很多時候想通過域名的方式測試網絡設備，但往往只能通過IP訪問，今天發現原來可以通過幾個命令來實現！
H3C設備配置：
[H3C]dns resolve [H3C]dns server 114.114.114.114 [H3C]ping www.baidu.com PING www.baidu.com (115.239.211.112): 56 data bytes, press CTRL_C to break Reply from 115.239.211.112: bytes=56 Sequence=1 ttl=53 time=8 ms Reply from 115.239.211.112: bytes=56 Sequence=2 ttl=53 time=7 ms Reply from 115.239.211.112: bytes=56 Sequence=3 ttl=53 time=7 ms Reply from 115.239.211.112: bytes=56 Sequence=4 ttl=53 time=9 ms Reply from 115.239.211.112: bytes=56 Sequence=5 ttl=53 time=7 ms --- www.baidu.com ping statistics --- 5 packet(s) transmitted
5 packet(s) received 0.00% packet loss round-trip min/avg/max = 7/7/9 ms
思科設備配置：
Cisco(config)#ip name-server 114.114.114.114 Cisco(config)#ip domain-lookup //開啓域名查找 Cisco(config)#do ping www.baidu.com Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 115.239.210.27, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 4/7/8 ms Cisco(config)#
好了，是不是很簡單？
