SNMP version- 2c (Community- Based SNMPv. SNMP version- 3. The Net: :SNMP module assumes that the user has a basic understanding of the Simple Network Management Protocol and related network management concepts. The Net: :SNMP module abstracts the intricate details of the Simple Network Management Protocol by providing a high level programming interface to the protocol. Each Net: :SNMP object provides a one- to- one mapping between a Perl object and a remote SNMP agent or manager. Once an object is created.
SNMP. A Net: :SNMP object can be created such that it has either "blocking" or "non- blocking" properties. SNMP messages do not return until the protocol exchange has completed successfully or a timeout period has expired. This behavior gives the object a "blocking" property because the flow of the code is stopped until the method returns.
The optional named argument - nonblocking can be passed to the object constructor with a true value to give the object "non- blocking" behavior. A method invoked by a non- blocking object queues the SNMP message and returns immediately. The queued SNMP messages are not sent until an event loop is entered by calling the snmp_dispatcher() method. When the SNMP messages are sent. The event loop exits when all messages have been removed from the queue by either receiving a response. Transport Layer. The default behavior of the methods associated with a Net: :SNMP object is to block the code flow until the method completes.
For methods that initiate a SNMP protocol exchange requiring a response. The undefined value is returned by all methods when a failure has occurred. The error() method can be used to determine the cause of the failure. The hash reference returned by a SNMP protocol exchange points to a hash constructed from the Var. Bind. List contained in the SNMP response message.
The hash is created using the Object. Name and the Object. Syntax pairs in the Var. Bind. List. The keys of the hash consist of the OBJECT IDENTIFIERs in dotted notation corresponding to each Object. Name in the Var. Bind. List. The value of each hash entry is set equal to the value of the corresponding Object.
Syntax. This hash reference can also be retrieved using the var_bind_list() method. When a Net: :SNMP object is created having non- blocking behavior. When a method is invoked that would initiate a SNMP protocol exchange requiring a response. The error() method can be used to determine the cause of the failure.
The contents of the Var. Bind. List contained in the SNMP response message can be retrieved by calling the var_bind_list() method using the object reference passed as the first argument to the callback. The value returned by the var_bind_list() method is a hash reference created using the Object.
Name and the Object. Syntax pairs in the Var. Bind. List. The keys of the hash consist of the OBJECT IDENTIFIERs in dotted notation corresponding to each Object. Name in the Var. Bind. List. The value of each hash entry is set equal to the value of the corresponding Object. Syntax. The undefined value is returned if there has been a failure and the error() method may be used to determine the reason.
When named arguments are expected by the methods. All examples in this documentation use the dashed- option style: $object- > method(- argument => $value); However, the IO: : style is also allowed: $object- > method(Argument => $value); When a Net: :SNMP object has been created with a "non- blocking" property, most methods that generate a SNMP message take additional arguments to support this property.
Most methods associated with a non- blocking object have an optional named argument called - callback. The - callback argument expects a reference to a subroutine or to an array whose first element must be a reference to a subroutine. The subroutine defined by the - callback option is executed when a response to a SNMP message is received, an error condition has occurred, or the number of retries for the message has been exceeded. When the - callback argument only contains a subroutine reference, the subroutine is evaluated passing a reference to the original Net: :SNMP object as the only parameter. If the - callback argument was defined as an array reference, all elements in the array are passed to subroutine after the reference to the Net: :SNMP object. The first element, which is required to be a reference to a subroutine, is removed before the remaining arguments are passed to that subroutine. Once one method is invoked with the - callback argument, this argument stays with the object and is used by any further calls to methods using the - callback option if the argument is absent.
The undefined value may be passed to the - callback argument to delete the callback. NOTE: The subroutine being passed with the - callback named argument should not cause blocking itself.
This will cause all the actions in the event loop to be stopped, defeating the non- blocking property of the Net: :SNMP module. An optional argument - delay can also be passed to non- blocking objects. The - delay argument instructs the object to wait the number of seconds passed to the argument before executing the SNMP protocol exchange. The delay period starts when the event loop is entered.
The - delay parameter is applied to all methods associated with the object once it is specified. The delay value must be set back to 0 seconds to disable the delay parameter. A SNMP context is a collection of management information accessible by a SNMP entity. An item of management information may exist in more than one context and a SNMP entity potentially has access to many contexts. The combination of a context. Engine. ID and a context.
Name unambiguously identifies a context within an administrative domain. In a SNMPv. 3 message, the context. Engine. ID and context. Name are included as part of the scoped. PDU. All methods that generate a SNMP message optionally take a - contextengineid and - contextname argument to configure these fields.
The - contextengineid argument expects a hexadecimal string representing the desired context. Engine. ID. The string must be 1. Once the - contextengineid is specified it stays with the object until it is changed again or reset to default by passing in the undefined value.
By default, the context. Engine. ID is set to match the authoritative. Engine. ID of the authoritative SNMP engine. The context. Name is passed as a string which must be 0 to 3.
The context. Name stays with the object until it is changed. The context. Name defaults to an empty string which represents the "default" context. Net: :SNMP- > session(. This is the constructor for Net: :SNMP objects. In scalar context, a reference to a new Net: :SNMP object is returned if the creation of the object is successful. In list context, a reference to a new Net: :SNMP object and an empty error message string is returned.
If a failure occurs, the object reference is returned as the undefined value. The error string may be used to determine the cause of the error.
Most of the named arguments passed to the constructor define basic attributes for the object and are not modifiable after the object has been created. The - timeout, - retries, - maxmsgsize, - translate, and - debug arguments are modifiable using an accessor method. See their corresponding method definitions for a complete description of their usage, default values, and valid ranges. The Net: :SNMP module uses UDP/IPv. Transport Domain to exchange SNMP messages between the local and remote devices. The module also supports UDP/IPv.
TCP/IPv. 4, and TCP/IPv. Transport Domains. The - domain argument can be used to change the Transport Domain by setting the value to one of the following strings: 'udp. The - domain argument also accepts the strings 'udp', 'udp. Transport Domain of UDP/IPv. The transport address of the destination SNMP device can be specified using the - hostname argument. This argument is optional and defaults to "localhost".
The destination port number can be specified as part of the transport address or by using the - port argument. Either a numeric port number or a textual service name can be specified. A numeric port number in parentheses can optionally follow the service name. This port number will be used if the service name cannot be resolved. If the destination port number is not specified, the well- known SNMP port number 1. By default the source transport address and port number are assigned dynamically by the local device on which the Net: :SNMP module is being used.
This dynamic assignment can be overridden by using the - localaddr and - localport arguments. These arguments accept the same values as the - hostname and - port arguments respectively.
The resolved address must correspond to a valid address of an interface on the local device. When using an IPv. Transport Domain, the transport address can be specified as either an IP network hostname or an IPv. The port information can be optionally appended to the hostname or address delimited by a colon. The accepted IPv. When using an IPv. Transport Domain, the transport address can be specified as an IP hostname (which will be looked up as a DNS quad- A record) or an IPv.
The port information can optionally be included following a colon after the hostname or address. When including this information after an IPv. The scope zone index (described in RFC 4. The accepted transport address formats for IPv. The - version argument controls which other arguments are expected or required by the session() constructor.
The Net: :SNMP module supports SNMPv. SNMPv. 2c, and SNMPv.
The module defaults to SNMPv. The - version argument expects either a digit (i.
