Details of the hostTable are shown in Trace 7.10b. Note that the GetRequest (Frame 1), which was issued by the network management application, asks for the values of all objects within the hostTable, plus the value of the sysUpTime object {1.3.6.1.2.1.1.3.0}. The GetNext response (Frame 2) returns the values of these objects (note that in the first ten object names in the following table, the prefix “host” has been deleted for brevity):


Address Creation Order Index InPkt Out Pkts In Octets Out Octets Out Errors Out Broadcast Pkt Out Multicast Pkts sys Up Time
F1A1E01F 12 20480 493 710 192789 67601 0 40 0 798171

Note from Trace 7.10b that the index given for each object (20480.6.126.241.XXX.YYY.48.31) is selected by the Console and includes the IP address of the workstation that initiated the request (XXX.YYY.48.31). Also note that the value of the sysUpTime object provides a timestamp for the data in this entry.

Frames 3–32 retrieve the values of the matrixSDTable, with the retrieval of the first row illustrated in Frames 3–4, the second row in Frames 5–6, the third row in Frames 7–8, and so on, as shown in Trace 7.10c. (As in the previous example, the term “matrix” is deleted from each of the first six object names shown in the column headings for brevity). Notice the change in the values of the sysUpTime object at each table entry:
