But I don't understand how there can be active ports with "Last Input Never"
I even have a port in my network where there is traffic on the port but the Last Input is still never:
GigabitEthernet2/0/5 is up, line protocol is up (connected)
Hardware is Gigabit Ethernet, address is xxxx.xxxx.xxxx (bia xxxx)
Description: <User/voice port>
MTU 1500 bytes, BW 100000 Kbit/sec, DLY 100 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Full-duplex, 100Mb/s, media type is 10/100/1000BaseTX
input flow-control is off, output flow-control is unsupported
ARP type: ARPA, ARP Timeout 04:00:00
Last input never, output 00:00:01, output hang never
Last clearing of "show interface" counters never
Input queue: 0/2000/0/0 (size/max/drops/flushes); Total output drops: 1389460
Queueing strategy: fifo
Output queue: 0/40 (size/max)
5 minute input rate 29000 bits/sec, 5 packets/sec
5 minute output rate 34000 bits/sec, 9 packets/sec
