Zoom Map Out

The Zoom Out function shrinks the entire map, both the size of the nodes as well as the spacing
between them. To Zoom Out the current map, do one of the following:
Select Zoom Map Out from the Map menu.
●
Click the Out icon on the icon bar.
●
Enter [Ctrl] and the [Minus] from the numeric keypad on the keyboard.
●
Unlike the other map manipulation commands, the zoom level is not saved with the map.

Unzoom Map

The Unzoom Map function restores the map to the size it was prior to any Zoom In or Zoom Out
actions. To "unzoom" the map, do one of the following:
Select Unzoom Map from the Map menu.
●
Enter [Ctrl]+R from the keyboard.

Sync Links for Map or Sync Links for All Maps

EPICenter uses a combination of SNMP traps (EDP and LLDP) and periodic polling to collect topology
connectivity information. Occasionally a device trap may be lost, or a device poll operation may be
unsuccessful, making the EPICenter topology view temporarily out of sync with the actual network
state.
EPICenter will eventually synchronize with the network state at the next successful polling cycle. It will
discover new links between devices, or rediscover links that have been previously removed from the
map if they are real links that are up. However, if you want to have EPICenter discover new links
immediately, instead of waiting for the next polling cycle, you can use one of the Sync Links
commands (Sync Links for Map or Sync Links for All Maps).
You can also use Sync Links for Map to remove links that no longer exist. Since EPICenter cannot
distinguish between a link that no longer exists and a link that is down, when a link is moved,
EPICenter will continue to show the obsolete link as a down link. Doing a sync on the device (from the
Inventory Manager) does not affect this, you must use the Sync Links commands to remove obsolete
links from the map.
To have EPICenter rediscover all existing links between devices on the current map, do the following:
Select Sync Links for Map from the Edit menu.
●
To have EPICenter rediscover all existing links between devices on all map, do the following:
Select Sync Links for All Maps from the Edit menu.
●
EPICenter will add or update the links that exist between the devices on your map(s), and will remove
any links whose connectivity or status it cannot determine. If status is updated for a given device, and
that device appears on multiple maps, this will affect the link status of that device on all maps on which
it is present.
A small pop-up will appear asking you to wait while the synchronization operation is in progress.
