thanks.
i don't think lacp is required for bundle links to work. i had done bundle
links between cisco to cisco, juniper to juniper without lacp.
i tried to avoid confusion of lacp between two switches before i know for sure

That's correct but in this case one is LACP (802.3ad) and one is not so it
won't bring up the links at all.

well, both ends are copper links, but links on 3750 are f10/100 and that of
juniper are 10/100/1000.

It's strange
We had issues before with LAGs between cisco and SRX. The links were
showing as up and then intermittently went down. We fixed it by setting
the LACP periodic interval to slow and it corrected it all.
Seems that cisco defaults to slow and Juniper to fast. Just a mismatch in
LACP packets.
HTH
Might it be that the EX can't link to FE, but only to GE? I know the -F only
takes gig, unless you use a certain SFP.

It's strange that one end shows the interface as up, but the other does not.
Is it possible that you're using SFPs that only do 1000base-T?
What if you take the individual ports out of the ae / etherchannel and just
go point-to-point,

Will JunOS show the ae as down, then?
[channel-group N mode on] with IOS just enables portchanneling unconditionally.
Wouldn't that, in conjunction wit
