[j-nsp] 3750 and 4200

[Eric Krichbaum]

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.

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 two sides of links are working together.

Will JunOS show the ae as down, then?

[channel-group N mode on] with IOS just enables portchanneling
unconditionally.
Wouldn't that, in conjunction with a JunOS without an "lacp" stanza
under the ifd / interface stanza (lacp passive) work just fine? I've
mostly only been doing JunOS-JunOS LACP lately, though I've done it
quite a bit with Cisco-Cisco in the past.

LACP is worth running on your links if it works, IMO.

Maybe try setting active on the JunOS and Cisco sides?

!
interface Fa1/0/9
channel-group 10 mode active

set interface ae1 aggregated-ether-options lacp active
