last minute prep question (and jitters) on how a router switches traffic. setting for the cit tomorrow. attempting to confirm my understanding of which type of switching is default for ip and which type for ipx, appletalk, etc.
from ciscopress "cisco internetwork troubleshooting" by chappell and farkas chapter 3 page 156 states that fast switching is the default switching mechanism for all protocols except ip. page 157 states that optimium switching is the default switching mechanism for tcp/ip traffic. question 3.5 at the end of the chapter asks "what is the default switching mechanism for ip traffic" and the given answer is "fast switching is the default switching mechanism for ip traffic" which is contradictory. the cisco site docs state optimum switching for ip and it makes sense given the underlying data structures (trie). then i run into the following question from a subscription service which runs counter to the whole lot "You have enabled priority queuing, custom queuing, or weighted fair queuing. Which traffic will always be classified by fast-switching logic? A - IP B - IPX C - AppleTalk D - DecNet Correct Answer - A IP traffic will always be classified by fast-switching logic. All other traffic will be process switched. Process switching means to find a route. Fast-switching logic puts the traffic in a cache." i'm guessing their talking about older versions of ios prior to optimum switching. arg, head hurts ..... thanks.
