Objective
- 平- 测试 Internet 控制消息协议 (ICMP ) 主机的可达性。
- tcping - 调试传输控制协议（TCP ) 连接/ping 到给定的目的地或端口组合
- 转储- 显示网络上的流量
- 追踪路线- 跟踪到 IPv4 地址的路由以检查路径
Environment
CloudGenix
Procedure
在设备上运行以下命令CLI.
控制计数 (-c) 和 ping 数据包大小 (-s) 的 ping 示例
ION-1# ping controller1 8.8.8.8 args="-c 3 -s 1400" PING 8.8.8.8 (8.8.8.8): 1400 data bytes 1408 bytes from 8.8.8.8: seq=0 ttl=59 time=50.710 ms 1408 bytes from 8.8.8.8: seq=1 ttl=59 time=50.590 ms 1408 bytes from 8.8.8.8: seq=2 ttl=59 time=50.568 ms
TCP： tcpping 接口 dst-ipv4:port
tcpping controller1 google.com:80 tcpping connected to 216.58.203.174:80 time=2ms tcpping controller1 yahoo.com:80 tcpping connected to 206.190.36.45:80 time=28ms
TCP转储： tcpdump interface=接口名称或编号（args=“”|显示|保存文件=文件名）
示例：主机上的 tcpdump 过滤IP8.8.8.8，protocol = icmp，并显示以太网帧信息（-e）
ION-1# tcpdump controller1 args=" -e host 8.8.8.8 and icmp" show tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 14:06:13.488774 00:50:56:92:30:be > 00:50:56:92:8b:1a, ethertype IPv4 (0x0800), length 98: 192.168.30.10 > 8.8.8.8: ICMP echo request, id 12410, seq 0, length 64 14:06:13.539514 3e:2d:5f:3a:be:bd > 00:50:56:92:30:be, ethertype IPv4 (0x0800), length 98: 8.8.8.8 > 192.168.30.10: ICMP echo reply, id 12410, seq 0, length 64
追踪路线： traceroute 接口 dst-ipv4 (args=" ")
ION-1# traceroute 1 8.8.8.8 traceroute to 8.8.8.8 (8.8.8.8) from 192.168.1.1, 30 hops max, 46 byte packets 1 10.73.99.1 (10.73.99.1) 0.661 ms 0.572 ms 0.827 ms 2 208.184.44.129.IPYX-118386-ZYO.zip.zayo.com (208.184.44.129) 0.752 ms 1.015 ms 0.938 ms 3 ge-11-1-4.mpr1.dfw5.us.zip.zayo.com (208.185.28.181) 1.218 ms 1.320 ms 1.207 ms 4 ae5.mcs1.dfw2.us.zip.zayo.com (64.125.28.85) 2.558 ms 2.429 ms 2.413 ms 5 ae1.cs1.dfw2.us.eth.zayo.com (64.125.28.124) 2.067 ms 2.229 ms 1.971 ms 6 * * * 7 64.125.15.61 (64.125.15.61) 2.052 ms 1.923 ms 1.902 ms 8 108.170.252.129 (108.170.252.129) 2.006 ms 1.985 ms 108.170.240.193 (108.170.240.193) 2.027 ms 9 108.170.230.117 (108.170.230.117) 1.931 ms 108.170.231.71 (108.170.231.71) 2.188 ms 108.170.230.113 (108.170.230.113) 2.065 ms 10 dns.google (8.8.8.8) 2.047 ms 1.859 ms 1.899 ms
