6 Device authentication Symptom Unable to log into the boot PROM. Probable cause and recommended action To recover a lost boot PROM password, contact your switch service provider. You must have previously set a recovery string to recover the boot PROM password. This does not work on lost or forgotten passwords in the account database. Password recovery options Table 12 describes the options available when one or more types of passwords are lost. TABLE 12 Topic Password recovery options Solution If all the passwords are forgotten, what is the password recovery mechanism? Are these procedures non-disruptive recovery procedures? Contact your switch service provider. A non-disruptive procedure is available. If a user has only the root password, what is the password recovery mechanism? Use passwd command to set other passwords. Use passwdDefault command to set all passwords to default. How to recover boot PROM password? Contact your switch service provider and provide the recovery string. How do I recover a user, admin, or factory password? Refer to "Passwords" on page 61 for more information on recovering these passwords. Symptom User is unable to modify switch settings. Probable cause and recommended action The most common error when managing user accounts is not setting up the default Admin Domain and access control list or role-based access control (RBAC). Errors such as a user not being able to run a command or modify switch settings are usually related to what role the user has been assigned. Device authentication Symptom Switch is unable to authenticate device. Probable cause and recommended action When the device authentication policy is set to ON, the switch expects a FLOGI with the FC-SP bit set. If this bit is not set, the switch rejects the FLOGI with reason LS_LOGICAL_ERROR (0x03), in the switch log with the explanation of "Authentication Required"(0x48), and disables the port. Set the device authentication policy mode on the switch to ON. 62 Fabric OS Troubleshooting and Diagnostics Guide 53-1002751-01
