BIG-IP Virtual Edition (VE) running on Amazon AWS does not support the jumbo frames with MTU set to 9001. A smaller MSS is suggested in TCP connection's 3-way handshake.
Jumbo frame requests are not honored by BIG-IP VE.
BIG-IP VE runs on some Amazon AWS instances with their NICs' MTU set to 9001 by default.
Manually set the NICs' MTU to 9001 after it has been fully started.
Set up a dataplane interface's MTU up to 9198 with this fix. To make a VLAN and the interface from which it derives have the new MTU, run the command: tmsh modify net vlan <vlan-name> mtu <mtu>.
