Taral,

Currently AMD presents this information aggregated for all sniffing interfaces.

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

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.
