• CSCti87650
Symptom: On a Cisco Nexus 5000, the output of the command "show interface fc<x/y>
capabilities" may indicate that "Class 2 sequential delivery" and "BB state change notification" are
supported when in fact they are not supported. The command "show interface fc<x/y> capabilities"
has to be executed.
Workaround: None.It is a display issue which should be ignored.
• CSCtj27662
Symptom: On a Cisco Nexus 5548 iIn NPV mode, TNP ports may take more than a minute to come
up the first time after a reload.Switch has to be Nexus 5548 and NPV should be enabled.
Workaround:This happens only the first time after reload. No workaround is available.
• CSCtj50241
Symptom: With ethicist NX-OS Release 5.0(2)N1(1), when a VFC interface is shut down, in
addition to the FIP Clear Virtual Link message, FCOE-LOGO is sent to the CNA. Some CNA
vendors may have problems processing the FCOE LOGO. As a result, the VFC interface may not
come back after a no-shut.
Workaround: Flap the ethernet interface that the VFC interface is bound to.
