Q033. I understand that a Cisco device is able to update firmware because there is a menu called "IOS Software Distribution". Is it possible to update firmware of other nodes except Cisco?

A033. For IOS Software Distribution feature, only firm update of Cisco device was available by default.
Firmware update of NEC WA is now available from menu "NEC WA Software Distribution".
For other devices, it is possible to update firmware by using Command Runner with job feature and creating job for firmware update.

Q034. If netLD runs job that includes wrong command, is it possible to roll the status back to where it was before running job?

A034. Yes, netLD has a feature to restore startup-config at any generations that have been backed up previously.

Q035. After applying any configuration change job, does netLD confirm that the operation has completed correctly?

A035. No. Since netLD just tries to insert registered commands to devices,
netLD operations don't include validating the configuration already inserted into the device.

Q036. Is it possible to do an operation such as running another job after running one job automatically and having confirmed previous one correctly?

A036. No, it is not possible to run operations of more than two jobs sequentially after a result analysis.
it is necessary to run those jobs one by one manually with current version.

Q037. Is it possible to run a job that was once created at fixed intervals?

A037. Yes, all jobs are to be implemented due to a schedule.
it is possible to run job that was created at fixed intervals.

Q038. Is there a limit to the number of jobs that can be added?

A038. No, theoretically there is no limit to the number of jobs.

Q039. Is it possible to run a configuration change not listed in the menu of netLD?

A039. Yes, netLD supports it by using the Command Runner feature.
*netLD may not always support interactive commands for some devices.

Q040. Do all configuration change menus support multi vendor environments?

A040. Yes, in addition, it is possible to use them without remembering different commands and grammar. For example, with the "Backup" menu, the a different command is used by each vendor, but it is possible to run backup without remembering those commands in the case of netLD.

Q041. How much configuration information can netLD save?

A041. It is possible to save as much configuration information as much as you need.

[Setting procedure]
1. Select "Settings" in the right of screen.
2. Select "Data Retention" from left menu.
3. Set "Duration to keep configuration history" to "Forever".

Q042. How does netLD the hardware information of managed nodes?

A042. netLD collects return values of commands like "show version", "show module",
and "show tech", what are called in Cisco device as H/W inventory information.

Q043. I don't want to run discovery in a network that is operating. In that case, how should I register managed devices?

A043. By selecting "Inventory" -> "Add new device", or by importing CSV file,
it is possible to register nodes manually.

Q044. When running backup to a large quantity of nodes all at once, will my network performance be affected?

A044. If bandwidth is a concern, we recommend running staggered backups. For example,if you run a configuration to automatically backup 1,00 nodes per week, consider creating 10 jobs that run backup of 100 nodes each, and stagger the running schedule.

Q045. How does netLD work internally when it runs configuration backup or change to multiple nodes at once?

A045. Basically, netLD runs various processes by CLI base.

By the way, netLD collects configurations with TFTP,
or issues "show startup-config" and "show-running" commands what are called in Cisco device to nodes,
and then saves return values as configuration information by copy and paste.

Q046. What are the required conditions to run discovery?

A046. The required conditions to run discovery are the following: ・netLD should be able to reach managed device and IP address. ・SNMP setting at node side should be valid. ・Nodes should be able to receive Telnet or SSH protocol.

Q047. How do I register managed nodes?

A047. It is possible to register nodes in these two ways:

・Run polling into LAN by IP address base, and register devices that have responded (= auto discovery).
・Enter IP address directly.
・Import CSV file.

Q048. How do I create a format to import devices?

A048. Create a format with CSV that includes the IP address and adapter ID.
You can save the inventory export Excel template from "Inventory" on the right of the screen.

Q049. Is it possible to add columns of information for registered devices?

A049. Yes, it is possible to add up to 5 custom device fields in ver.11.04.
For added fields, it is possible to set viewing restriction to login user.

[Setting procedure]
1. Select "Settings" -> "Custom Device Fields", and enter names for each custom fields.
2. Select "Settings" -> "Users" -> "Add Users", and select custom field that user can view.

Q050. How can I determine which devices have changed configuration?

A050. From ver11.04, by using "advanced search" -> "Changed: Within range",
it is possible to search devices by specifying the date of configuration backed up.

Also, it is possible to check it by making "Configuration Changes" report from "Reports" in the right of the screen.

Q051. Is it possible to restrict the viewing of devices to each login user?

A051. Yes, by making network group and making devices grouping,
viewing restriction of devices is available in a network group unit.

[Setting procedure]
1. Select "Settings" -> "Networks", and add network.
2. Select added network from "Network" in the right of the screen.
3. Add device to network.
4. Select "Settings" -> "Users" -> "Add User" -> "Networks", and select network that user can view.

Q052. I would like to receive Trap from netLD to NMS. Is it necessary to set anything in NMS?

A052. To send Trap from netLD, it is necessary to compile private MIB at NMS side. You can donwload MIB to compile from the following: http://www.logicvein.com/download/product/file/mib.zip

Q053. Does netLD have a notification feature when configuration is changed?

