• IP TOS - The IP TOS field in a packet is defined as all eight bits of the Service
Type octet in the IP header. The TOS Bits value is a hexadecimal number from 00

Mask denotes the bit positions in the TOS Bits value that are used for comparison
against the IP TOS field in a packet. For example, to check for an IP TOS value
having bits 7 and 5 set and bit 1 clear, where bit 7 is most significant, use a TOS
Bits value of 0xA0 and a TOS Mask of 0xFF. This is an optional configuration.
