Zheng yi,
Traffic is allocated at the network level specified in the
access-list. Therefore, traffic from 1.1.1.1, 1.1.1.2, and 1.1.1.3
COMBINED can not exceed the preset limit. if the first user at 1.1.1.1
dominates the bandwidth, users at 1.1.1.2 and 1.1.1.3 get no bandwidth,
i.e., their packets are dropped.
HTH,
Les
