SUMMARY
When the SNMP agent receives a request for multiple variables in a single packet, for each entry in the variable bindings list the agent queries the required sub-agent (in this case, the .DLL acting as the agent) and packs up the results in a response variable bindings list and returns it in a single packet.

For example, say the variables requested are:

  ip.ipInReceives            (Internet MIB II ) tcp.tcpMaxConn           (Internet MIB II )   .iso.org.dod.internet.private.enterprises.lanmanager.lanmgr-2.common. comVersionMaj           (LanManager MIB II)   icmp.icmpOutErrors         (Internet MIB II ) In this case, the agent queries the INETMIB2.DLL file twice, the LMMIB2.DLL once, and the INETMIB2.DLL once. Then it packs the results in a response packet and sends it to the requesting manager. There is no "snapshot" of the MIB.

STATUS
This problem was corrected in Windows NT version 4.0.
