Before NCM can access your network device configurations, you must provide login credentials for the devices you want to look at. First you define default credentials, and then you can also define network groups and add different credentials for different groups of devices. Each network group can have multiple sets of credentials, and Traverse remembers which credentials worked for each device it logs in to.
