This example shows how to display statistics for all the current active network connections:
System(rw)->show netstat INET sockets Prot Recv-Q Send-Q Local Address Foreign Address State ICMP 0 0 0.0.0.0.* 0.0.0.0.* TCP 0 0 0.0.0.0.111 0.0.0.0.* LISTEN TCP 0 0 0.0.0.0.80 0.0.0.0.* LISTEN UDP 0 0 127.0.0.1.20033 127.0.0.1.20032 . . . OSPFIGP 0 0 0.0.0.0.* 0.0.0.0.* INET6 sockets Prot Recv-Q Send-Q Local Address Foreign Address State TCP 0 0 ::.23 ::.* LISTEN System(rw)->
