Synchronization of SSH Key in CCM
When communicating with the device, Cisco Prime Network CCM operations use the SSH keys that are 
stored in the known_hosts file. This file is available in the /.ssh/known_hosts 
directory. If there is a mismatch in the SSH key and if the automatic key synchronization feature is 
enabled, then the Cisco Prime Network CCM script...

Verifying SSH key Resync on VNE
To verify SSH key resync on VNE, follow the steps provided below:
Step 1Model the VNE using SSHv2. Refer Enabling Server Authentication Settings, page 3-21.
Step 2Enable resync on the device. Refer Enabling SSH key synchronization, page 3-21.
Step 3Log into the device, and change the key in the device.
NoteFor VNE, a DSA key change...

  Enabling SSH Resync on VNE and CCM
On performing a DSA key change, the DSA key entries are not updated in the known_host files. 
However, this does not impact any CCM operation. In other words, irrespective of the resync value (true 
or false), the CCM operations are always successful.

Setting Up Vision Client Maps
Vision client maps display devices and their physical and logical relationships, including relationships 
with logical NEs such as services. From a map, users can drill down into both the physical and logical 
NE details and perform other operations, such as launching command scripts and external applications. 
These topics explain how to set up maps:

Workflow for Creating a Map
Use maps to highlight different segments of your environment. For example, you could create one map 
to display the BGP architecture and relationships between NEs, and another map to display the physical 
connectivity of the network. You can create maps that cover specific network segments, customer 
networks, services, or any other mix of network elements...

Naming Your Maps
The name you assign a map is a significant way to organize the NEs in your network. Use these 
guide4.3.2 when naming maps:
Give each map a specific function. For example, do not mix network and service elements together 
in a map.
Give each map a name that reflects the map function, such as:
–Core Devices for a...

  Creating a New Map and Add NEs to the Map
Step 1Choose File > New Map, and enter a map name that reflects the service.
Step 2Click the tab for your new map and choose File >Add to Map. The following figure shows the service 
types you can choose.
If you choose VPN > New, the Create VPN dialog box is displayed. For information on creating a VPN, 
see Creating a VPN, page 17-22.

Creating a Special-Purpose Map
You can create a special-purpose map by selecting specific link types for your map, such as a map that 
shows all the BGP links in the network.
TipDo not mix logical and physical links into one map because they can be displayed the same way. Link 
types can only be ascertained by hovering the mouse over the...

These are some examples of what you can create using the various link types:
Process map with all BFD links
Traffic map with all Frame Relay links
Tunnel map with all GRE tunnels
The link type also determines the algorithm Prime Network will use for the may layouts (symmetrical, 
orthogonal, and so forth).
