18.6 SNMP Management Information Bases
A managed object, sometimes called a MIB object, is one of many specific characteristics of a managed
device. The MIB consists of hierarchically organized object instances (variables) that are accessed by
network-management protocols such as SNMP.
18.6.1 IETF-Standard MIBs for the ONS 15454
Table 18-2 lists the IETF-standard MIBs implemented in the ONS 15454 SNMP agents.
First compile the MIBs in Table 18-2, then compile the MIBs in Table 18-3.
Caution If you do not compile MIBs in the correct order, one or more might not compile correctly.
Table 18-1 ONS 15454 SNMP Message Types
Operation Description
get-request Retrieves a value from a specific variable.
get-next-request Retrieves the value following the named variable; this operation is often used to
retrieve variables from within a table. With this operation, an SNMP manager does
not need to know the exact variable name. The SNMP manager searches
sequentially to find the needed variable from within the MIB.
get-response Replies to a get-request, get-next-request, get-bulk-request, or set-request sent by
an NMS.
get-bulk-request Fills the get-response with up to the max-repetition number of get-next interactions,
similar to a get-next-request.
set-request Provides remote network monitoring (RMON) MIB.
trap Indicates that an event has occurred. An unsolicited message is sent by an SNMP
agent to an SNMP manager.
