nettl(1M) nettl(1M)
pduout Outbound Protocol Data Unit (including header and data).
proc Procedure entry and exit.
state Protocol or connection states.
error Invalid events or condition.
logging Special kind of trace that contains a log message.
loopback Packets whose source and destination system is the same.
For multiple kinds, the masks can be specified separately or combined into a single
number. For example, to enable both
pduin and pduout (to trace all packets coming
into and out of the node) use either
pduin pduout or 0x10000000 0x20000000
or the combination 0x30000000 .
Not all subsystems support all trace kinds. No error is returned if a given subsystem does
not support a particular trace kind.
For example, the following NS_LS_* subsystems support only the
pduin and pduout
trace kinds: NS_LS_TCP, NS_LS_UDP, NS_LS_IGMP, NS_LS_ICMP, NS_LS_IP,
NS_LS_IPV6 and NS_LS_ICMPV6.
If a -traceon is issued on a subsystem that is already being traced, the tracing mask and
optional values are changed to those specified by the new command, but the new -file
,
-size, and -tracemax options are ignored and a message is issued.
If -entity all is specified, all recognized subsystems are traced except X.25-specific
subsystems. To turn on tracing for X.25, use the command
nettl -traceon kind -e x.25_subsys -card dev_name
where the value of x.25_subsys is SX25L2 or SX25L3.
-setfilter filter_file
(Abbr.: -sfl)
Used as a standalone option.
This command is used to set filter expressions for subsystems. The filter expressions are
specified in the filter configuration file filter_file. Currently filters are supported for the fol-
lowing subsystems: GELAN, IGELAN, BTLAN, INTL100, IETHER, IXGBE, NS_LS_IP,
NS_LS_TCP, NS_LS_UDP, and NS_LS_ICMP. The syntax for the filter configuration file is
given below.
-filteron all
-filteron
subsystem ...
(Abbr.: -flon)
Used as a standalone option.
Used to turn on a filter that has been set with the setfilter option for the subsystem.
This makes the filter active. If the attribute
all is specified then filters are turned on for
all the subsystems that currently support filters as listed above.
-filteroff all
-filteroff
subsystem ...
(Abbr.: -floff)
Used as a standalone option.
Used to turn off a filter that has been previously turned on with the filteron option for
the subsystem. This makes the filter inactive, but it is still set to be turned on in the
future. If the attribute all is specified then filters are removed for all the subsystems that
currently support filters as listed above.
-displayfilter all
-displayfilter
subsystem ...
(Abbr.: -dfl)
Used as a standalone option.
Used to display the filters and their respective states. If the filter is set or turned on for a
subsystem, the filter expression is displayed along with the status of the filter. If no filter is
set for a subsystem then the corresponding filter status is mentioned. If the attribute all
