BW guarantee without CBQ

Hi Group,

In IEWB Lab14, the QoS sections asks for half of the outgoing iface
bandwidth to be guaranteed for the traffic comming for a single host. The
requirment doesn't allow for CBQ to be used (no policy-map command allowed_
and the IE solution uses custom-queue-list, which is fair enough.

I was wondering for other ways for achieving the same effect, just in case
;)

One way, assuming that the interface bandwidth is known (T1) and that
``guaranteed`` means ``at least`` but not ``upto``, for which i can think
of:

int serial 0/0/0
 rate-limit output access-group 101 768000 144000 288000 conform-action
transmit exceed-action continue
 rate-limit..... <-other classes of traffic or none

access-list 101 permit tcp host 1.1.1.1 any <---the class of traffic to be
guaranteed 1/2 iface BW

Any other ideas of how this could be achieved appreciated!
Rado
