Can you try to create a vlan for analyzer (output)..
and map the ae part of that output vlan.
SOmething like this.
To mirror traffic that is traversing interfaces or a VLAN on the switch to a VLAN for analysis from a remote location:
Configure a VLAN to carry the mirrored traffic. This VLAN is called remote-analyzer and given the ID of 999 by convention in this KB:
[edit]
user@switch#set vlans remote-analyzer vlan-i
d 999
Set the uplink module interface that is connected to the distribution switch to trunk mode and associate it with the remote-analyzer VLAN:
[edit]
user@switch#set interfaces ae0 unit 0 family ethernet-switching port-mode trunk vlan members 999
user@switch# set interfaces ge-0/1/1 ether-options 802.3ad ae0
user@switch# set interfaces ge-0/1/2 ether-options 802.3ad ae0
Specify the traffic to be mirrored- in this example the packets entering ports ge-0/0/0 and ge–0/0/1:
[edit ethernet-switching-options]
user@switch#set analyzer employee-monitor input ingress interface ge-0/0/0.0
user@switch#set analyzer employee-monitor input ingress interface ge-0/0/1.0
Specify the remote-analyzer VLAN as the output for the analyzer:
[edit ethernet-switching-options]
user@switch#set analyzer employee-monitor output vlan 999
