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

[Patrick Coppinger]

Thanks to everyone who responded. I had to do a couple of things, seperate 
people had suggested to get it working on my hardware. One was to make the 
Juniper side passive and the Cisco side active. No other combination seemed 
to work. Also, I had to add a unit 0 to the Juniper in order for it's ae0 
interface to come up/up. Below is a working configuration example. Thanks!

interface Port-channel1
  no ip address
!
interface GigabitEthernet1/0/27
  no ip address
  channel-group 1 mode active
!
interface GigabitEthernet1/0/28
  no ip address
  channel-group 1 mode active


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 {
                 passive;
             }
         }
         unit 0;
     }
}
