Supports the Flexible NetFlow - Top N Talkers Support feature. No configuration tasks are associated with the Flexible NetFlow - Top N Talkers Support feature. Therefore, in order for you to use the Flexible NetFlow - Top N Talkers Support feature, traffic analysis with Flexible NetFlow must already be configured on the networking device. Information About Flexible NetFlow - Top N Talkers Support Flexible NetFlow Data Flow Filtering The flow filtering function of the Flexible NetFlow - Top N Talkers Support feature filters the flow data in a flow monitor cache based on the criteria that you specify, and displays the data. The flow filtering function of the Flexible NetFlow - Top N Talkers Support feature is provided by the show flow monitor cache filter command. For more information on the show flow monitor cache filter command, refer to the Cisco IOS Flexible NetFlow Command Reference. Flexible NetFlow Data Flow Aggregation Flow aggregation using the show flow monitor cache aggregate command allows you to dynamically view the flow information in a cache using a different flow record than the cache was originally created from. Only the fields in the cache will be available for the aggregated flows. The flow aggregation function of the Flexible NetFlow - Top N Talkers Support feature is provided by the show flow monitor cache aggregate command. For more information on the show flow monitor cache aggregate command, refer to the Cisco IOS Flexible NetFlow Command Reference. Flow Sorting and Top N Talkers The flow sorting function of the Flexible NetFlow - Top N Talkers Support feature sorts flow data from the Flexible NetFlow cache based on the criteria that you specify and displays the data. You can also use the flow sorting function of the Flexible NetFlow - Top N Talkers Support feature to limit the display output to a specific number of entries (top n talkers, where n is the number or talkers to display) by using the top keyword of the show flow monitor cache sort command. The flow sorting and Top N Talkers function of the Flexible NetFlow - Top N Talkers

Support feature is provided by the show flow monitor cache sort command. For more information on the show flow monitor cache sort command, refer to the Cisco IOS Flexible NetFlow Command Reference. Combined Use of Flow Filtering and Flow Aggregation and Flow Sorting with Top N Talkers Although each of the show commands that make up the Flexible NetFlow - Top N Talkers Support feature can be used individually for traffic analysis, they provide much greater analytical capabilities when they are used together. When you use any combination of the three show commands, you enter only the common prefix of show flow monitor monitor-name cache followed by filter , aggregation , or sort , and the arguments and keywords available for filter , aggregation , and sort , as required. For example, show flow monitor monitor-name cache filter options aggregation options sort options where options is any permissible combination of arguments and keywords. See the "Configuration Examples for Flexible NetFlow - Top N Talkers Support " section for more information. Memory and Performance Impact of Top N Talkers The Flexible NetFlow - Top N Talkers Support feature can use a large number of CPU cycles and possibly also system memory for a short time. However, because the Flexible NetFlow - Top N Talkers Support feature uses only show commands, the CPU usage should be run at a low priority because no real-time data processing is involved. The memory usage can be mitigated by using a larger granularity of aggregation or no aggregation at all. How to Analyze Network Traffic Using Flexible NetFlow Top N Talkers Filtering Flow Data from the Flexible NetFlow Cache This task shows you how to use the show flow monitor cache filter command with a regular expression to filter the flow monitor cache data and display the results. For more information on regular expressions and the show flow monitor cache filter command, refer to the Cisco IOS Flexible NetFlow Command Reference. Perform this task to filter the flow monitor cache data using a regular expression and display the results. SUMMARY STEPS enable show flow monitor [name

Flexible NetFlow - Top N Talkers Support This document contains information about and instructions for using the Flexible NetFlow - Top N Talkers Support feature. The Flexible NetFlow - Top N Talkers Support feature helps you analyze the large amount of data that Flexible NetFlow captures from the traffic in your network by providing the ability to filter, aggregate, and sort the data in the Flexible NetFlow cache as you display it. When you are sorting and displaying the data in the cache, you can limit the display output to a specific number of entries with the highest values (Top N Talkers) for traffic volume, packet counters, and so on. The Flexible NetFlow - Top N Talkers Support feature facilitates real-time traffic analysis by requiring only the use of show commands, which can be entered in many different variations using the available keywords and arguments to meet your traffic data analysis requirements. NetFlow is a Cisco technology that provides statistics on packets flowing through the router. NetFlow is the standard for acquiring IP operational data from IP networks. NetFlow provides data to support network and security monitoring, network planning, traffic analysis, and IP accounting. Flexible NetFlow improves on original NetFlow by adding the capability to customize the traffic analysis parameters for your specific requirements. Flexible NetFlow facilitates the creation of more complex configurations for traffic analysis and data export through the use of reusable configuration components.

While many brands on the market manufacture personal amplifiers, the one specifically known for creating Pocket Talkers is called Williams Sound, it isn’t the most popular brand. Still, if you want to get the best Pocket Talker, this is where you need to go. It’s an American brand that has been working on several forms of communication systems for decades. As a result, Williams Sound Pocket Talkers are some of the best-rated personal amplification devices on the market. What Makes a Pocket Hearing Aid a Good Option? As discussed in the next section, only one brand offers Pockettalkers, Williams Sound. However, the Pocket Talker hearing device falls under the general category of personal amplifiers.These are budget-friendly alternatives to hearing aids (or you may use them in conjunction). This excellent product works great for hearing the conversation better in small groups, watching TV, and much more. It’s a good hearing aid for senior citizens at events and crowded areas.The main purpose of sound amplifiers is for you to hear speech more clearly, whether in a classroom, in personal conversations, on television, or in any other similar situation. Sound amplifiers tend to get rid of background noise. The more they can eliminate background noise, the better you
