You have two packets with decimal ToS values of 32 and 34. What are their results, respectively, in an IP precedence-only device?
-
Both packets have an IP precedence tag of CS4, and the packet with the decimal value of 34 has a higher drop probability.
-
The packet with the decimal value of 32 has an IP precedence tag of CS4, while the other decimal value of 34 is ignored and treated as best effort.
-
