Resolved Caveats
This section lists caveats that are resolved but that may have been open in previous releases.
Defects are listed in order of severity. Because defect status continually changes, be aware that this document reflects a snapshot of the defects that were resolved at the time this report was compiled. For an updated view of resolved defects, access the Bug Toolkit (see the "Using Bug Toolkit" section).
Closed Caveats
These caveats have been closed, which means that Cisco acknowledges that there is a problem but chooses not to fix it. See the "Using Bug Toolkit" section for information about accessing these caveats.

MCU failed to reboot.
Workaround: Reboot the MCU manually.
Troubleshooting
Firefox Support
When using the Firefox web browser to access the CUVC MCU, a rare access error might be seen. Logging in again to the CUVC MCU resolves it.
E-20 Operation
E-20 works incorrectly towards the MCU. There is a workaround on Cisco Unified Communications Manager. A configuration note has been included in CSCtn47361.

Omissions
Setting the Maximum MTU Size on the CUVC
The CUVC's maximum MTU size determines the largest size of the data packets that can be sent by the CUVC. If the size of the data packet is larger than the maximum allowed by your network routers, the packet is split. This fragmentation can significantly impact video quality. Therefore it is important to set the MTU size of the CUVC to be in step with the router size. For example, if the CUVC's MTU size is set to 1500 while the network routers are configured to 1360 packet sizes, you can improve video quality by setting the CUVC's MTU size to 1360 to match the routers.
