Chapter First Actions 7 0 Overview Remote IP devices are managed on the basis of manager agent paradigm powered by SNMP protocols Prior to issuance of any SNMP commands the following prerequisites are to be identified and observed Version of SNMP protocol supported by the remote network device This is essential since availability of commands varies across versions For instance Get Bulk command is supported under SNMP v2 and v3 protocols only Type of actions supported by the device architecture If a particular property exposed for management is defined to be of a scalar data type then SNMP commands such as Get Table become irrelevant Access type as defined in object characteristics If a specific object has read only access then data retrieval operations only can be performed on that object If data retrieval as well as data modification operations are to be performed the object should have either read write or write only access types defined in the MIB The following table summarizes the type of objects appearing in the object hierarchy as seen in the tree view and the range of possible SNMP commands 1 2 Object Icon GetBulk GeTable Set Type aa N v1 Node Scalar aj v1 v1 v1 Vv M Get command can only be performed from the tree and schema views 7 1 SNMP Operations Depending on the initiator of the commands SNMP operations can generally be classified into the following two categories
3. Messages originating from SNMP manager These messages can take the form of command request and involve either Data retrieval or Data modification operations These commands are essentially based on request response model These operations are classified according to their read write nature as follows Data retrieval operations Data altering operations Get Get Next Get Bulk Get Table Walk Set Messages originating from SNMP agent Under critical situations like performance degradation or network failure the concerned SNMP agent itself will send messages to SNMP agent that may or mat not be responded in turn by the SNMP manager These messages are of the following types e SNMP Traps e SNMP inform notifications 7 2 Get Get command is issued to query and collect the value of a single specified object managed by the SNMP agent Get command is applicable to scalar and columnar objects only For individual scalar objects Get command can be issued from the tree view while the schema view displays the related scalar objects together and makes it possible to issue a single Get command which collects values of all scalar objects at a time Get operations are permitted only for objects whose access or max access values do not values preventing data retrieval such as write only or not accessible Get command is applicable to scalar and columnar objects only Tree View In order to retrieve the value of managed in
