Device authentication
6
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.
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.
