Free snmp network software for windows

A Freeware Cisco Configuration Management Application Cisco Snmp Tool is a free tool that was developed as a Cisco Configuration Management Application.
After 2.0 Beta there is a map interface which supports visual design of your network. Program can be used at LAN and WAN networks.
But never forget to increase timeout and retry values at WAN networks. Typically 2000ms timeout and 2 retry values are enough for both LAN and WAN applications.
Main features:
- Cisco Configuration Download. (startup or running)
- Cisco Configuration Upload. (startup or running)
- Device reset and Write NVRAM execution.
- Telnet and Ping Device Function.
- Nat Support. (If you are behind a firewall type NAT address)
- Easy Network Map interface.
- Realtime Device Up/Down Monitoring. (for now just ping method is used)

AdventNet SNMP API .NET Edition is a comprehensive development toolkit for SNMP-based network management applications. AdventNets SNMP stack comprises a set of powerful .NET SNMP library to build real-time applications for monitoring and tracking network elements that are reliable and scalable.
The .NET SNMP library provides off-the-rack components for trap and table handling and the basic SNMP operations: SNMP GET, SNMP GETNEXT, SNMP GETBULK, and SNMP SET. These components enable simpler and faster development and deployment of SNMPv1 and SNMPv2c management applications that can be integrated into any network management solution.
AdventNet SNMP Utilities provides off-the-shelf components for trap and table handling along with basic SNMP operations, such as SNMP GET, SNMP GETNEXT, SNMP GETBULK, and SNMP SET.
AdventNet SNMP API can be used to build either a two-tier or a three-tier management application. In the two-tier architecture, the management application directly communicates with the agents. In the three-tier architecture, the management application communicates with the agents through a manager-server. For building highly scalable management applications, three-tier architecture is the best option
AdventNet SNMP API consists of a hierarchy of .NET packages that enables rapid development of element and network management applications for a wide variety of domains.It is built upon a layered architecture, which contains the SNMP Package and the Transport Provider Framework, and the MIBs API.
AdventNet provides affordable software for management and provisioning of complex networks, systems, and IT applications and for database migration. With a broad product portfolio and an active customer base ranging from enterprises, equipment vendors, and service providers, AdventNet has emerged as a very affordable and high-quality alternative to expensive software that is common in this industry.

Free SNMP provides basic support for Simple Network Management Protocol (SNMP), allowing users to perform such tasks as viewing and browsing MIBs, performing Walk operation. The tool is designed with a user-friendly interface and is easy to use.

SNMP Trap Watcher is built to be used to receive SNMP Traps from network equipment, including routers, switches, and workstations.
Traps are sent when errors or specific events occur on the network. Traps are normally only sent to end stations which are currently sending SNMP requests to the device in question, using applications such as SNMP Manager or HP OpenView. However, some devices can be configured to send Traps to specific management station addresses.
SNMP Traps are sent on UDP port 162, and SNMP Trap Watcher allows Traps to be filtered by string or by type (Enterprise specific or Generic). Using the Decode Window, and selecting a specific Trap from the list, a full decode of the Trap can be displayed. This option is more useful for debugging Network equipment which is in the early stages of development.
