Interface traffic on ASA

buffkata
Level 1
Level 1

Hi, 

I just noticed something on our ASAs  and was wondering if someone have seen this or if there is a better ezplanation for the difference between traffic(packets and bytes/s ) reported by an ASA on its  Physical Interfaces number  and nameif. 

Below is the output of show traffic and show interface inside - you can see that interface inside is on t0/9 but still counters reported by both commands are different ? 

 asa# sh int inside
Interface TenGigabitEthernet0/9 "inside", is up, line protocol is up
Hardware is bcm56801 rev 01, BW 10000 Mbps, DLY 10 usec
(Full-duplex), (10000 Mbps)
Input flow control is unsupported, output flow control is off

are you referring this, if so, this may be different pattern every 1 or 5minutes depends on the usage of the network ? of somthing else you referring ?

Not really - the interface input traffic reported with nameif inside should
be the same as t0/9 but it is not and there is a huge difference there.
I think this is because there of the dropped packets but still was not able
to find out anything online that can confirm that :
asa# sh int inside

3971284 packets input, 1080732198 bytes
6840386 packets output, 1521936904 bytes

1 minute drop rate, 0 pkts/sec
5 minute input rate 65 pkts/sec, 13767 bytes/sec
5 minute output rate 72 pkts/sec, 12558 bytes/sec
5 minute drop rate, 0 pkts/sec
