I am using QoS in my production network by applying IP Precedence. I have identified four classes. But when the link is congested in peak times, the lower two classes are completely dropped because the upper two eat the entire bandwidth.
Then i saw that i can fix bandwidth using the BANDWIDTH command in class-maps. But lets say if i allocate the bandwidth as 50%, 30%, 10%, 10% to all classes respectively. So, in congestion times the lower classes will still have some bandwidth to consume.
My question is, that when the link is not congested, will my top class still have only 50% of the bandwidth to use or it can use as much as it can get. I hope i have made my question clear.
Thanks in advance.
