Workflow for device discovery

Stages
Preconfigure device for management
 

Configure the Nokia and GNE devices for management; see Chapter 8, Device commissioning and management .


Configure SNMP
 

As required, enable SNMPv3 device management; see To enable SNMPv3 management of a device .


As required, enable or disable SNMP streaming on a device for configuration data transfers to the NFM-P; see To enable or disable SNMP streaming on an NE .


Configure SSH
 

As required, configure SSH for secure device CLI access.

  1. Configure SSH servers on devices; see the device documentation for configuration information.

  2. Ensure that SSH2 is enabled on devices; see To verify that SSH2 is enabled on a device .

  3. Enable SSH2 host key persistence on devices that support host key persistence; see To enable SSH host key persistence on a device .


Configure device mediation
 

Specify the network mediation parameters, and optionally configure the following mediation policies for devices in specific discovery rules; see To configure device mediation :

  • MIB entry policies that define how to poll specific device MIBs for changes

  • management ping policies that define periodic device connectivity checks

  • event notification policies that define how the NFM-P processes SNMP traps


As required, assign event notification policies to devices; see To assign an event notification policy to an NE .


Configure additional management networks
 

If required, configure one or more additional management networks.

  1. Define the management network and subnets to associate with non-default management interfaces on main and auxiliary servers; see To configure a management network .

  2. Create additional main-server management interfaces; see To configure an additional management interface on a main server .

  3. Create additional auxiliary-server management interfaces; see To configure an additional management interface on an auxiliary server .


Configure device discovery
 

If required, create a workflow for post-discovery actions using Workflows.


If required, create post-discovery actions; see To configure a post-discovery action .

Note: You can also create post-discovery actions during discovery rule creation.


10 

Create the required device discovery rules and use the rules to discover devices; see To configure a discovery rule .


11 

Manage discovery rules; see To enable, disable, or delete a discovery rule .


12 

As required, manage the post-discovery actions in discovery rules.

  1. View the execution status of an associated script; see To view the post-discovery action execution status .

  2. Manually execute a failed script; see To manage a post-discovery action failure on an NE .


Incidental tasks
 
13 

As required, perform the following.

  1. Change the management state of a device; see To manage, suspend, or unmanage a device .

  2. Change from SNMPv2c to SNMPv3 management of a device; see To change from SNMPv2 to SNMPv3 management of a device .

  3. Switch from non-secure to secure mediation; see To switch from non-secure to secure mediation .

  4. Specify which management IP address is saved for a device when the device is set to an unmanaged state; see To specify which management address the NFM-P uses to remanage a device .

  5. Rescan the network using a discovery rule; see To rescan the network for a device according to a discovery rule .

  6. Synchronize the NFM-P information with the device configuration; see To partially or fully resynchronize NEs with the NFM-P database .

  7. Manage SSH2 host key acceptance; see To manually accept a mismatched SSH host key and To view the SSH2 host keys to identify active and mismatched keys .

  8. View and save collected SNMP MIB information; see To list and save SNMP MIB information .

  9. Delete a device from the NFM-P; see To delete a device from the managed network .
