- IP TOS. This is an optional configuration. The IP ToS field in a packet is defined
as all 8 bits of the service type octet in the IP header. The ToS bits value is a
hexadecimal number that is composed of numbers 00 to 09 and AA to FF. The
ToS mask value is a hexadecimal number that is composed of numbers 00 to FF.
The ToS 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 for which bit 7 is set and is the most
significant value, for which bit 5 is set, and for which bit 1 is cleared, use a ToS
bits value of 0xA0 and a ToS mask of 0xFF.
