SNMP Management Information Bases
12.5 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.
12.5.1 IETF-Standard MIBs for the ONS 15310-MA SDH
Table 12-2 lists the IETF standard MIBs implemented in the ONS 15310-MA SDH SNMP agent. You
must first compile the MIBs inTable 12-2. Compile the MIBS in Table 12-3 next.
Caution If you do not compile MIBs the correct order, one or more might not compile correctly.
Table 12-1 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.
