![]() ![]() Define a flow record by specifying key and nonkey fields of interest. Configuring NetFlow on a Nexus switch consists of following steps: ![]() These questions help users make the right choice of applying a Layer 3 or Layer 2 NetFlow configuration. Is the box switching packets within VLANs or routing them across VLANs using Switched Virtual Interfaces (SVI)? What kind of interfaces are present on the box? 元 or L2 interfaces? What type of information are users looking for? MAC fields or IPv4/v6 fields? For such challenges, answering the following questions can assist: Network operators and architects often wonder where to attach the NetFlow monitor. The FNF design gives the following levels benefits:įlexibility to choose the definition of a flow (the key and nonkey fields)įlexibility to selectively apply different flow definitions to different interfacesįlexibility to choose the exporter interfaceĮxtensibility to future improvements, such as IPFIX The NetFlow version is template based, so users can specify what data has to be exported. Flexible NetFlow provides support for IPv6 as well as L2 NetFlow records. Flexible NetFlow (FNF) is standardized on Version 9 NetFlow and gives users more flexibility on defining flows and the exported fields for each flow type. The user can select a few other fields, but NetFlow Version 5 has limitations on the details it can provide. By default, a flow is defined by seven unique keys: With traditional NetFlow, all the keys and fields exported are fixed and it supports only IPv4 flows. NetFlow assists with validating traffic engineering or policy enforcement at any point in the topology.Ĭisco NX-OS supports both traditional NetFlow (Version 5) and Flexible NetFlow (Version 9) export formats, but using flexible NetFlow is recommended on Nexus platforms. In addition to traffic rate, NetFlow provides QoS markings, TCP flags, and so on for specific applications, services, and traffic flows at each point in the network. NetFlow does not require engineering the network around the instrumentation it follows the traffic through the network over its natural path. Network traffic is often asymmetrical, even on small networks, whereas probes typically require engineered symmetry. NetFlow provides operators with network and security monitoring, network planning, traffic analysis, and IP accounting capabilities. NetFlow is a Cisco feature that provides the capability to collect statistics and information on IP traffic as it enters or exits an interface. ![]()

![]() ![]() In MuseScore, select a rest, press N, then select a duration.Layout your screen to see both VMPK and MuseScore.Start VMPK and select Edit -> MIDI connection -> Midi out port, choose LoopBe Internal MIDI (all windows 32 or 64 bits) or In from MIDI Yoke 1 (does not work on Windows 7).Choose Port MIDI interface and select LoopBe Internal MIDI or Out to MIDI Yoke 1 Start MuseScore, and select Edit -> Preferences -> I/O.Please note that both MIDI cable are free as in beer but not as in speech.If you are not familiar with virtual midi cable, VMPK's website has a nice tutorial. You can setup MuseScore to work together with Virtual MIDI Piano Keyboard to be able to input notes from the piano into MuseScore. I will try to do the same for Mac and Linux as well. Use this option if you want the OSK to suggest words for you as you type so you don't need to type each complete word.Here is a proposition for a new page in the handbook or as a tutorial somewhere? Please let me know if you think it is valuable. Scan mode highlights areas where you can type keyboard characters by pressing a keyboard shortcut, using a switch input device, or using a device that simulates a mouse click. Use this mode if you want the OSK to continually scan the keyboard. The characters you point to are entered automatically when you point to them for a specified time. Use this mode if you use a mouse or joystick to point to a key. Use this mode if you prefer to click or tap the on-screen keys to enter text. Use this option to expand the OSK to show a numeric keypad.Ĭlick on keys. Use this option if you want the keys to light up as you type. Show keys to make it easier to move around the screen. Use this option if you want to hear a sound when you press a key.

You can also select if you want to insert a space after each predicted word. Use Text Prediction: Use this option if you want the OSK to suggest words for you as you type so you don't need to type each complete word. You can also choose any combination of the following options for selecting a key:Ī joystick, game pad, or other gaming deviceĪ keyboard key that you can choose from a list Scan mode highlights areas where you can type keyboard characters by pressing a keyboard shortcut, using a switch input device, or using a device that simulates a mouse click. Use the Scanning speed slider to set a speed that suits your preferences. Scan through keys: Use this mode if you want the OSK to continually scan the keyboard. Use the Hover duration slider to adjust the delay. The characters you point at are entered automatically when you point at them for a specified time.
