When the management IP address changes (either as a result of enabling mgmt-dhcp, or the leased address changing), the system does not synchronize this updated address to other devices in the failover device group / trust domain. (That is, the system does not trigger an update to the device_trust_group.)
This can cause disruption in an HA environment. The sod process discards any HA heartbeat traffic it receives (e.g., traffic over the self IP addresses) that does not contain a 'known' cluster_mgmt_ip.
This occurs on HA configurations.
None.
Enabling DHCP on the management interface no longer causes nodes in a DSC to get out of sync or otherwise work unexpectedly.
