We recommend that you backup your startup-config file prior to performing the upgrade. If your switch has an FCoE configuration you will need to reconfigure FCoE using the new FCoE CLI. Alternatively, you can contact Cisco Customer Support for help with upgrading and converting your configuration to the new format. Downgrading to Cisco NX-OS 4.0(0)-Based Releases Your FCoE configuration will be lost on downgrade. We recommend that you backup your original configuration prior to upgrading to Cisco NX-OS Release 4.0(1a)N1(1a). The backed up startup-config can be used to restore your original configuration after a downgrade. Limitations This section describes the limitations in Nexus 5000 Series switches, Release 4.0(1a)N1(1a). • The untagged cos command is not supported in this release. • Traffic going out the Ethernet SPAN destination is always tagged. The SPAN destination can be in the access or trunk mode and frames on the SPAN source port can be tagged or untagged. Frames are always tagged internally as they travel through the system. Information about whether the frame was originally tagged or untagged, as it appeared in the SPAN source, is not preserved in the SPAN destination. The spanned traffic exiting the SPAN destination port always has the VLAN tag on it. Cisco Nexus 5000 Series Release Notes, Release 4.0(1a)N1(1a) 10 OL-16601-01
