LARTC - Dec 2004 - FW: differing rate and ceil values

Hello all, when running tc -s -d class show dev eth, the parent class rate
and ceil are different to the configuration?
his is the first time I have used HTB so I may have made some basic
mistakes.
 
Thanks in advance
 
Shaun

If you do the math, 760/95 = 8

There are 8 bits in a byte.

Does that clarify it for you?
