Claim:
1. A method implemented on a first switch comprising a processor coupled with a non-transient memory device for supporting state synchronization in an associated node of an associated network environment comprising a plurality of switches including the first switch, a master subnet manager (SM), and a master configuration daemon (CD) associated with the master SM, the method comprising: providing a local SM executing on the first switch; providing a local CD executing on the first switch; associating the local CD with the local SM; associating one or more subnet management agents (SMAs) of the associated node with the local SM; receiving, from the master SM via the local CD, a distributed transaction implemented by the master CD across the plurality of switches in the network environment, the distributed transaction comprising a commit command and a configuration file, wherein the configuration file includes a list of known management key (M_Key) values comprising an intended new M_Key value; storing, by the local CD, the configuration file in the non-transient memory device of the first switch; while deferring updating by the local CD the current M_Key value to the intended new M_Key value: selectively updating, by the local CD in a first transaction, the current M_Key value of the local SM with the intended new M_Key value exclusively in response to receiving an update instruction from the master CD; and discontinuing selectively using the current M_Key value by the local SM for the updating and/or setting the M_Key values of the one or more SMAs in the associated network environment responsive to the current M_Key value being updated in accordance with the commit command by the local CD from the current M_Key value to the intended new M_Key value.
