Changes in SNAplus2 Functions in R6.0 and later releases
RTM Statistics
Chapter 458
RTM Statistics
SNAplus sent RTM statistics to Netview using unsolicited NMVTs. This
behavior is outside the official IBM architecture and has been corrected
in SNAplus2 R.5, R.6 and later releases.
In general, SNAPlus2 will only send RTM statistics if explicitly
requested by Netview (i.e. in response to a request for statistics). To
allow SNAplus2 to send unsolicited RTM statistics, Netview must send a
RTM Control NMVT requesting unsolicited RTM data.
