show the bandwidth in use at each priority level in the transmit and receive directions, respectively. The
# of Conns column shows the number of logical connection numbers reserved at each priority level.
Managing Connection Grooming
Connection grooming is the process of checking each connection to determine if a more efficient route
is available. If a prospective new route is significantly better than the incumbent route, the connection is
rerouted.
The Cisco MGX Release 5 software provides many features for implementing and managing connection
grooming. The following sections describe these connection grooming topics:
