Abstract

A system and method can support network management in a network environment. The network environment can include a plurality of configuration daemons (CDs), wherein a master CD is an active CD on a switch with a master subnet manager (SM). The master CD operates to perform consistency check on one or more states associated with one or more peer CDs in the network environment, and replicate a configuration file to the one or more peer CDs, wherein the configuration file includes at least one management key (M_Key) value.

Claims

1. A method for supporting network management in a network environment, comprising:

providing a plurality of configuration daemons (CDs) in the network environment, wherein a master CD is an active CD on a switch with a master subnet manager(SM);

performing, via the master CD, consistency check on one or more states associated with one or more peer CDs in the network environment, wherein each said peer CD is an active CD on a switch with a standby SM; and

replicating a configuration file to the one or more peer CDs, wherein the configuration file includes at least one management key (M_Key) value.

2. The method according to claim 1, further comprising:

instructing, via the master CD, the one or more peer CDs to update the standby SMs with the at least one M_Key value.

3. The method according to claim 1, further comprising:

determining an order for replicating the configuration file to the one or more peer CDs based on a type of a transaction.

4. The method according to claim 3, further comprising:

using the configuration file to first update one or more known lists of M_Key values on the master SM, when the transaction is an add-only transaction.

5. The method according to claim 3, further comprising:

using the M_Key configuration file to first update one or more known lists of M_Key values on the one or more standby SMs, when the transaction is not an add-only transaction.

6. The method according to claim 1, further comprising:

allowing the one or more states to include

availability of the one or more peer CDs,

compatible implementation/protocol version,

correct current daemon run-time state, and

correct current configuration state/version on the one or more peer CDs.

7. The method according to claim 1, further comprising:

verifying consistent encryption password for each CD prior to initiating a transaction.

8. The method according to claim 1, further comprising:

prohibiting changing a new current M_Key value and deleting an old current M_Key value in a same transaction.

9. The method according to claim 1, further comprising:

ensuring that the master SM has a known M_Key list not shorter than any M_Key list maintained by a standby SM instance.

10. The method according to claim 9, further comprising:

initiating a commit operation on the master CD.

11. A system for supporting network management in a network environment, comprising:

one or more microprocessors;

a master configuration daemon (CD) running on the one or more microprocessors, wherein the master CD is an active CD on a switch with a master subnet manager(SM),

wherein the master CD operates to

perform consistency check on one or more states associated with one or more peer CDs in the network environment, wherein each said peer CD is an active CD on a switch with a standby SM; and

replicate a configuration file to the one or more peer CDs, wherein the configuration file includes at least one management key (M_Key) value.

12. The system according to claim 11, wherein:

the master CD operates to instruct the one or more peer CDs to update the standby SMs with the at least one M_Key value.

13. The system according to claim 11, wherein:

an order for replicating the configuration file to the one or more peer CDs can be determined based on a type of a transaction.

14. The system according to claim 13, wherein:

the master CD operates to use the configuration file to first update one or more known lists of M_Key values on the master SM, when the transaction is an add-only transaction.

15. The system according to claim 13, wherein:

the master CD operates to use the M_Key configuration file to first update one or more known lists of M_Key values on the one or more standby SMs, when the transaction is not an add-only transaction.

16. The system according to claim 11, wherein:

the one or more states include

availability of the one or more peer CDs,

compatible implementation/protocol version,

correct current daemon run-time state, and

correct current configuration state/version on the one or more peer CDs.

17. The system according to claim 11, wherein:

consistent encryption password is verified for each CD prior to initiating a transaction.

18. The system according to claim 11, wherein:

an operation to change a new current M_Key value and an operation to delete an old current M_Key value is prohibited in a same transaction.

19. The system according to claim 11, wherein:

the master CD operates to ensure that the master SM has a known M_Key list not shorter than any M_Key list maintained by a standby SM instance.

20. A non-transitory machine readable storage medium having instructions stored thereon that when executed cause a system to perform the steps comprising:

providing a plurality of configuration daemons (CDs) in a network environment, wherein a master CD is an active CD on a switch with a master subnet manager(SM);

performing, via the master CD, consistency check on one or more states associated with one or more peer CDs in the network environment, wherein each said peer CD is an active CD on a switch with a standby SM; and

replicating a configuration file to the one or more peer CDs, wherein the configuration file includes at least one management key (M_Key) value.
