SNMPHOST
Starting with the first entry in the hrDevice Table, SNMPHOST retrieves information
from as many hrDeviceTable entries as you request at invocation. When the entry is for
a processor, printer, or disk storage device, SNMPHOST also retrieves an additional
value from the tables indicated in Figure 2-3
. Table 2-5 provides some information
about the MIB objects retrieved.
