Please i have a production network connected to the branch through tunnel over ISP cloud. My issue is the link is 128kbps, but the users over use the link amount to around 150kbps with exchange,and netbios taking most of the BW. What I want is I want the level of priority to be as follows. Http(s),mail and may be netbios e.t.c. Please give me a typical config template.

Don't know if there's "a typical config template". But using CBWFQ might match your requirements, assuming it's supported by your platform.


For an idea: (NB: syntax likely incorect)


class-map match-any HiPriority

match protocol http


class-map match-any MidPriority

match protocol exchange


class-map match-any LoPriority

match protocol netbios

match protocol ftp


policy-map SampleCBWFQ


class HiPrioity

bandwidth percent 25

class MidPrioity

bandwidth percent 5

class LoPrioity

bandwidth percent 1


interface serial 0

policy-map output SampleCBWFQ


You determine number of classes, what they comprise and their allocation of bandwidth.
