Tracing Established Connections
Modifying SPVC Priority Routing Configuration
Enter the cnfcon command and use the -rtngprio option to change an SPVC’s routing priority, as shown
in the following example:
pop20one.10.AXSM.a > cnfcon 3 101 101 -rtngprio 6
Tracing Established Connections
Release 3 of the MGX switches supports a path and connection trace feature which allows you to view
details about established connections and their paths on your network. This feature provides valuable
information for monitoring and troubleshooting your network.
• The highest range: the highest range is what is left over after you specify the lowest range, the
number of bandwidth groups, and the number of cells per second in each bandwidth increment.
• All incremental ranges between the lowest and the highest.
Note The derouting of SVCs uses the same priority routing criteria.
Before you can prioritize a specific SPVC, you must set up the priority routing feature on the node itself,
as described in the section that follows.
Setting and Viewing the Path Trace Feature on the Node
The Path trace feature is enabled on the switch by default. To disable path trace feature at the node level,
enter the pathtracenode disable command at the active PXM45, as shown in the following example:
popeye2.7.PXM.a > pathtracenode disable
To enable the path trace feature at the node level after it has been disabled, enter the
pathtracenode enable command at the active PXM45, as showing in the following example:
popeye2.7.PXM.a > pathtracenode enable
To view the current setting of the nodal path trace, enter the dsppathtracenode enable command at the
active PXM45, as showing in the following example:
popeye2.7.PXM.a > dsppathtracenode
dsppathtracenode: enable (1)
Setting and Viewing the Path Trace Feature on a Port
To enable or disable path trace feature at port level, enter the pathtraceport <portid> <options>
command. The result of a path trace is saved in a log file.
pathtraceport <portid> {enable|disable} [-H {on | off}] [-CB {on | off}] [-V {on | off}]
[-CR {on | off}] [-cldnum called-AESA] [-clgnum calling-AESA]
Table 7-37 describes the pathtraceport command options.
