This is an old revision of the document!
Netmap has these features (in no particular order):
NOTE: Icons for the following categories are included GSW, GW, OTHER, SRV, SW, WLAN, EDGE and the fictive category ELINK. If you have other categories, put an icon with the category name in $NAV_ROOT/share/htdocs/images/netmap/ in the png format. Note: use lower case filename of the category name.
The netmap is available from the toolbox.
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 colors1) on edges represent load based on the link's capacity, and the link's thickness represents the link speed.
Nodes and be drag and dropped and positioned to your liking. When a view is saved, it will save current zoom/scale, position of the map, active network topology layer, categories (orphan filter) as meta data to it's view. Nodes get fixed and auto selected automagically after a drag and drop. In the netbox view you have an option to easily uncheck it again if you want to.
Starting on the left navigation bar, your presented with a:
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)
Radio button to toggle which network topology view you want to view, either layer 2 or layer 3. Shouldn't require any further explanation, if you need .. look into the OSI model.
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.
As you play around with filters, or NAV 'topology analyzer' (ipdevpoll / 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.
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.
You can resume it by drag and dropping a node, unfix a node, unfix all nodes etc.
Enable or disable auto clicking of a node when simply hovering a link or node. This can also be toggled with the keyboard shortcuts «n» or «l» (lowercase of L).
A button to open the traffic load scale used in netmap in a popup.
A drop down / combi box which shows your available views. Your own views are listed at the top and public views are listed below it. The selected view is always rendered as the first choice in the drop down.
If the view has a description, it will be shown below the “Save” and “Favorite” buttons.
The save button is a button for updating changes to a selected view, if the view isn't saved it will trigger a “Save new as”. You probably also noticed the “+” and “-” buttons on the right side, the “+” button is always known as “Save new as” and the “-” button is known for “Delete active view”. Careful, there is no confirmation dialog when deleting a view and as an administrator you are allowed to delete any view!
A heart will popup if the selected view is the user's favorite view.
= Save new view =
Popups up a modal form, where you can enter title for the view (shown in dropdown) and a longer description if that is needed. A checkbox is available to select if the view should be open for other users in netmap or private.
This is the view that will render with a Netbox or Link template for a selected netbox or link. If your an administrator, a link to the administration area will be available at the bottom here. Depending on which network topology layer you have active, it will render a bit different information.
Renders the sysname and it's management IP first together with the “pping” indicator of the netbox is up or down. (this is atm only loaded at network topology graph load, in the future this will automagically refresh)
A checkbox for knowing if the node's position is fixed or unfixed in the graph. Fixed positions is what get's saved when your saving a view.
Category is the netbox's category.
(Missing atm: Device type ;-( )
Room and location information.
If layer2, render VLAN information and option to select a vlan. When clicking on a VLAN, it will mark other nodes and links that is member of the current VLAN in it's broadcast domain.
If layer3, render netident and netdescription together with active prefixes over this link.
Renders from netbox [interface] to netbox [interface]
Link speed of the link.
Traffic in and out. (from: in , out: to) Example: netbox A and B, a is listed first. That means you will read it like this: netbox A A is receiving 200mbps in and transfers 400mbps out to B.
