Managing Connection Grooming
Manually Grooming Connections
Manual grooming, which is also called on-demand grooming, grooms one or more port connections
immediately. You can groom a specific connection by specifying the port ID, VPI, and VCI, groom a
range of connections, or groom all connections on the port. To manually groom the connections on an
port, enter the optrte command as follows:
M8850_LA.7.PXM.a > optrte <portid> [-vpi <vpi>] [-vci <vci>] [-range
<starting-vpi/vci..ending-vpi/vci>]
Table 8-11 describes the optrte command parameters.
The following example grooms all connections on port 30.1:
M8850_LA.7.PXM.a > optrte 30.1
The next example grooms a single connection on port 30.1:
M8850_LA.7.PXM.a > optrte 30.1 -vpi 30 -vci 119
This example grooms all connections in the range of VPI/VCI 100/100 and VPI/VCI 200/200 on port
6:1.3:13:
M8850_LA.7.PXM.a > optrte 6:1.3:13 -range 100/100..200/200
Configuring the Grooming Thresholds
Cisco MGX Release 5 software introduces more options for determining when to reroute a connection
during grooming. Prior to Release 5, the only grooming threshold was cumulative administrative weight.
In Release 5, you can define percentage reduction values and absolute threshold gains for the following
traffic metrics:
• Administrative Weight (AW)
• Cell transfer delay (CTD)
• Cell delay variation (CDV)
Table 8-11 Parameters for optrte Command
Parameter Description
portid Root endpoint port identifier, in the format [shelf.]slot[:subslot].port[:subport]. To display
a list of the available ports, enter the dsppnports command.
vpi When the -vpi option is specified, the optrte command grooms only those port
connections that use the specified VPI. To display a list of connections that includes the
VPI and VCI for each connection, enter the dspcons command.
vci When the -vci option is specified, the optrte command grooms only those port
connections that use the specified VCI. To display a list of connections that includes the
VPI and VCI for each connection, enter the dspcons command.
-range When the -range option is specified, the optrte command grooms only those port
connections in the specified VPI and VCI range. Enter the range using the format:
starting-vpi/vci..ending-vpi/vci. You must enter two periods between the starting VPI/VCI
and the ending VPI/VCI. The slash character is required between the VPI and VCI in each
VPI/VCI pair.
