Can we view the count of discarded packets on the WLC port?

[Rps-Cheers]

HI,

I have two question about wlc:

1\Is there any method to check drop packets on wlc interfaces or ports ? For example, the output just like "show interface e x/y " command on switch.

2\Whether we can capture data plane packets on wlc ? And how to do it ?

Thx

[Rps-Cheers]

Thanks for your reply, but it seems not useful.

I think this is what you search (output from a WLC 3504):
