Finger Service/process equivalent on IOS-XR

[pboehmer]

We are in progress of upgrading from ASR1004s (XE 3.16.08) to ASR9901 BNGs (7.5.2).  In doing so, we no longer have the ability to show connected PPPoE sessions using a simple "telnet {ROUTER} finger".  We have a Unix server that would issue the command and then parse the finger output for various accounting/management (like kicking off users).

What would the equivalent command/process for this be?  Am I overlooking something or are we looking at using netconf/gRPC?  Any insight would be greatly appreciated.

Cisco no Longer uses Finger Services.

Yes, I know that finger is no longer an option.  This is why I am asking for an equivalent function/command.

I am not familiar with BNG on ASR1K, finger, nor with PPPoE BNG sessions, as my [very] limited BNG experience was with IPoE sessions with DHCP Discover as FSoL on XRv9K. That said, have you looked at the 9K's "show subscriber session" command to see if that provides useful info for your needs?

Also... Xander Thuis (no longer with Cisco) produced a treasure trove of info on 9K BNG when he worked in the XR BU:

Yes.  As a stopgap, we are currently utilizing combination of SSH/XML to make the "show subscriber session username".  This works satisfactory, but we are facing an issue after a couple of hours with some kind of "resource depletion" and lose the ability to ssh/console into the router.  We have an open TAC case open on this issue (possible bug in 7.5.2??). 

In the end, I am just looking for some direction on the best/preferred/most efficient way to pull PPPoE subscriber data.
