Introduction
This release note discusses the new features, known limitations, and open caveats for Cisco UCS Virtual Interface Card Drivers, Release 2.0. It does not cover new features, known limitations, and open caveats for third party drivers.
NoteWe sometimes update the documentation after original publication. Therefore, you should also review the documentation on Cisco.com for any updates.
Use this document in conjunction with the documents listed in the Related Documentation section.
The following table shows the online change history for this document.
System Requirements
For a complete list of supported hardware and software, see the Hardware and Software Interoperability Matrix for this release located at: http://www.cisco.com/en/US/products/ps10477/prod_technical_reference_list.html
Known Limitations and Behaviors
The following known limitations are not otherwise documented:
- FcoE driver for Windows fails to perform VLAN discovery. Since there is no VLAN discovery support, we recommend that you manually configure FCoE VLANs for all adapters that support FIP,
- During iSCSI boot, only one initiator posts the iSCSI LUN to the BIOS boot menu, even if there are two iSCSI vNICs configured. For adapters configured with two iSCSI vNICs, only the iSCSI vNIC designated as Primary in the boot order will post the discovered iSCSI LUN to the BIOS boot menu and write the iBFT entry to host memory.
- Rx CRC errors might happen on interfaces that are experiencing a heavy amount of incoming traffic. Disabling the following BIOS settings reduces the number of errors:
