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.
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.
