A.7 Tracing Options
Table A–5 (Cont.) Protocol Significance Options
Option Description
normal Traces normal protocol occurrences. Abnormal protocol
occurrences are always traced.
policy Traces the application of protocol and user-specified policy to
routes being imported and exported.
task Traces system interface and processing associated with this
protocol or peer.
timer Traces timer usage by this protocol or peer.
route Traces routing table changes for routes installed by this
protocol or peer.
Note
Not all of these options apply to all of the protocols. In some cases, their
use does not make sense (for instance, RIP does not have a state machine)
and in some instances the requested tracing has not been implemented
(such as RIP support of the policy option).
It is not possible to specify packet tracing from the command line because
a global option for packet tracing would potentially create too much
output.
When protocols inherit their tracing options from the global tracing options,
tracing levels that do not make sense (such as parse , adv , and packet tracing
options) are masked out.
Global tracing statements have an immediate effect, especially parsing options
that affect the parsing of the configuration file. Tracing values inherited by
protocols specified in the configuration file are initially inherited from the global
options in effect as they are parsed, unless they are overridden by more specific
options.
After the configuration file is read, tracing options that were not explicitly
specified are inherited from the global options in effect at the end of the
configuration file.
A.7.2 Packet Tracing
Every protocol has one or more options for tracing packets. All protocols allow
the packets keyword to be used for tracing all packets sent and received by the
protocol. Most protocols have other options for limiting tracing to a useful subset
of packet types. These tracing options can be further controlled with the following
modifiers:
detail Specifies a more verbose format to provide more information
about the contents of the packet. The
detail option must be
specified before
send or recv . By default, packets are traced
in a terse form of one or two lines.
send Limits the tracing to packets sent received. If neither the send
nor the recv option is specified, both sent and received packets
are traced.
