We are trying to implement tcp intercept on some brand new ASR1009x 
running IOS-XE 16.12.5 yet nothing is seen (sometimes).

So I found:
which states:
It has been confirmed that the feature TCP intercept is not supported on 
any IOS-XE routers due to architectural difference as compared to legacy 
IOS routers.

I opened a ticket with Cisco TAC and they confirmed that tcp intercept 
is not supported and will be removed from all IOS-XE documentation.

Yet upon rare occasion we do see some data.
Anyone have any update on that issue?
