One more question for the day.
I have just been asked to limit a switch port to a max rate of 2,000,000.
SO I think, right, this is not so bad.
I try the following Police, and unicast supression, cant use CAR or TS on
3550 so it looks) with the following results :- when sending a 5MB stream
from an attached PC.
Any ideas? - Sorry, its my second post today :) QoS day!
