I'm new to Juniper products and I bough two older EX4200-48t. I setup virtual chassis and add a few LAGs with LACP. All LAGs on copper connections works fine but on the 10GB module not. The module is part number 740-021309 (10GBASE-LR 10km 1310nm 70C). ae11 is an LAG with LACP and two 1G copper uplinks and ae48 is the LAG with the two SPF+ modules. Both LAGs are connected to the provider switch. I don't know which switch they are using. They only told me, that LACP is in active mode and the don't know why there is a problem.

ge-0/0/11 {
ether-options {
802.3ad ae11;

Edit 1:
When I disable LACP on ae48 then I can see incoming LACP packages on both interfaces with command "monitor traffic interface xe-0/1/0"
When I activate LACP passive again first I see no traffic and after a while one interface receive sometimes (about every 1 minute and 40 seconds) a LACP package.
