Re: Remaining Percent??

Let's say your bandwidth is 256K and you have NOT touched the max-reserve
command under the interface,
the following will be the difference:

With "bandwidth percent 50" command you will get:

100 percent of 256 is taken first which means 256K
Then 50 percent of 256K which is 128K is what you are assigning

With "bandwidth percent remaining 50" command you will get:

75 percent of 256 is calculated first which means 192K
Then 50 percent of 192K which is what you are assigning, which is 96

I hope this helps
