The DC command prints a full data communications analysis.
Syntax
── DC ─┬───────────────┬───────────────────────────────────────────────┤
└─ NSP ─┬───────┤
└─ MSG ─┘Explanation
The following text describes the meaning of each option.
DC
Prints a full data communications analysis.
DC NSP
In addition to a full data communications analysis, prints an analysis of the network support processor (NSP) tables. This analysis includes NSP line vectors, NSP line tables, and NSP station tables in addition to the data communications controller (DCC) table analysis.
DC NSP MSG
In addition to a full data communications analysis, analyzes messages in nontanked data comm queues in the DCALGOL queue.
Example
The following example shows output from the DC command.
INPUT: DC NSP MSG
