Test network connectivity

Use the ping and traceroute commands to test network connectivity. When you ping an IP address, you send packets to a destination and wait for a response. If there is no response, the destination is not active. The ping command is useful during configuration if you have problems connecting to a hostname or IP address.

When you execute traceroute, the output shows the path a packet takes from your device to the destination IP address. It also lists all intermediate hops (routers) that the packet traverses to reach its destination, including the total number of hops traversed.

Check IPv4 connectivity

Check IPv6 connectivity

OS10# ping 100::1
                                 
                                 Type Ctrl-C to abort.
