When running IPv6 and using DHCP to assign the floating management address, a chassis failover event might cause the IP address to be changed.


Services will not be available on the floating management address as expected, and the interface will map to an unexpected IPv6 address.


Running IPv6, using DHCP for floating management address and failing over a system controller. IPv4 and static IPv6 addresses are unaffected.
