can run on the system and other SMs may run in your IB network, the priority attribute identifies the
master SM.
The integer must be between 0 and 15, with the default being 0.
1. Enter the ib sm subnet-prefix prefix priority sm-priority command.
Example
Change the Sweep Interval of a SM
The sweep interval indicates the rate (in seconds) at which the subnet manager sweeps the fabric for any
network changes.
The default is 10 seconds.
1. Enter the ib sm subnet-prefix prefix sweep-interval value command.
Example
Change the Response Timeout of a SM
The response timeout is the maximum time allowed between the port reception of a subnet management
packet and the transmission of the associated response.
The default is 2,000 microseconds.
1. Enter the ib sm subnet-prefix prefix response time-out value command.
Example
Managing Synchronization Between SMs
You can configure how database synchronization is performed between the master-Subnet Manager
(SM) and one or more standby-SMs. Refer to “Subnet Manager Hot Standby” on page 5.
Enable/Disable Database Synchronization
Database synchronization is not enabled by default.
1. Enter the ib sm db-sync subnet-prefix <prefix> enable command.
