EFP-filter - Ethernet Flow Point Filter.
It is possible to transmit a packet out a subinterface with VLAN tags that are not compatible with that subinterface. In other words, if that packet arrived on the output port, it would not be classified as coming from the output subinterface. This can happen in various ways: through misconfiguration, by putting subinterfaces with different VLAN encaps in the same bridge-domain, etc. The EFP Filter Check detects such packets and drops them. It consists of two checks, one that verifies the packet prior to output VLAN tag rewrite and one that verifies the packet after VLAN tag rewrite.
