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 

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 bundle.

Chassis' not mentioned above will only support 8 members per 

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