Hello,
Solies' book v.II, pag 467, says: "You can change the amount of bandwidth available for CBWFQ.". It says it is possible to configure up to 75% by default.
Studying this point I though it would be impossible to configure 4 class under policy map in the way the sum of the bandwidth was 80%. But when configuring, the router does not complain:
r1#sh policy-map interface ser 0/0 output
Serial0/0

Them I read http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fqos_r/qrfcmd1.htm#1029500
and it says you can configure up to 100%.
Is there a mistake on Solies' Book?
