Adding and Removing Devices

To be able to work with a device, you should register it in the program. In the process of its registration, the device is added to the MIB tree. To make working with a lot of devices more comfortable, you can divide them into groups.

You can create a new group using the 'Actions->Add new group' command from the main menu. It will open a dialog box that you should use to enter a name for the new group, a comment and also select one of the existing groups as its parent one. To remove a group, select it in the tree and select the 'Actions->Remove selected item' command from the main menu. The program will ask for your confirmation. If you confirm it, the group with all devices and subgroups in it will be removed.

To add a new device, you should select the 'Actions->Register new device' command from the menu. This will open the 'Device Properties' dialog box with two tabs in it. On the General tab, you should specify the name of the device and either its IP address or its domain name. Besides, you should select the group the device will be added to. The SNMP tab contains the protocol settings that are used for connecting to the device:

• SNMP Port - the number of the port used for connecting to the device. The default is 161.
• Use Protocol (protocol version) - the version of the SNMP protocol used for connecting to the device.
• Read Community - the community string used for reading SNMP parameters from the device.
• Write Community - the community string used for writing SNMP parameters.
• Security Name - authentication name (only when SNMP version 3 is used).
• Security Level - the security level of SNMP version 3.
• Authentication - the algorithm of authentication in SNMP version 3 (MD5 or SHA).
• Auth Password - the password for authentication in SNMP version 3.
• Priv Password - the password for encrypting transmitted data in SNMP version 3.
• Engine ID - the ID of the SNMP engine for SNMP version 3.

After you specify the parameters of the device, click OK. The device with the specified parameters will be added to the tree. Later, you will be able to change these parameters by selecting the device in the tree and selecting either the 'Action->Properties' command from the main menu or the 'Properties' command from the context menu.

To remove a device, you should select it and select the 'Actions->Remove selected item' command from the main menu.
