[j-nsp] M-20 to 3750 LACP config

[Patrick Coppinger]

I've seen a few posts on this topic, and believe I have followed the 
example closely, but both my port-channel interface (Down/Down) and ae0 
interface (Up/Down) won't come up, even though the physical interfaces are 
all Up/Up. Any tips would be appreciated.

chassis {
     aggregated-devices {
         ethernet {
             device-count 1;
         }
     }
}
interfaces {
     ge-0/2/0 {
         gigether-options {
             802.3ad ae0;
         }
     }
     ge-0/3/0 {
         gigether-options {
             802.3ad ae0;
         }
     }
     ae0 {
         aggregated-ether-options {
             no-flow-control;
             link-speed 1g;
             lacp {
                 active;
             }
         }
     }
}
