Caveats Send documentation comments to [email protected] • The syslog displays warnings at bootup. Although the hardware supports the 110 V input, the operating system incorrectly logs the warning message. • The show environment power command incorrectly displays the available power as a negative value. Workaround: The problem is not significant and the system operates normally with 110 V power supply input. There is no workaround to avoid the syslog message. Resolved Caveats-Cisco NX-OS Release 4.0(0)N1(2) This section lists the resolved caveats for this release. • CSCsq61505 Symptom: Problems are encountered while upgrading to Release 4.0(0)N1(2) from Releases 4.0(0)N1(1) or 4.0(0)N1(1a). Workaround: None. • 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.
