Note: Select Manage via Hostname in a DNS / DHCP environment. For
this to be effective, however, the association between hostname and
the correct IP address for the discovered equipment must be
accurate.
2. New / Edit Authentication. You can select authentication(s) to go with a selected discovery
target with the checkboxes that appear in the list of existing authentications in the Select
Authentication panel. In addition, you can Add or Edit authentications to associate with that
target. When you Add an authentication, or Edit an existing one, an authentication editor
opens in the bottom of the screen.
Select or create the Name for the authentication, and select the Type from the pick list.
See the NMS200 User Guide for details about what to expect for the different types.
Note: Ensure the type selected matches the management interface on the
equipment you want to discovery. You can use some single
authentications in different types, for example: Telnet and SSH.
Notice that you can also alter the Timeout, Retries, and Port for the authentication at the
bottom of this screen, so the authentication fits with your network’s connection speed.
3. Select Devices for Discovery. Click Apply to accept your authentication.
