====== Network Explorer ======

{{tools:network-explorer.png|}} The network explorer tool presents the network in a tree structured manner.

===== Navigation =====
 
The initial view lists all the routers ([[categoriesandtypes|GW and GSW]]). The user may explore a router by clicking on the plus sign (+). This will open a router interface listing for this router.
If the tag "show detailed information" is checked details on IP addresses and router interface descriptions is also shown.

If further topology for a given router interface is known; i.e. which switch the router interface connects to, you can drill down further by clicking on a second level plus sign (+). You can keep on exploring the subnet in question in this manner. For each switch the switch ports that are configured for this subnet/vlan will be displayed. 

   * A double arrow indicates a vlan tagged (trunked in Cisco terminology) connection.
   * When the switch port connects to end equipment the port name is shown. A drill down on end equipment will show you the IP and mac address(es) behind the given port.


===== Search options =====
 
You may find it useful to use the network exlorer search option. You may look for:

  * a particular sysName or a substring match (check "show exact/no substring match" if you want exact matches only
  * a particular IP address
  * a mac address: does a machine track search (delimiter ':' is allowed or none, do not use '-'). 
  * a port name (port description)
  * a vlan, i.e. all switch ports that belong to the vlan in question
  * a room, i.e. all equipment that is in a given room 
  * Software (not sure how this works...)
  * Serial (not sure how this works...)
