4.9.3 Ethernet Type Filtering
Ethernet Type Filtering is done according to the packets’ Ethernet type, also known as
Layer 3 filtering. As in the two previous sections, there is a maximum of 64 entries for packets’
specification. Enabling is simple (packets are set as disabled by default, Figure 4.27),
checking the packet’s Ethertype box (located to the left of it, first column). Ethertype
numbering usually starts with 0x, in which  corresponds to a hexadecimal
number, e.g., 0xF0F0 which is to filter NETBUI type messages or 0x8035 for RARP type
messages; Figure 4.27.
