There isn't any such featre (as of yet) if you are talking about an ASR9000 series device? If so then yeah, nothing yet. I am rather shocked by this but I've been in contact with TAC over various issues with IOS-XR and the ASR9K's and they have confirmed to me there is no "proper" packet-capture feature yet. Even with Typhoon line cards and RSP440s. I would assume this feature is perfectly possible and simply hasn't dropped yet, Cisco haven't confirmed or denided that for me yet though. The best you can do is apply ACLs to the line card to check if a packet that matches the ACL is either ingressing or egressing the PHY or NP or FIA you assign the ACL to. This basically: https://supportforums.cisco.com/document/122386/asr9000xr-how-capture-dropped-or-lost-packets Note before: that is a service affecting operation. You can run SPANs in IOS-XR if you have somewhere to SPAN a port to. Also you can use the interface "monitor" command, "monitor interface xxx" which isn't great but sometimes anything is better than nothing. Cheers, James,
