690 Configuring Port-Based Traffic Control
If Industry Standard Discovery Protocol (ISDP) is enabled on an interface, 
and the LLPF feature on an interface is enabled and configured to drop ISDP 
PDUs, the ISDP configuration overrides the LLPF configuration, and the 
ISDP PDUs are allowed on the interface.
