LACP PDUs generated by lacpd on the i4x00 and i2x00 platforms contain the wrong Ethernet source MAC address.
Some Cisco and Juniper switches discard these PDUs. They send PDUs as if the BIG-IP system is not transmitting with an all-zeros 'Partner' section System ID. This renders LACP inoperable, and simply does nothing if the far end is configured for 'Passive'.
LACP configured on an trunk interface on i4x00 or i2x00 platforms.
The BIG-IP software now inserts the correct Source MAC address in the LACP PDU.
