[j-nsp] LACP Mux State detached on MX960

[sanz]

Hi,

I came across a new issue today which shows the lacp state detached on an
AE/Physical interface on one of our mx960s. I bounced that interface,
troubleshot physicals, removed the config out of the AE and put it back on,
it's still the same. Has anyone seen this before? I'd like to know why this
happens, could not dig more out of Juniper's KB.

We just have one member in *this* AE due to a few standards that we have in
place, Usually we have multiple members in the AEs.

be grateful to anyone who can share their knowledge on this.

Thanks,
