-The netmap is available from the toolbox. Clicking it will redirect you to the javascript netmap application. +The netmap is available from the toolbox.
- +
-The page starts with loading the javascript application (big loading spinner, keeps spinning until it has loaded its required resources. This will go for the next times you visit netmap, as the resources will then be cached in your browser.). +
-The spinner will decrease in size when the javascript application is loaded and it starts "​running the application"​ and continue to load the network topology information.  +
- +
-The first thing you'll see is that the navigation menu on the left side is loaded, and soon after the network topology graph pops up. Depending on your loading a view with fixed nodes or not, the layout algorithm will do it's work and position nodes as good as making the nodes not collide.  +
- +
-Your presented with two navigation bars, one on each side of your screen that you can toggle by clicking the "<<"​ or ">>"​ links. You can toggle fullscreen with CTRL+SHIFT+F which toggles both sidebars and NAV's footer and header.  +
-In the center your presented with the network topology map it self.  +
- +
-The load colors on edges represent load based on the link's capacity, and the link's weight represents a few static categories of link speeds. (0-100, 100-512,​512-2048,​2048-4096,>​4096 Mbit/s) +
-Using the traffic gradient popup can help you tell the load % without having to click on a link to read it's traffic data+
  
 +Netmap consists of two navigation bars, one on each side of the screen, and the map itself. The navigation bars can be toggled by clicking the "<<"​ or ">>"​ links. ​ You can toggle fullscreen with CTRL+SHIFT+F.
  
 +The load colors((Click "Show gradient"​ to get an overview of what the colors indicate)) on edges represent traffic load based on the link's capacity, and the link's thickness represents the link speed. ​

-Starting on the left navigation bar, your presented with a:+The left navigation bar has options for filtering and controlling the behaviour of the map.
  
 +=== Searchbox ===
  
 +This searches for the name of a netbox and centers the map on it. If the search hits several netboxes the map will center on the first.
  
-=== Searchbox ​===+=== Zoom to extent ​===
  
-Type in part of the sysname of the box your looking for, it run loop thru it dataset and stop on the first match it hits and fetch it's graph position and translate the node to be centered in the graph. At the moment the search is quite simple, but in the _future_ it will have support for finding the bounding box for all matches and translate the bounding box to it's view port and set correct zoom level. ​Zoom to extent will try it's best to position ​the bounding box for the whole graph in the center of the view port and scale out so you can see it. A tip is to just click it a few times so it gets it right ;-) (or wait for the layout algorithm to finish) ​+Zoom to extent will try to position the whole graph in the center of the view port and scale out so you can see it.

-You can run filters on the loaded network topology graph, pr. default the GSW,​GW,​SW,​OTHER,​WLAN,​SRV,​ and EDGE categories ​are selected on by default. Here you can deactivate active filters, and nodes of the deactivated filters will disappear. You can toggle this filters back and forth without having to reload the network topology graph, it will only '​bounce'​ the layout algorithm ​to make sure the nodes aren't colliding+Choose what categories ​of netboxes ​you want to see.

-As you play around with filters, or NAV '​topology analyzer'​ ([[http://​nav.uninett.no/​backendprocesses#​ipdevpoll|ipdevpoll]] / [[http://​nav.uninett.no/​backendprocesses#​topology|topology]]) there is certain ​to render single instance ​nodes which is nodes who has no relations ​to any other nodes in the current state of active filters.  ​Here you have the option to disable or enable em.  +  * **Filter orphans**Uncheck this to hide nodes with no links to other nodes. 
- +  * **Mark by position**: Mark nodes that are located in the same room or location. This is shown by drawing a red circle around the nodes who are related to the selected node. 
-=== Mark by position ​=== +  * **Pause force algorithm**: Pause the layout algorithm by clicking the button. A green icon indicates active algorithm, a red an inactive ​algorithm. ​Resume ​it by drag and dropping a node, unfix a node, unfix all nodes or clicking the button again. 
- +  * **Fix or unfix all nodes**: Set all nodes to fixed or unfixed. Fixed nodes will not move when running the algoritm.
-Option to mark other related ​nodes that are either ​located in the same room or location. This is shown by drawing a red circle around the nodes who are related to the selected node.  +
