When invoked with theÂ â€“i flag,Â netstat displays statistics for the network interfaces currently configured. If theÂ â€“a option is also given, it printsÂ all interfaces present in the kernel, not only those that have been configured currently. OnÂ vstout, the output fromÂ netstat will look like this:
# netstat -i Kernel Interface table Iface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flags lo 0 0 3185 0 0 0 3185 0 0 0 BLRU eth0 1500 0 972633 17 20 120 628711 217 0 0 BRU
TheÂ MTU andÂ Met fields show the current MTU and metric values for that interface. TheÂ RX andÂ TX columns show how many packets have been received or transmitted error-free (RX-OK/TX-OK) or damaged (RX-ERR/TX-ERR); how many were dropped (RX-DRP/TX-DRP); and how many were lost because of an overrun (RX-OVR/TX-OVR).
