The device with the highest SM priority becomes the master SM in the IB network. To configure SM
priority, perform the following steps:
1. Enter the
enable command to enter Privileged Exec mode.
Example
2. Enter the configure terminal command to enter Global Configuration mode.
Example
3. Enter the ib sm command with
• the subnet-prefix keyword
• the subnet prefix of the IB network to which the Server Switch belongs
• the priority keyword
• the priority (integer value) of the SM (where the higher the integer, the higher the priority)
to configure the priority of the SM.
Example
After you configure your subnet manager priority, connect your Server Switch Module to the outside IB
fabric. By default, the external interfaces on your Server Switch Module auto-negotiate speed with the
fabric.
NOTE: If your connections auto-negotiate to the wrong speed, bring down the port and bring it back
up. If the cable was not plugged in quickly enough, the subnet manager may incorrectly identify it.
