Dhcpv6 Support For Auto Ipv6 Address Assignment - Polycom realpresence 1800 Administrator's Manual

IPv6 is not supported by Lync 2010. All dial out calls from the Collaboration Server are considered Lync
2010 calls and utilize IPv4.
Dial out calls from DMA to Lync environments are considered to be dial in calls from the Collaboration
Server perspective.
The ANAT (Alternative Network Address Types) option is not applicable in Lync environments.

DHCPv6 Support for Auto IPv6 Address Assignment

DHCPv6 Auto IPv6 Addresses Assignment, as required by Lync 2013 environments is supported.
As in previous versions, SLAAC (Stateless Address Auto Configuration) continues to be supported.
System behavior can be controlled by adding the IPV6_AUTO_ADDRESS_CONFIGURATION_METHOD
System Flag and setting its value as required.
AUTO—(default) Use DHCPv6 first in case of failure use SLAAC.
SLAAC—Use SLAAC only.

System Flags for Cropping Control
Cropping occurs when the video source (endpoint) aspect ratio is different from the video cell aspect ratio
in the Polycom Video Layout.
For all endpoints other than ITP endpoints and panoramic cells the Collaboration Server calculates the
mismatch percentage between the source video aspect ratio and Polycom video layout cell aspect ratio. The
mismatch percentage is used to determine whether cropping or striping will be applied to the video cell in
the Polycom video layout.
For non-panoramic layouts, cropping and striping can be controlled by adding the
CROPPING_PERCENTAGE_THRESHOLD_GENERAL System Flag and setting its value accordingly.
For panoramic layouts, cropping and striping can be controlled by adding the
CROPPING_PERCENTAGE_THRESHOLD_PANORAMIC System Flag and setting its value accordingly.
For both System Flags:
Range: -1-100.
Default: -1
If the calculation result is less than or equal to the value of the
CROPPING_PERCENTAGE_THRESHOLD_GENERAL System Flag, cropping will be applied.
If the calculation result is greater than the value of the
CROPPING_PERCENTAGE_THRESHOLD_GENERAL System Flag, striping will be applied.
If the CROPPING_PERCENTAGE_THRESHOLD_GENERAL System Flag value is set to 0, cropping will
not be applied.
If the CROPPING_PERCENTAGE_THRESHOLD_GENERAL System Flag value is set to -1 cropping will
always be applied.
