The way a switch learns Ethernet (MAC) addresses is by inspecting the Ethernet frame and recording the source MAC address in a dynamic table. The switch will also associate a learned MAC address with a port. It can then make intelligent forwarding decisions based on the destination MAC address. This white paper illustrates the process. 

In this white paper, we'll take a look at access control lists, often referred to as access lists or ACLs (sometimes pronounced "ackels"). 

This white paper highlights two new additions to the Cisco Small Business Network Storage System (NSS) line of products. The Cisco NSS2000 Series is a 2-bay network attached storage (NAS) system, and the Cisco NSS3000 Series is a 4-bay system. 

Build a basic foundation of knowledge about routers, the devices that allow you to move packets between networks, by reading this white paper. 

In this white paper, we examine how to use Wireshark, the world's most popular open-source network analyzer, to troubleshoot some of the top causes of poor network performance, including high latency, packet loss, inefficient window sizes, intercepting devices, and application dependencies. 

This paper summarizes in question and answer format the many critical factors pertaining to VoIP's viability, regardless of which vendor's IP-PBX system is deployed across the distributed enterprise. 

This white paper discusses the role of user profile management. SPs’ efforts to manage, enrich, capitalize on, and provision user information across multiple databases are critical to fuel applications-led service initiatives. 

Network service providers dealing with massive bandwidth demand are struggling to evolve their networks while keeping costs under control. Expenditures must be reduced and revenue per transported bit increased. Read this strategic white paper to learn more about a more value driven approach to network management. 

Modern packet-based communications are sweeping away traditional telephony standards and changing the way businesses stay connected. SIP, the latest IP enabler to hit the market, is often portrayed as the key to implementing more sophisticated, flexible voice and unified communications. But is that a fact, or merely well-publicized fiction? 

Frequently, organizations that operate contact centers are faced with the challenge of working with inadequate telephony equipment. Frustrations range from having to get a few more years out of telephone equipment to having disparate systems. Read this white paper to learn about how contact centers can resolve these telecommunications complexities. 

Check out this white paper for a discussion on network changes; IP address management; Core Network Services solutions; and the benefits of integrated, automated IP. 

In this presentation document, white paper guru Michael Stelzner, author of "Writing White Papers: How to Capture Readers and Keep Them Engaged," will share his secrets on creating effective white papers that attract prospects in droves.
