SharpSnmpLib Helper utility that performs data conversions from/to bytes. Converts decimal string to bytes. The decimal string. The converted bytes. " 16 18 " is converted to new byte[] { 0x10, 0x12 }. Converts the byte string to bytes. The HEX string. The converted bytes. "80 00" is converted to new byte[] { 0x80, 0x00 }.

(0-5 are first defined in SNMP v1, and others are added in v2) There was no problem performing the request. The response to your request was too big to fit into one response. An agent was asked to get or set an OID that it can't find; i.e., the OID doesn't exist. A read-write or write-only object was set to an inconsistent value. This error is generally not used. The noSuchName error is equivalent to this one. This is a catch-all error. If an error occurs for which none of the previous messages is appropriate, a genError is issued. A set to an inaccessible variable was attempted. This typically occurs when the variable has an ACCESS type of not-accessible. An object was set to a type that is different from its definition. This error will occur if you try to set an object that is of type INTEGER to a string, for example. An object's value was set to something other than what it calls for. For instance, a string can be defined to have a maximum character size. This error occurs if you try to set a string object to a value that exceeds its maximum length. A set operation was attempted using the wrong encoding for the object being set. A variable was set to a value it doesn't understand. This can occur when a read-write is defined as an enumeration, and you try to set it to a value that is not one of the enumerated types. You tried to set a nonexistent variable or create a variable that doesn't exist in the MIB. A MIB variable is in an inconsistent state, and is not accepting any set requests. No system resources are available to perform a set. This is a catch-all error for set failures. A set failed and the agent was unable to roll back all the previous sets up until the point of failure. An SNMP command could not be authenticated; in other words, someone has supplied an incorrect community string. A variable will not accept a set, even though it is supposed to. You attempted to set a variable, but that attempt failed because the variable was in some kind of inconsistent state. Gauge32 type. Creates a instance from raw bytes. Creates a with a specific .

Left object Right object Returns true if the values of its operands are not equal, false otherwise. The comparison. Left object Right object Returns true if the values of its operands are not equal, false otherwise. Generic trap code. Indicates that the agent has rebooted. All management variables will be reset; specifically, Counters and Gauges will be reset to zero (0). One nice thing about the coldStart trap is that it can be used to determine when new hardware is added to the network. When a device is powered on, it sends this trap to its trap destination. If the trap destination is set correctly (i.e., to the IP address of your NMS) the NMS can receive the trap and determine whether it needs to manage the device. Indicates that the agent has reinitialized itself. None of the management variables will be reset. Sent when an interface on a device goes down. The first variable binding identifies which interface went down. Sent when an interface on a device comes back up. The first variable binding identifies which interface came back up. Indicates that someone has tried to query your agent with an incorrect community string; useful in determining if someone is trying to gain unauthorized access to one of your devices. Indicates that an Exterior Gateway Protocol (EGP) neighbor has gone down. Indicates that the trap is enterprise-specific. SNMP vendors and users define their own traps under the private-enterprise branch of the SMI object tree. To process this trap properly, the NMS has to decode the specific trap number that is part of the SNMP message. GETBULK request PDU. Creates a with all contents. The request id. Non-repeaters.
