Sorry for the simple question, but there is a command that will allow you to view the statistics of packets and I cannot remember what it is.
For example, I am looking for how many packets of a certain size.

Thanks edison,
But I seem to remember that I could see the actual packet size and how many of each packet of a certain size.
Something like
24 bytes 10397
1472 bytes 100345
Do you recall anything like this?

Sorry Edison, I realize this doing the same thing, but I seem to remember the format was much different.
Thanks.

Hello, I know this thread is "only" 11 years old.. anyway the command is "show interface <int> counters detailed" but it may not be available on all platforms/versions. Below is from a Nexus sw running 7.3(x). Same command is not available on Cat 6880 running 15.1(x) for instance.

#metoo ... searching for this after that long time and just few days later than you! :-)
Thanks a lot for this refreshing of my memory, as I stumbled upon this a long time ago... Have a good time!

Hi Richard,
Would you elaborate what exactly are you trying to view?
Are you looking for "show ip traffic" command?
This command gives details of IP, ICMP, UDP, TCP, ARP, BGP, EIGRP, OSPF etc packets.
08-14-2009 07:21 AM
I am looking for (and the show buffers may be doing this) packets only and how many of each size are being passed through an interface.
I have seen it before and it was like a summary and showed a list of the packet sized and how many of each.

Richard,
The output is as summarized as it can get :)

Thanks buddy, you are right.
I appreciate your help edison.
I must be remembering something else
08-14-2009 07:25 AM
Probably "show ip accounting" will help you. You need to enable IP accounting on the interface before using it.
It provides outputs like below.
#sh ip accounting
Source Destination Packets Bytes
Accounting data age is 0
Let me know if it helps or not.
08-14-2009 07:30 AM
Thanks, but I tried that and it shows individual packets.
I seem to remember there was a list of packet sizes and how many of each size had been sent.
I could be remembering incorrectly.
Thanks for the assistance.
08-14-2009 08:36 AM
Perhaps you're remembering flow cache's summary stats?
e.g.
router#sh ip cache f
IP packet size distribution (437276353 total packets):

Eurika!!!
I think that is it.
Thanks Joseph.
Thank you everyone.

I recommend you run show controllers ethernet-controller X where X is your port.
Hope this helps.
