Caveats Send documentation comments to [email protected] • CSCsq67305 Symptom: When the switch is operating in theN-port virtualization (NPV) mode, traffic may be disrupted on active Fibre Channel links if you enter the shutdown or no shutdown command on any of the NP mode uplink interfaces. The disruption also occurs if you change the interface mode of a port from F to NP or from NP to F. Traffic is disrupted for all F mode ports in the same VSAN as the NP-mode port. Workaround: Change only the interface state or interface mode on NP mode Fibre Channel interfaces during a maintenance window. • CSCso56749 Symptom: The current software does not have the ability to tag supervisor sourced frames separately depending on control or data. The frame always goes out with CoS 0. Workaround: None. • CSCso91286 Binding information specified in the Access Control System (ACS) is ignored when the Terminal Access Controller Access Control Plus (TACACS+) authentication is used to authenticate the AAA user using ACS. Symptom: When TACACS+ authentication is used to authenticate the AAA user using ACS, the Nexus 5000 Series switch ignores the user-to-role binding information specified in the ACS. You are logged in with the default role of network-operator (for new users) and network-admin. Workaround: Configure the user-to-role binding locally on the Nexus 5000 Series switch for the role binding to take effect. • CSCsq23027 Symptom: Occasional Phy loopback failure is reported in power-on self-test (POST) routines. This is a sporadic issue with front port POST routines. Occasionally, when the system comes up, ports fail the loopback test. Workaround: Reload the switch to confirm that it is a hardware defect. • CSCsq27576 Symptom: FC-SP authentication is supported only with a switch over the E/TE port. Authentication with native Fibre Channel (FC) and Fibre Channel over Ethernet (FCoE) initiator or target is not supported. Workaround: None. • CSCsq32710 Symptom: SNMP users configured with a user-defined roles cannot retrieve any Fibre Channel interfaces. Workaround: Use one of the predefined roles on the switch such as network-admin or network-operator. • CSCsq37899 Symptom: Deleting class-fcoe or class-default from an output policy map will cause show policy-map and show running-config terminal commands to be inconsistent if the priority keyword was configured for either of the classes. Workaround: The default bandwidth percentage for class-fcoe and class-default is 50 percent. Before you remove these classes from an output policy, make sure that the remaining classes in the policy map do not exceed 50 percent. Alternatively, if you want to allocate minimum bandwidth to class-fcoe or class-default, configure the bandwidth for these classes to 0 percent.
