Managing Connection Grooming
The following example sets the percentage reduction and absolute threshold for CBR connections that
reroute based on cumulative AW. This example uses the dsprteoptcnf command to show the change in
grooming threshold parameter values.

Configuring Orderly Grooming
Orderly grooming is introduced in Cisco MGX Release 5 software. Orderly grooming completes the
reroute of a batch of connections before attempting to groom the next batch. In earlier software releases,
the grooming process would analyze and release multiple connections, regardless of the number of
connections that were waiting rerouting. With orderly grooming, a configured number of connections
are released. When the batch of released connections are rerouted, the next batch of connections is
analyzed. The default batch size for grooming is 1 connection, but the batch size can be configured for
up to 1000 connections.
Orderly grooming is disabled by default. After you enable orderly grooming, all manual and scheduled
grooming operations use orderly grooming. To enable and configure orderly grooming, enter the
cnfndrteopt command as follows:
M8850_LA.7.PXM.a >
cnfndrteopt
[-og enable | disable] [-ogbatchsz
size
]
[-ogtimeout
timeout
]
describes the cnfndrteopt command parameters.
