a DHCPDISCOVER message from Vlan-interface20. *Jan 1 21:14:23:097 2013 H3C DHCPS/7/EVENT: No matching network for the client. *Jan 1 21:14:27:345 2013 H3C DHCPS/7/PACKET: From 0.0.0.0 port 68, interface Vlan-interface20 Message type: REQUEST (1) Hardware type: 1, Hardware address length: 6 Hops: 0, Transaction ID: 2256444185 Seconds: 1024, Broadcast flag: 0 Client IP address: 0.0.0.0 Your IP address: 0.0.0.0 Server IP address: 0.0.0.0 Relay agent IP address: 0.0.0.0 Client hardware address: 3c2c-30ac-9af4 Server host name: not configured Boot file name: not configured DHCP message type: DHCPDISCOVER (1) 感谢帮助，添麻烦了

我看了看，应该是这句： No matching network for the client. 。。。 但。。。配的也没错啊。。我觉得
你看看地址池的名称是否正确
地址池这句，我印象中可以不敲，我敲了，然后我也看到大小写不同，但我试了，地址池命名的时候有大写，但在vlan int接口上引用，系统自动转小写（至少dis cu上就这样，改都没用），我先换个简单的试试，谢谢帮助
interface Vlan-interface20 下不用调用
ip pool名改简单，in vlan 20下undo 掉引用。。。还是报一样的错。。。 *Jan 1 21:37:45:335 2013 H3C DHCPS/7/EVENT: Receive a DHCPDISCOVER message from Vlan-interface20. *Jan 1 21:37:45:335 2013 H3C DHCPS/7/EVENT: No matching network for the client.
没仔细看配置，你在地址池下加上这条命令：network 192.168.10.254 mask 255.255.255.0 加上这就解决了，望采纳
摔。。。忘记了。。。。。不好意思不好意思耽误你时间，感谢感谢
