MIB syntax validation involves validating the private MIBs
with respect to SMI standards / ASN.1 rules. The reference
standards include RFC 2578, 2579, and 2580. SNMP Agent Tester
has defined parsing levels for checking the MIB syntax, viz.
Lenient, Normal, Serious, and Critical.
SNMP Agent Tester, based on the parsing level, performs various
checks with reference to the standards, validates the syntax,
and provides a report of failed test cases.
