The -tn and -6tn command line parameters
The -tn parameter specifies the external tracing level
for OMPROUTE initialization and IPv4 routing protocols, where n is
a supported trace level. The -6tn parameter specifies the
external tracing level for IPv6 routing protocols, where n is
a supported trace level. The -tn and -6tn traces
are intended for customers, testers, service, or developers, and provide
information on the operation of the routing application. These options
can be used for many purposes, such as debugging a configuration,
education on the operation of the routing application, verification
of test cases, and so on. The following levels are supported:
- 1
- Informational messages
- 2
- Formatted packet trace
These option levels are cumulative—level 2 includes level 1. For example, -t2 provides formatted packet trace and informational messages.
