Currently AMD presents this information aggregated for all sniffing interfaces.

Feel free to propose it on our DCRUM Requests for Enhancements forum.

Hi Adam.


thanks. I will reqeust this. Meanwhile, if I need to grab more info about jumbo frames off AMD, how can I do that? Is there any command I can use please?

You can see it both on the AMD and in CAS.

On AMD, open /usr/adlex/log/rtm_perf.log file and look for pkts drppd too big metric in RTM network driver statistics section that increments with every sampling interval.

In CAS go to Tools -> Diagnostics -> AMD Statistics -> Individual AMD Packet Statistics report and look for Dropped_too_big_packets series on Packet distribution (driver level) chart.
