How to check SOL information and change SOL baud rate?

Purpose:

This guide is to provide a simple step-by-step guidance for users to follow on how to check SOL information and change SOL baud rate.

The OS baud rate setup refer to How to redirect OS to console ?

Target Audience:

For those engineers who has background of IPMI knowledge and how to use IPMItool and SOL (Serial Over LAN) feature.

Applicable model list:

All products which BMC with IPMI / SOL functions

Requirement:

Environment with available ipmitool utility.

Please refer to How to install IPMItool.

Method:

Step1: This guide should also be helpful for user to know How to check SOL information using IPMITOOL.

# ipmitool sol info 1
Set in progress : set-complete
Enabled : true
Force Encryption : false
Force Authentication : false
Privilege Level : ADMINISTRATOR
Character Accumulate Level (ms) : 20
Character Send Threshold : 32
Retry Count : 2
Retry Interval (ms) : 1000
Volatile Bit Rate (kbps) : 9.6
Non-Volatile Bit Rate (kbps) : 9.6
Payload Channel : 14 (0x0e)
Payload Port : 623   

Step2: If you want to change the baud rate to meet the BIOS and OS. Please follow the below command to change "Volatile Bit Rate (kbps)" and "Non-Volatile Bit Rate (kbps)"

# ipmitool -I lanplus -H <BMC IP> -U <BMC admin username> -P <BMC admin password> sol set

SOL set parameters and values:

set-in-progress set-complete | set-in-progress | commit-write
enabled true | false
force-encryption true | false
force-authentication true | false
privilege-level user | operator | admin | oem
character-accumulate-level <in 5 ms increments>
character-send-threshold N
retry-count N
retry-interval <in 10 ms increments>
non-volatile-bit-rate serial | 9.6 | 19.2 | 38.4 | 57.6 | 115.2
volatile-bit-rate serial | 9.6 | 19.2 | 38.4 | 57.6 | 115.2

# ipmitool -I lanplus -H <BMC IP> -U <BMC admin username> -P <BMC admin password> sol set non-volatile-bit-rate 115.2
# ipmitool -I lanplus -H <BMC IP> -U <BMC admin username> -P <BMC admin password> sol set volatile-bit-rate 115.2

If you're having error message called "SOL payload disabled", please have the payload enabled by following command.

# ipmitool -I lanplus -H <BMC IP> -U <BMC admin username> -P <BMC admin password> sol activate
Info: SOL payload disabled
# ipmitool -I lanplus -H <BMC IP> -U <BMC admin username> -P <BMC admin password> sol payload enable <channel> <user id>
