You might want to continuously diagnose problems on your network. The netdiag command continuously gathers and analyzes statistics, and performs diagnostic tests.
These diagnostic tests identify and report problems with your physical network or transport layers and suggest remedial action.
For a full description of the netdiag command along with all available options, see the netdiag man page.
Use the ping command to test whether your storage system can reach other IPv4 hosts on your network. To reach IPv6 hosts, use the ping6 command.
You must use the -b option with the ping6 command when pinging with jumbo packets. For the pinging to succeed with jumbo packets, the buffer must be large enough to reassemble IP fragments.
You can also use the pktt command to trace the packets sent and received in the storage system network.
