Guys

Can someone clarify this for me .

These are the 5 Major commands used in QOS and my explanations for them .

RATE-LIMIT - Old NON-MQC version of police .IN and OUT , cant use policy
maps , uses ACL to match traffic

POLICE - In and Out , uses MQC , can use policy-maps ,

SHAPE , reserves bandwidth for class and buffers excess, uses MQC

PRIORITY, Gives priority access to the hardware buffer for a certain amount
of traffic , drops excess. Uses MQC

BANDWIDTH - allocates fixed amount of guaranteed bandwidth , best effort for
excess traffic ( excess gets put with everyone else, or dropped) uses MQC.

I know these are Rough answers , but to me they are pretty much the
difference between the commands .

Please feel free to expand on them .

Many thanks in advance
