Priority
– Bandwidth is the minimum guaranteed, but it is also the maximum limit
-> Above this limit, traffic will be dropped
Between priority and bandwidth, the format can be mixed
class VOICE
priority percent 60
class FTP
bandwidth 300
Remaining Percent
– e.g. – Voice -> 60% of bandwidth
FTP -> 30% of the remaining bandwidth
– Remaining bandwidth = Actual BW – (any priority bandwidth + class-default bandwidth)
– 200 – ( 1200 + 500 ) = 300 kbps
