What is the difference between DSCP 1 and precedence 1? Does it match different traffic patterns?

The question specifies Telnet traffic with IP Precedence bit set to 1. In my solution, I configured as follows class-map match-all TELNET-PREC1 match protocol telnet match ip precedence 1 vs. Yusuf's solution, which is class-map match-all drop23 match protocol telnet match ip dscp 1 His second match statement is matching on the DSCP value, whereas the question specifies IP Precedence. Is this a mistake on his part or does it come to the same thing - and if so then how ? Thanks again Mark
