That is the exact config I used also, from the same webpage
I tried both CEF and process - although the traffic I wanted to see was through
the router and not to the router. I didn't even see a single packet.
I ended up spanning the traffic from the switch.
The ASR1k supports the" easy style" one line embedded capture also, and just
works

Has anyone used this?
I have used it on other IOS-XE routers 44xx/3xxx with no issues.
My captures are empty on the ASR-920
Code running is:
03.18.01.SP.156-2.SP1-ext
Any experiences greatly welcomed.

Hi Nick,
What traffic are you trying to capture? I got this working as per these notes
(I had done something similar on ASR1000s but it turns out the syntax is
slightly different on the ASR920):
https://null.53bits.co.uk/index.php?page=embedded-packet-capture-epc
However that was a while ago, if I recall correctly I had was PPPoE traffic
tagged in a specific VLAN that I wanted to inspect and this wasn't showing up
in the traffic capture so I ended up having to SPAN the port on the
neighbouring device. So I think it's not perfect and possibly not even sure its
supported. I didn't bother with TAC as the SPAN worked fine and I haven't
needed it since.
Cheers,
James.
