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]   Poky (Yocto Project Reference Distro)   2.3.1 bluefield /dev/ttyAMA0   bluefield login:
