Enabling And Disabling Soft Rerouting For Grooming; Configuring Scheduled Grooming - Cisco MGX 8850 (PXM1E/PXM45) Configuration Manual

Chapter 8 Managing PNNI Nodes and PNNI Routing
Softrerouting is disabled by default. For soft rerouting to work properly, you must enable soft rerouting
and the nodes that host the master and slave endpoints must run Cisco MGX software Release 5 or later.
The first time a connection is rerouted, the master endpoint queries the slave endpoint to determine if it
supports soft rerouting. The first reroute is a hard reroute, but if the master learned that the slave supports
soft reroute, all future reroutes are soft reroutes. If either the master endpoint or the slave endpoint do
not support soft rerouting, all grooming for that connection used the hard reroute method.
Note Cisco MGX switches use soft rerouting for grooming P2P connections. P2MP connections cannot be
groomed.

Enabling and Disabling Soft Rerouting for Grooming

Soft rerouting is described in the previous section,
or disable soft rerouting for connection grooming, enter the cnfndrteopt command as follows:
M8850_LA.7.PXM.a > cnfndrteopt [-softreroute enable | disable]
To enable soft rerouting, include the -softreroute enable option. To disable soft rerouting, specify
-softreroute disable.
The cnfndrteopt command configures other features that are described later in this chapter.
Note
describes the other cnfndrteopt command parameters.
The following example enables soft rerouting and uses the dspndrteopt command to verify the
configuration change:
PXM1E_SJ.7.PXM.a > cnfndrteopt -softreroute enable
PXM1E_SJ.7.PXM.a > dspndrteopt

Configuring Scheduled Grooming

Scheduled grooming automatically grooms one or more port connections at specific times. 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 automatically groom the port connections at specified times, enter
the cnfrteopt command as follows:
M8850_LA.7.PXM.a > cnfrteopt <portid> <flag> [-range <starting-vpi/vci..ending-vpi/vci>]
[-interval (range=10..10000) (default=60)] [-tod <time-of-day>] [-weekday <day-of-week>]
Table 8-10
Release 5.0.10, OL-3845-01 Rev. B0, August 16, 2004
describes the cnfrteopt command parameters.
