A fiery debate arises when discussing flow technologies i.e. NetFlow vs. sFlow. As we all know, existing flow technologies act as a vital and viable solution to troubleshoot network and bandwidth issues. While network engineers contemplate which one is better, NetFlow and sFlow serve as an example of how flow technologies…
The performance of applications across the WAN are faced with many issues, such as latency, congestion, and low bandwidth. Your approach to determine how to troubleshoot the issues will vary based primarily on your budget. For those on a limited budget, consider the following lost cost monitoring and troubleshooting…
The evolution in mobile technology has changed the way we work. Gone are the days when work was only done on personal computers. Even laptops have slowly paved way to trendy mobile phones and tablets. With a new and sophisticated device hitting the market on a daily basis with better technological supremacy, employees are…
The Cisco Catalyst 3850 is a fixed, stackable GE (Gigabit Ethernet) access layer switch that converges wired and wireless within a single platform. This switch is based on Cisco’s programmable ASIC named Unified Access Data Plane (UADP) which supports the convergence as well as allows for deployment of SDN and Cisco ONE…
Hi all, We use NTA to count the traffic flowing to and from our customer who has a fixed IP address. When we look at the data in NTA so far this month the customer appears to have used a total of 27Mb (in and out). However, the CDR from our network supplier (CDR for those who aren't aware is a bit like our wholesale bill…
Any ideas why a node would be listed as a NetFlow source in the NTA module when the device is not configured with NetFlow? Selecting the node in the Flow Navigator, there is no NetFlow data associated with the node (of course), but it is listed as a source with two source interfaces, a Multilink and Serial interface. I can…
Quality of Service (QoS) is used in enterprise networks to ensure that business-critical applications have the required priority and are not bogged down by non-business traffic when passing through the enterprise WAN link or even when traversing the Internet. Cisco devices support a QoS model where packets can be treated…
Last week, the Washington DC Circuit Court of Appeals ruled (pdf) that the Federal Communications Commission (FCC) no longer has the authority to require that cable and internet service providers (ISP) treat all internet traffic equally. You have probably heard of this issue already; it's typically referred to as the issue…
NetFlow has become an industry standard for traffic monitoring and is supported on various platforms. Enabling NetFlow on devices helps characterize flows and understand traffic behavior. You can export flow information to perform traffic analysis, bandwidth capacity planning and security analysis. Benefits of using…
Hello Forum, When viewing traffic charts for a specific interface, my quick views show the Top 5 of X but not the remaining traffic which is also important to me. Can someone please guide me on how I can get this 'remaining traffic'? Thanks. EWalls [Orion Platform 2014.1.0, SAM 6.1.0, NPM 10.7, NTA 3.11.0, IVIM 1.9.0]
