I been it on it since 4am. Still can't figure that one out ...
>From Cisco:
"After the token is claimed and changed to an information frame, only stations with
priority higher than the trasmitting station can reserve the token for the next pass
around the network. When the next token is generated, it includes the highest priority
of the reserving station. Stations that raise a token's priority level must reinstate
the previous lower priority level after their transmission is complete"
CASE SCENARIO:
I have 3 stations: A , B, and C Their resective priorities are 1 , 4, and 5. Station X
Y Z have priority 0
Station A grabs the token (the priority at the time was 0) and and put data on it.
While it goes around the ring, station B reserves the token for itself. When the token
comes back to station A (we assume X was the destination), A creates a new token with
priority 4 and no reservation set.
QUESTIONS:
Question: Is the last statement of my case scenario correct or is it the other way
arround? (A creates a new token ring with the previous priority: 0 and set the
reservation to 4).