A053. Yes, if the new configuration is compared with last cofiguration and there is any difference additionally found,
it is possible to send SNMP trap.

[Conditions of sending SNMP trap]
1. When configuration of a device is changed (when difference is detected.).
2. When a new device is added to inventory.
3. When a device is deleted from inventory.
4. When netLD backup job fails, trap will be contained hostname, IP address, configuration file name of device.

Q054. Is it possible to change the timeout of the console screen?

A054. Yes, it is possible to change the timeout of the console screen by following these steps:

[Using version later than ver.12.03]
1. Select "Settings".
2. Select "Network Server" and change "User login idle timeout (minutes)".
3. Push "OK" button.
* As for invalid timeout, set "525,600(maximum)". It is unnecessary to reboot netLD server.

[Using version before ver.12.03]
1. Stop netLD service.
2. Open the following folder in netLD folder (default location is directly under Program Files).
Net LineDancerosgi-configjetty
3. Open "jett.win.xml" file, edit following line, and change the description "1800". (Unit: seconds)
1800
ex1) If you want to change timeout to 10 minutes, change value to "600" (10 minutes × 60 seconds).
ex2) If you want to make no timeout, change value to "0".
4. Boot netLD service.

Q055. How can I set up dynamic credential?

A055. If the credentials of managed devices are same,
it is possible to use dynamic credential to apply the same credential to managed devices by specifying the IP address range.
Also, if the static credential already has a list of devices,
it is useful to associate each device with the each credentia,l one by one.

[Example of dynamic credential setting]
In the case of setting credential to following devices:
・192.168.0.1, 192.168.2, 192.168.0.3(same credential like user and password all for three)
・10.0.0.1(different credential from others)

1. In "Credential" screen, add "Network Group" as any name.
2. Enter "192.168.0.1 - 192.168.0.3" to address specification column on the right, and add it.
3. Enter information like user and password of devices.
4. For 10.0.0.1, follow same steps above 1-3, and add credential.

Q056. Is it possible to change the configuration of multiple devices all at once?

A056. Yes, it is possible to select target devices by Ctrl or Shift key in Device view,
and then select tool from "Change" in the right of Device view and run it.
If you are unable to make changes to multiple devices all at once, the tool will be grayed out.

Q057. Is it possible to add managed devices all at once?

A057. Yes, it is possible to import devices from CSV file.
Also, it is possoble to add devices that have responded by discovery in specifying IP address range.

Q058. After I finish installing netLD, what should set up first?

A058. Basic features of netLD can be set up using the following steps: 1. Credential setting -> Enter information like password, user SNMP community of managed devices as credential. 2. Protocol setting -> Select protocol that is used to backup configuration of managed devices. 3. Add managed devices -> Add devices by manually or discovery with specifying IP address range. 4. Backup configuration -> Backup configuration of device. After following the above steps, you can use the Tool feature and the Report feature. Refer to the chapter 1.5, Initial Configuration in Net LineDancer Manual.

Q059. What can I do with the Tag feature?

A059. The Tag feature manages devices classified by groups with tags.
In Device view, it is possible to display only the devices you want to manage or apply jobs to target devices in a group unit.

[Procedures of adding Tag]
1. Click "Inventory" -> "Device Tags" in the right of device view.
2. Add new tags and click "OK" button.
3. Select devices and click "Device" -> "Associate tags" in the right of device view.
4. Select tags from a list of tag to apply.

Q060. Is it possible to check the command log that is run to devices?

A060. Yes, it is possible to get the command log by following these procedures:

[In the case of using version before ver.10.10]
1. Click "Help" -> "About" -> "Adapter Logging".
2. Select log to get by following.
・Logging debug and imortant message:
Server internal log and log of important message (credential error, device connection error, and adapter error or so)
(Save location Net LineDancerscratchlogs)
・Logging only important message (default):
Log of important message (credential error, device connection error, and adapter error or so)
(Save location Net LineDancernetld.log)
3. Run process to target device.

[In the case of using version later than ver.11.04]
1. Click "Help" -> "About" -> "Adapter Logging".
2. Enter target IP address.
ex) IP/CIDR: 172.20.0.0/16 -> Click "Enable recording of adapter operations".
* Effective time of debug is 5 minutes.
(Save location Net LineDancerscratchlogs)
3. Run process to target device.

Q119. How can I apply the configuration I wrote directly?

A119. The draft configuration feature, added to Net LineDancer v13.08, can be used to push the config you directly edited on the devices.

Q120. Can I register the memo format frequently used?

A120. On v13.08, the memo template feature is added. This memo is also available for the configuration or draft configuration, which are also added on this version. For each type of memo (devices, configuration, draft configuration), one template can be created.

Q121. Can I attach memos in the inventory?

A121. Yes, you can attach memos to the devices in the inventory. On v13.08, you can also attach it for the config and draft config.* * Draft configuration is added on v13.08, where users can edit a configuration directly and push it on the devices.
