Importing network device data

The CiscoWorks import tool creates network device entries in the datastore. The import tool creates and updates Network Device nodes.

Entries in the datastore for a network device are overwritten if a network device in the input data has the same name.

A limitation of the importer is that a network device already in the datastore for which a matching name cannot be found in the input data will not be removed. Therefore if a network device has been renamed since a previous import, it will appear in the datastore as a second network device.

Importing data from CiscoWorks

The CiscoWorks importer loads the data file exported from CiscoWorks LMS using the Campus Manager User Tracking tool, and loads any existing network device data from the BMC Atrium Discovery datastore. It then compares the sets of data. The supported versions are Campus Manager 3.x and 4.x (UT CLI 1.0, 1.1, and 1.1.1).
The network device name is used as the index. Therefore, if two network devices have the same name, they are treated as the same network device.

• If a new network device is found in the exported file, it is added to the BMC Atrium Discovery datastore. The name of the network device is used as its primary key. See the note below regarding deletion of network devices.
• The ports on each network device are updated. These are indexed by IP address (the primary key). Port attributes that are updated include speed, duplex, and IP address. New ports (identified by IP address) are added, and any ports removed from the CiscoWorks data are removed from the datastore.

Importing a CiscoWorks data file

To import a CiscoWorks Data File:

1. From the Discovery section of the Administration tab, select Ciscoworks Import.
   The options on this page are described below:

   Field Name	Details
   File To Upload	The file to upload. Click Browse... to display a file browser window. Select the file to import and click Open.
   File Type	Choose the type of file to import. Choose either XML or delimited from the File Type list. If you select XML, the lists for File Delimiter and File Has Header Line are dimmed.
   File Delimiter	For a delimited file only, select the delimiter type from the File Delimiter list. This can be one of Comma, Tab, or Space.
   File Has Header Line	Choose Yes or No from the File Has Header Line list depending on whether the delimited file has a heading line.
   Remove existing Network Devices	Do you want to remove existing network devices from the BMC Atrium Discovery datastore that are not present in the file you are importing? Choose Yes or No from the Remove existing Network Devices list.
   Logging Level	Choose the logging level from the Logging Level list. This can be Debug, Info, Warning, Error, or Critical.

2. To import the CiscoWorks data file, click Apply.

There is also a command line utility available for importing CiscoWorks data. It is described in tw_imp_ciscoworks.

Generating CiscoWorks data

To export data from CiscoWorks in a layout which the importer can use, you must create a custom layout. To do this:

1. From the CiscoWorks LMS Portal, select Reports.
2. Select Custom Layouts.
3. Click Create.
4. In the Add Layout dialog box, select End Host.
5. Select the columns that you want displayed in the report from the Available Sources list and click Add to add them to the Selected Sources list.

6. Arrange these into the required order using the up and down arrows.
   The import file must be in the following order otherwise data will be imported into the wrong attribute, and the import will fail. More or fewer columns will also cause the import to fail:

   CM 3 to 4 layout	CM 4.0.6 layout
   UserName MACAddress HostName IPAddress Subnet DeviceName Device Port PortName PortState VTPDomain VLAN VLANType LastSeen Notes PortDuplex PortSpeed VLANId	User Name MAC Address Host Name IP Address Subnet Device Name Device Port Port Name Port State VTP Domain VLAN VLAN Type Last Seen Prefix Port Duplex Port Speed VLAN Id

   1. Specify the name of the layout as StandardTideway and enter a description.
   2. To create the StandardTideway layout, click Add.

The following methods of generating the CiscoWorks data are supported.

Generating CSV files

Generating CSV files on the CiscoWorks server:

C:\Program Files\CSCOpx\campus\bin\ut -cli -query all
   -layout StandardTideway -export c:\data.csv 
   -u user -p password

This command produces a Java stack trace. This is a known issue and can be ignored.
The file that is produced can be imported by running the following command on the BMC Atrium Discovery appliance:

$TIDEWAY/bin/tw_imp_ciscoworks --delimiter=',' 
   --username name --password password 
   --file ~/tmp/data.csv

Generating XML import files

Generating XML files on the CiscoWorks server:

C:\Program Files\CSCOpx\campus\bin\cmexport ut -u userid 
   -p password -host -layout StandardTideway

The file is written into the following directory:
C:\PROGRAM FILES\CSCOpx\files\cmexport\ut
The file that is produced can be imported with the following command on the BMC Atrium Discovery appliance:

$TIDEWAY/bin/tw_imp_ciscoworks --xml --username name 
   --password password --file ~/tmp/2006516154526ut.xml

The following attributes are imported into the data store, where they exist in the input file:
