If the external NVIDIA® BlueField® serial connection is not available to the switch (i.e., not connected), BMC software enables access to the BlueField through an internal serial connection redirected over an IP address.
To connect to serial-over-LAN use the following IPMI command from an external server:
ipmitool -C 17 -I lanplus -H <IP address of BMC > -U ADMIN -P ADMIN sol activate
For example:
ipmitool -C 17 -I lanplus -H 10.10.10.10 -U ADMIN -P ADMIN sol activate [SOL Session operational. Use ~? for help] Poky (Yocto Project Reference Distro) 2.3.1 bluefield /dev/ttyAMA0 bluefield login:
The IPMI SOL commands are listed in the following table:
| No. | Function | Command | Description |
|---|---|---|---|
| 1 | Get SOL info | ipmitool sol info ipmitool sol info 1 | Get SOL configuration data |
| 2 | Enable SOL access | ipmitool sol set set-in-progress set-complete 1 ipmitool sol set enabled true 1 | Enable the properties to be set via set-in-progress then enable SOL access |
| 3 | Activate SOL | ipmitool -C 17 -I lanplus -U <username> -P <password> -H <ip_address> sol activate Where:
| Activate SOL access to the BlueField console |
| 4 | Deactivate SOL | ipmitool -C 17 -I lanplus -U <username> -P <password> -H <ip_address> sol deactivate | Deactivate SOL access to the BlueField console |
SOL feature can be used even if BlueField is configured to use UART1/ttyAMA1.
