Hi,
On one of our N7K, we have some packets dropped by the COPP policy in the class-default class-map. :
Partial results of "show policy-map interface control-plane" not so long after clearing the counters :
class-map class-default (match-any)
set cos 0
police cir 100 kbps , bc 250 ms
module 1 :
conformed 12210790 bytes; action: transmit
violated 201870 bytes; action: drop
module 2 :
conformed 8399646 bytes; action: transmit
violated 0 bytes; action: drop
module 3 :
conformed 34518233 bytes; action: transmit
violated 6186895 bytes; action: drop
What would be the best way to figure out what traffic is dropped by the policy ? Is there any logging possible ?
Thanks,
Laurent

There is still no logging possible.
What can be done is piping the class-default-traffic to some port and then analyze it with wireshark or some similar tool. But as far as I know, this still cannot be done by default - at least with NX-OS 4.2(4) we had to reprogram the module with assistance from TAC. I suggest you contact your support partner in this matter.

Anyone know if the class-map type logging/policy-map type logging features are planned for NX-OS?

Hi, were you able to find out which packets are being dropped by the class-default?
