Show interface Last input

[deehusky79]

Hello...can someone explain to me why the last input of this active port shows never.

FastEthernet0/6 is up, line protocol is up (connected)

  Last input never, output 00:00:00, output hang never

9622019 packets output, 740900442 bytes, 0 underruns  

The other interface from the same switch (C2960) shows the expected outcome:

FastEthernet0/11 is up, line protocol is up (connected)

Last input 00:00:43, output 00:00:00, output hang never

1023135 packets input, 94092343 bytes, 0 no buffer

Thanks in advance for sharing your knowledge with me.

Hi,

What device is connected on that port and how is it connected to the switches? Is it using dual nics or teaming? Could be a device that just receives data on one ports and sends out  another port.

Thanks

HI John, even though it allows voice Vlan, only a Dell PC is connected directly to this port . And it doesn't use dual nics or teaming.

Hi,

Is that PC used for anything special? It could be the  PC receives more data than it sends. Some operating systems like Linux generate very little traffic when idle depending on their configuration.

Thanks
