Thanks - I didn't realize til after that the docs were for e-series.  My
question was more geared on MX side of things.

Appreciate it..

Not to be pedantic, but turns out it's now 802.1AX :-).

I notice your reference was to a Juniper ERX platform. I can't tell you much
here as I haven't worked with these before.

But if you're looking at JUNOS-based routers, on the M120, M320, MX-series
and all T-series routing platforms, you can have up to 16 members per LAG

Chassis' not mentioned above will only support 8 members per bundle.

Platforms can have up to 128 individual bundles, but you'll probably run out
of ports before you get that far :-).

LACP is the common denominator.
