【命令】
Ping -I，-c，-I,-s,-t-vrf-WORD
【缺省情况】
缺省情况下，ping不带参数。
【视图】
系统视图
【参数】
-I Set source address 带源IP ping
-c Stop after sending count ECHO_REQUEST packets 设置发包个数（1-10000）
-i Set the interval of every packet 探测数目（1-10）
-s Specifies the number of data bytes to be sent 所发送数据包的报文大小（64-65500）
-t Set the IP Time to Live 指定数据包探测条数（1-255）
-vrf Select VPN routing instance ping vrf里地址，需带vrf名称
WORD Ping destination address or hostname 直接ping 域名或者目的IP，使用默认参数
【举例】
# 使用本机ip 访问114
host# ping -I 192.168.2.73 114.114.114.114

Traceroute用来追踪设备所经过的跳数
【命令】
traceroute (-i imcp) (-s source address) (-u udp)name
【缺省情况】
缺省情况下，默认使用udp探测追踪路由。
【视图】
#视图
【参数】
-i Use ICMP ECHO instead of UDP datagrams icmp探测
-s Chooses an alternative source address 带源地址探测
-u Udp port detect udp探测
WORD Trace route to destination address or hostname 探测目标域名或者ip
【使用指导】
需要设备网络连通。
【举例】
# 带源地址探测到114的跳数
host# traceroute -s 192.168.2.73 114.114.114.114

tcpSyn命令用来探测目标开放的端口
【命令】
Tcpsyn (-c Set packet count option ) (-w Set packet timeout option) hostname
【视图】
#视图
【参数】
-c Set packet count option 数据包计数选项（1.1000）默认3
-w Set packet timeout option 数据包超时选项（1-1000）默认1
HOSTNAME Destination domain 探测域名或者地址后面跟端口范围（0-65535）
【使用指导】
配置探测目标
【举例】
# tcp探测百度是否开放80端口
host# tcpsyn www.baidu.com 80
tcpsyn to 115.239.211.112:80
1 TCP ACK from 115.239.211.112:80
2 TCP ACK from 115.239.211.112:80
3 TCP ACK from 115.239.211.112:80!
