The first line of the debug shows an SNMP request from an SNMP agent
(server). In this request, you see the MIB objects that the SNMP agent wants
to get values for. The following lines show all MIB objects and their corre-
sponding values. In this case, some of the MIB objects are the System Uptime
and IP Address Entries. You can see that each MIB has a value assigned to
it. We finish by looking at the line that confirms that the MIB object values
were sent to the requesting machine.
Here is the debug:
