Serial Over LAN (SOL)

If the external 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:

Copy
Copied!

            
            ipmitool -C 17 -I lanplus -H <IP address of BMC > -U ADMIN -P ADMIN sol activate

For example:

Copy
Copied!

            
            ipmitool -C 17 -I lanplus -H 10.10.10.10 -U ADMIN -P ADMIN sol activate
[SOL Session operational. Use ~? for help]

2	Enable SOL access	Copy Copied! `ipmitool sol set set-in-progress set-complete 1` Copy Copied! `ipmitool sol set enabled true 1`	Enable the properties to be set via set-in-progress then enable SOL access
3	Activate SOL	Copy Copied! `ipmitool -C 17 -I lanplus -U <username> -P <password> -H <ip_address> sol activate` Where: -U – BMC username -H – BMC IP address -P – BMC password	Activate SOL access to the BlueField-2 console
4	Deactivate SOL	Copy Copied! `ipmitool -C 17 -I lanplus -U <username> -P <password> -H <ip_address> sol deactivate`	Deactivate SOL access to the BlueField-2 console

Warning

SOL feature can be used even if BlueField is configured to use UART1/ttyAMA1.
