If the 1841 is running a later IOS image that supports CBWFQ, you could do it as follows:


pseudo-config


class-map FTP

match protocol ftp


policy-map CBWFQ

class FTP

bandwidth 1mb

police 1mb


int s0

service-policy out CBWFQ


I'm suggesting using CBWFQ, which will allow you to easily expand QoS if you so desire.


You could also do the above with a shape command instead of police. The policier will drop all FTP traffic above 1 Mb, a shaper will queue it and to keep FTP from exceeding 1 Mb.


You could also not limit FTP bandwidth, but just prioritize to only use excess bandwidth.


e.g.


policy-map CBWFQ

class FTP

bandwidth percent 1
