Configuring Maintenance Diagnosing the Network ping [ ip | ipv6 ] { ip_addr } [ -n count ] [ -l count ] [ -i count ] Test the connectivity between the switch and destination device. ip: The type of the IP address for ping test should be IPv4. ipv6: The type of the IP address for ping test should be IPv6. ip_addr: The IP address of the destination node for ping test. If the parameter ip/ipv6 is not selected, both IPv4 and IPv6 addresses are supported, such as 192.168.0.100 or fe80::1234. -n count: Specify the amount of times to send test data for Ping testing. The values are from 1 to 10 times; the default is 4 times. -l count: Specify the size of the sending data for ping testing. The values are from 1 to 1500 bytes; the default is 64 bytes. -i count: Specify the interval to send ICMP request packets. The values are from 100 to 1000 milliseconds; the default is 1000 milliseconds. The following example shows how to test the connectivity between the switch and the destination device with the IP address 192.168.0.10. Specify the ping times as 3, the data size as 1000 bytes and the interval as 500 milliseconds: Switch#ping ip 192.168.0.10 -n 3 -l 1000 -i 500 Pinging 192.168.0.10 with 1000 bytes of data : Reply from 192.168.0.10 : bytes=1000 time
