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.
In order 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]
