[j-nsp] Debugging subscribers on an ERX LNS

[Thomas Salmen]

Greetings,

I don't see much discussion of E-series troubles, issues, features, etc, on
this list - hopefully this isn't an M-series only list...

Anyways - I'm trying to come up with an easy way of running a per-subscriber
debug on an ERX configured as a LAC.

It's reasonably obvious that this can be done on a box terminating PPPoA or
PPPoE sessions, as there is a statically configured interface for each
subscriber which a debug profile can be applied to. However on an LNS there
is no interface until the subscriber session has been established - which is
usually the process which is failing, hence the debug.

The only current way of doing debugs is to enable on a per-LAC or per-box
basis - this doesn't scale to well, unfortunately.

Does anyone have any creative ways of doing this that they might be willing
to share? I've asked Juniper directly, and they're getting back to me - I
just though someone else might have figured out something as well.

Cheers,
Thomas
