The subnet manager • Discovers the subnet topology and dynamically updates it at a specified sweep interval that you specify with the interval variable. • Assigns the local identifiers (LIDs), global identifier (GID) subnet prefix, and partition keys for each HCA port. • Assigns the LIDs, GID subnet prefix, and forwarding databases for each switch on the subnet. • Maintains the end-node and service databases of the subnet, providing a GUID to LID/GID resolution service as well as a services directory. One subnet manager administers the InfiniBand fabric. All InfiniBand hosts run on this one subnet. The subnet manager loads upon bootup. Each node in the fabric has a subnet management agent (SMA) to shuttle communication requests between the node and the subnet manager. Communication between the subnet manager and the subnet management agent uses the common management datagram (MAD) message structure. Only multicast and p_Key configuration attributes are synchronized between master and standby SMs. If other attributes are changed, they must be manually issued at the standby SMs as well. If, in the future, there is a change in the location of standby SMs, run the command show config to list all of the configuration changes previously made at the master SM. Then replay the configuration changes at the new standby SMs. Regarding Partitions: Partitions are created, and then ports are added to those partitions to enforce isolation. Examples The following example creates a multicast group: SFS-7000P(config)# ib sm subnet-prefix fe:80:00:00:00:00:00:00 multicast mgid fe:80:00:00:00:00:00:00:00:00:00:00:00:00:00:00 Related Commands ib-agent ib sm db-sync ib sm show ib sm configuration OL-9163-02 Cisco SFS 7000 Series Product Family Command Reference Guide 4-13
