A network device has both an SSH port and an SNMP port open. Discovery tries the SSH probe first and it fails. This triggers the SNMP probe, which…

Credential affinity is an association between a set of credentials and a device on your network. When

Discovery or Orchestration first attempts to access a device, they try all available credentials until a

valid one is found. Once a valid credential is found, it is recorded in

the dscy_credentials_affinity table, and further discovery processes rely on this information. If the

credentials are modified or changed, the process will be repeated until a valid credential is found and

updated in the same table. Credential affinity allows Discovery to use the most efficient and

successful credential for each device, and avoid unnecessary credential failures.
