SNMP Network Management Platforms

The SNMP manager uses information in the MIB to perform the operations described in Table 4-1.

Figure 4-1 SNMP Network

Table 4-1 SNMP Operations

Operation Description

get-request Retrieves a value from a specific variable.

get-next-request Retrieves a value from a variable within a table.

1. With this operation, an SNMP manager does not need to know the exact variable name. A sequential search is performed to

find the needed variable from within a table.

get-bulk-request

2. The get-bulk command only works with SNMP version 2.

Retrieves large blocks of data, such as multiple rows in a table, which would

otherwise require the transmission of many small blocks of data.

get-response Replies to a get-request, get-next-request, and set-request sent by an NMS.

set-request Stores a value in a specific variable.

trap An unsolicited message sent by an SNMP agent to an SNMP manager indicating

that some event has occurred.
