Global credentials lists
NetIM maintains lists of credentials that are used to access devices. One list contains SNMP v1/v2c community strings. Another contains SNMP v3 credentials. A third list contains command-line interface (CLI) login credentials (usernames, passwords, and privileged passwords). These lists are used for the following purposes:
• The Add/Discover Devices wizard uses these credentials to prepopulate lists on the Community Strings, SNMP v3 Credentials, and Credentials pages so that you do not need to reenter information that has been used before.
• Device autodiscovery uses SNMP v1/v2c community strings and SNMP v3 credentials to discover new devices, and CLI login credentials to determine the appropriate mechanism, login, and device driver for devices.
• AppNetwork Path Analysis uses CLI login credentials to attempt to log in to devices that are not in the device list.
Entries can be added to the global credentials lists in two ways:
•
Add/Discover Devices wizard. Any items you enter on the Community Strings page, SNMP v3 Credentials page, or Credentials page are automatically added to the corresponding global list. Items subtracted are only removed for that run of the Add/Discover Devices wizard.
•
Device Autodiscovery. All items entered in this method are added to the global credentials list. Similarly, items subtracted are removed from the global credentials list.
When you remove an item from a list on the Community Strings page or Credentials page in the Add/Discover Devices wizard, the removed item will not be used for that discovery process. However, it will remain in the global credentials list.
