The default is IP.Target IP address Sends ICMP echo message by inputting IP address or host name ofdestination in order to verify network status.Repeat count [5] Sends ICMP echo message as many as count. The default is 5.Datagram size [100] Ping packet size. The default is 100 bytes.Timeout in seconds [2] It is considered as successful ping test if reply returns within the con-figured time interval. The default is 2 seconds.Extended commands [n] Adds the additional options. The default is no.Tab. 6.2 Options for PingThe following is an example of ping test 5 times to verify network status with IP address10.55.193.110.SWITCH# pingProtocol [ip]: ipTarget IP address: 10.55.193.110Repeat count [5]: 5Datagram size [100]: 100Timeout in seconds [2]: 2Extended commands [n]: nPING 10.55.193.110 (10.55.193.110) 100(128) bytes of data.108 bytes from 10.55.193.110: icmp_seq=1 ttl=255 time=0.058 ms108 bytes from 10.55.193.110: icmp_seq=2 ttl=255 time=0.400 ms108 bytes from 10.55.193.110: icmp_seq=3 ttl=255 time=0.403 ms
