There are two basic options here.
a) You can design your MIB tables to include an index which
specifies which device to query.
This has the advantage that you can query several devices in a
single request, but does require that you have control over the MIB
definitions (and can change them)
b) You can use the SNMPv3 "context" field to specify which
device to query. (And the SNMPv1/2c community string can
be used in the same way).
This is a little more complex to set up, and you can only query one
device at a time. But it doesn't affect the MIB definitions, which
may be an issue if you're working with existing MIBs.
