Juniper EX LACP over WiFi for Point to Point WiFi

Hi Gurus,

Need to ask your opinion for some ex LACP.

We have a customer using 2 pair of Ubiquiti p2p WiFi, and they want to LACP to ex switch.

I done configuration the LACP at both ex d.

However when I plug it the cable from the poe injector to the LACP members port. The link status remain in down state even admin status is up.

Configuration template that I used was below. I did not see any issues with the configuration. But however the interface link status just wont fire up. I did the same for Site A EX and Site B EX as well.

set chassis aggregated-devices ethernet device-count 10

set interfaces ge-0/0/43 description PowerBridge-Link-1
set interfaces ge-0/0/43 ether-options 802.3ad ae3

set interfaces ge-0/0/45 description PowerBridge-Link-2
set interfaces ge-0/0/45 ether-options 802.3ad ae3

set interfaces ae3 mtu 9216
set interfaces ae3 aggregated-ether-options link-speed 1g
set interfaces ae3 aggregated-ether-options lacp active
set interfaces ae3 aggregated-ether-options lacp periodic slow
set interfaces ae3 unit 0 family ethernet-switching port-mode access
set interfaces ae3 unit 0 family ethernet-switching vlan members 22
