Client/Server settings



With Network Configuration Manager, you can make alterations in the basic settings like backup, discovery, syslog, report etc. By using Client/Server settings to make changes, you can do it all at once from a single platform. Let us look at the commands you can edit under the Client/Server settings tab.

Basic Settings


  • Maximum diff limit - Here you can specify the limit for the number of changes that can appear in the GUI while comparing two configurations using the Diff View. If number of line changes between two different configurations exceeds the maximum diff limit, you cannot view the changes in GUI.
  • Once the maximum diff limit is specified, you can check the "Enable auto SSH/Telnet" box to enable auto SSH and Telnet in the device summary page.
  • You can also check the "Disable Resolve DNS" box. When this is checked updation of host name for that particular IP address via DNS will be disabled.


  • Network Configuration Manager allows you to specify the number of retries that can be allowed during a schedule failure. You can choose an optimal number from the drop down.
  • Under "Scheduled backup timeout", you can provide the timeout value for the scheduled backup between 5-240 in minutes.
  • In the next tab, you can provide a value between 0-150 seconds to specify the delay in backup operation after detecting changes through syslog and for changes done from Network Configuration Manager.
