To use this solution:

Copy the SNMP.NLM to the server's SYS:\SYSTEM folder and copy SNMP.MSG to the server's SYS:\SYSTEM\NLS\4 folder.
Restart the server.

Note: It is mandatory that NetWare Server has to be restarted after applying this TID as snmp.nlm changes will come to effect only after restarting the server.

About the Fix: Agent displaying the sparse table behavior will respond with following response on encountering the sparse entry(or hole),

AttrValue->avb_info = (AttrInfo *)NULL
AttrValue->avb_length = SNMP_ERR_UNPOPULATEDCELL

Return SNMP_ERR_SPARSETABLEROW_UNPOPULATEDENTRIESMARKED as snmp errorcode

refer "Understanding SNMP MIBs" by David Perkins-Evan McGinnis for explanation on sparse table behavior

#define SNMP_ERR_SPARSETABLEROW_UNPOPULATEDENTRIESMARKED 100
#define SNMP_ERR_UNPOPULATEDCELL 101

SNMP switches its traditional behavior on getting the above response to special behavior to accommadate the sparse entries.
