[j-nsp] 3750 and 4200

[snort bsd]

thanks all for replies. both ends (physical are up now, with no lacp. as simple as just rebooted cisco switch.

really lacp isn't my concern at this moment.

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?

set interface ae1 aggregated-ether-options lacp active
