SNA network monitoring NMI: Enabling and disabling the interface

You can enable the SNA Network Monitoring data interface by setting the VTAM® start option SNAMGMT to YES, and you can disable the interface by setting the VTAM start option SNAMGMT to NO. The default for this start option is NO, and the start option is modifiable after VTAM is started. This start option can be specified in any of the following ways:

Using the START command for VTAM
1. IBM® default value is NO
2. Within the default VTAM start option list ATCSTR00 (ATCSTR00 is always used regardless of whether LIST=xx was entered to specify a supplemental VTAM start option list)
3. Within the supplemental VTAM start list (ATCSTRxx, if LIST=xx entered) as SNAMGMT=YES or SNAMGMT=NO
4. From the backup start option list (specified by the LISTBKUP start option)
5. START command options entered by operator as SNAMGMT=YES or SNAMGMT=NO
6. START command options reentered by the operator
See Sources of start options in z/OS Communications Server: SNA Network Implementation Guide for more information.
Using the MODIFY VTAMOPTS command
- MODIFY vtamprocname,VTAMOPTS,SNAMGMT=YES
- MODIFY vtamprocname,VTAMOPTS,SNAMGMT=NO

The current value of the SNAMGMT start option is displayable using any of the following VTAM DISPLAY commands:

DISPLAY NET,VTAMOPTS
DISPLAY NET,VTAMOPTS,OPTION=SNAMGMT
DISPLAY NET,VTAMOPTS,FUNCTION=VTAMINIT
