A trunk configured between a BIG-IP i4x00/i2x00 platform and an upstream switch may go down due to the presence of the VLAN tag.
Trunks are brought down by upstream switch.
LACP configured between a BIG-IP i4x00/i2x00 platform and an upstream switch.
There are two workarounds: -- Configure the trunk as 'untagged' in one of the VLANs in which it's configured. -- Disable LACP.
The system no longer transmits a VLAN tag for LACP PDUs, so this issue no longer occurs.
