Prints link status information, or activates or deactivates link level tracing on the specified data communications line. Node Manager (NM) capability is required.
LINKCONTROL [LINKNAME=] { @ } {linkname } [{;STATUS=} {A[LL]} ] [{ , } {L[INK[STATE]]} ] [ {C[ONF[IGURATION]]} ] [ {S[TAT[ISTICS]]} ] [ {D[IAG[STATS]]} ] [ {R[ESET]} ] [ ] [{;TRACE= } {ON } [,DATA] [,buffsize] ,tracefilename]] [ {OFF} [,ALL] ] [ [,PARTIAL] ] [ [,FULL] ] "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.
