Configuring the Trunk Utilization Limit

The trunk utilization limit feature is introduced in Release 5. The purpose of this feature is to prevent
the grooming of connections to overloaded trunks.
Trunk utilization is the percentage of bandwidth is in use and is calculated by dividing the bandwidth in
use by the maximum bandwidth available. The trunk utilization limit defines a trunk usage level above
which grooming is denied for all connections that use trunks operating above the utilization limit. For
example, if the trunk utilization limit is set at 80 percent and a candidate connection for grooming tries
to use a target trunk operating at 85 percent usage, the candidate connection cannot be rerouted using
that target trunk.
