Hubs are better suited for this analysis than switches because they always send all received packets out on all ports. Ideally, the PC and the SNMP master will be directly connected to the same hub. First, select a computer on your network that is as close to your SNMP master as possible.Listed below are the steps for assigning a computer's network interface card (NIC) as the capture interface in Wireshark using a MIB Browser to display SNMP data. A MIB Browser is an invaluable utility for monitoing SNMP devices and application and having a good MIB Browser is indispensible. Paid versions are also available to those who need no restrictions on the numbers of MIBS that are to be loaded while providing additional features. A free version of MIB Browser is available at with some limitation but should have the capabilities that most private users would need. MIB Browser is an SNMP network management utility. Plug-in support is a valuable feature that gives users the ability to dissect new protocols that Wireshark may not be able to by default. Filters can be used to show only certain pieces of data while color-coding can make it easier for the user to read the data that is displayed onscreen. It has features such as filters, color-coding, and plug-in support. You can use Wireshark to capture, filter, and inspect network data packets. Wireshark is a network protocol analyzer and is available at no cost from It is a free open-source utility that has found itself of use to many different people and is the recipient of many awards. Free tools such as the open-source Wireshark packet analyzer and the MIB Browser from iReasoning make network troubleshooting accessible while also being cost-free. A combination of a packet analyzer and a MIB Browser can you help you troubleshoot a variety of network performance problems. It doesn't matter who the manufacturers of your Simple Network Management Protocol (SNMP) remote are. Wireshark is a forked version of Ethereal and so migrating from Ethereal to Wireshark should be relatively simple and straight forward. It is advisable that users of the Ethereal version integrate into using Wireshark. As of currently, software development on the Ethereal packet analyzer has been halted while development on the Wireshark version will continue.

Any mentions of the Ethereal packet analyzer should now be referred to the Wireshark packet analyzer instead. *The packet sniffer/analyzer known as Ethereal is now called Wireshark. Previous Page: In-Depth Techniques to Identify and Solve Stubborn SNMP Problems
