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. Config:
ge-0/0/11 < ether-options < 802.3ad ae11; >> ge-1/0/11 < ether-options < 802.3ad ae11; >> ae11 < aggregated-ether-options < lacp < passive; >> unit 0 < family ethernet-switching < port-mode access; vlan < members 10; >> > > . xe-0/1/0 < ether-options < 802.3ad ae48; >> xe-1/1/0 < ether-options < 802.3ad ae48; >> ae48 < enable; aggregated-ether-options < lacp < passive; >> unit 0 < family ethernet-switching < port-mode trunk; vlan < members [ 10 230 1001-1002 1600 2551 ]; >> > >
