SNAX/CNM Manual

SECTION 1
INTRODUCTION
This manual discusses the programmatic interface to the SNAX
Service Manager ($SSCP) that allows a program running in a Tandem
system to perform network-management functions. The program can
serve as both of the following:
• A Communications Network Management Application (CNMA). In
this role, the program can use CNM verbs to request configura-
tion and statistical information maintained by $SSCP and can
request operational statistics from physical devices. Within
these verbs, the program has the option of embedding either a
REQMS (Request for Maintenance Statistics) record or an NMVT
(Network Management Vector Transport) that requests network
information. The application can accept either:
-- solicited or unsolicited RECFMS (Record Formatted
Maintenance Statistics), or
-- solicited or unsolicted NMVTs that contain network
information.
• A Communications Network Management Server (CNMS). In this
role, the program accepts from an SNA host either a REQMS
record or an NMVT requesting network information; it replies
with a RECFMS or with an NMVT containing network information
after it has temporarily assumed the CNMA role needed to
gather the requested data.
