Prints link status information, or activates or deactivates
link level tracing on the specified data communications
line. Node Manager (NM) capability is required.

"LINKNAME" is a required parameter. The STATUS parameter value
can be specified by preceding it with a comma or semicolon. If
the STATUS parameter is preceded by a semicolon, it is assigned a
keyword value and must be entered as "STATUS=". TRACE must be
specified as a keyword, preceded by a semicolon and entered as
"TRACE=". Either STATUS or TRACE may be specified, but not both.
If neither STATUS or TRACE is specified, the default is STATUS.
LINKNAME= Specifies the name of an active data communications
link.
@ Specifies all active data communications links.
Other wildcard characters are not allowed.
linkname The name of an active data communications link. This
is the name that was configured for that link by
NMMGR in the datacomm configuration file.
STATUS= Requests status information about the link. This
is the default option. If @ is specified for the
linkname, then the default for STATUS= will be
LINKSTATE; otherwise STATUS=ALL is assumed.
ALL Prints configuration information followed by
link statistics information.
LINKSTATE Prints link name, link type, and link state
information.
CONFIGURATION Prints LINKSTATE information and configuration
information.
STATISTICS Prints LINKSTATE information and various link
statistics, including some accumulated link level
error statistics.
DIAGSTATS Prints LINKSTATE information, followed by link
statistics, which include diagnostic statistics.
RESET Prints LINKSTATE and statistics, then resets
accumulated link statistics counters to 0.
TRACE= Requests trace options for the link. May not be
specified at the same time as STATUS.
ON or OFF Turns link level trace on or off. Either ON or OFF
must be specified. If OFF is specified, the syntax
of any following subparameters is checked, but these
parameters are ignored.
DATA or ALL Used ONLY for LAN links.
Specifies the type of data to be traced. DATA
means trace all read and write requests. ALL means
trace all read, write, control, status, and
exception requests. If neither DATA or ALL is
specified DATA is the default.
PARTIAL or FULL Used ONLY for LAP-B or SDLC links.
Specifies the type of data to be traced. PARTIAL
means all read, write, control, status, and
exception requests are traced. Only the first 16
bytes of data are traced for reads or writes. FULL
means that all read, write, control, status,
exception requests, and the entire data field are
traced. If neither FULL or PARTIAL is specified,
PARTIAL is the default.
buffsize Size in Kbytes of the trace buffer area in memory.
This area is used to buffer trace data before it can
be written to disk. Allowable values are 1 to 16.
The default is 4 for LAN links, and 5 for LAP-B and
SDLC.
tracefilename Designates the name of the disk file where the
trace data is written. If tracefilename is not
specified, a file with the name NMTCnnnn.PUB.SYS
will be supplied automatically, where nnnn varies
from 0 to 9999. If a filename is specified without
group or account names, the current group and
account names of this user are used.
LINKCONTROL STATUS prints configuration and link level statistics
information about the specified active link. LINKCONTROL TRACE
manages link level tracing for the specified link. Either
LINKCONTROL STATUS or LINKCONTROL TRACE may be specified, but not
both.
LINKCONTROL @ {STATUS=LINKSTATE is default}
LINKCONTROL @;STATUS=ALL {STATUS=ALL for all }
or { active links }
LINKCONTROL @,ALL
LINKCONTROL DTSLINK;STATUS=ALL {STATUS is keyworded}
LINKCONTROL LAPBLINK {STATUS=ALL is default}
LINKCONTROL SYSLINK,RESET {STATUS=RESET}
LINKCONTROL SYSLINK;TRACE=ON,DATA,8 {TRACE is keyworded}
LINKCONTROL SYSLINK;TRACE=OFF
