On server side (PE1) to make LAG down you can unconfigure the channel-group 1 configurations and verify force-up is getting enabled in PE2.
To simulate the force-up
PE1(config)#interface ge44 | Enter interface mode. |
PE1(config-if)#no channel-group | Removing channel-group configurations from interface. |
PE1(config)#interface ge45 | Enter interface mode. |
PE1(config-if)#no channel-group | Removing channel-group configurations from interface. |
