Symptom Switch is unable to form an F_Port.
Probable cause and recommended action
Regardless of the device authentication policy mode on the switch, the F_Port is disabled if the
DH-CHAP protocol fails to authenticate. If the HBA sets the FC-SP bit during FLOGI and the switch
sends a FLOGI accept with FC-SP bit set, then the switch expects the HBA to start the
AUTH_NEGOTIATE. From this point on until the AUTH_NEGOTIATE is completed, all ELS and CT
frames, except the AUTH_NEGOTIATE ELS frame, are blocked by the switch. During this time, the
Fibre Channel driver rejects all other ELS frames. The F_Port does not form until the
AUTH_NEGOTIATE is completed. It is the HBA's responsibility to send an Authentication Negotiation
ELS frame after receiving the FLOGI accept frame with the FC-SP bit set.
Protocol and certificate management
This section provides information and procedures for troubleshooting standard Fabric OS security
features such as protocol and certificate management.
Symptom Troubleshooting certificates
Probable cause and recommended action
If you receive messages in the browser or in a pop-up window when logging in to the target switch
using HTTPS, refer to
Table 13 for recommended actions you can take to correct the problem.
Gathering additional information
For security-related issues, use the following guidelines to gather additional data for your switch
support provider.
•
Perform a supportSave -n command.
•
If not sure about the problem area, collect a supportSave -n from all switches in the fabric.
•
If you think it may be related to E_Port authentication then collect a supportSave -n from both
switches of the affected E_Port.
