NOTE: To redirect the serial console over LAN, ensure that the SOL baud rate is identical to the baud rate of the managed
system.
Enabling supported protocol
The supported protocols are IPMI, SSH, and Telnet.
Enabling supported protocol using web interface
To enable SSH or Telnet, go to Overview > iDRAC Settings > Network > Services and select Enabled for SSH or Telnet, respectively.
To enable IPMI, go to Overview > iDRAC Settings > Network and select Enable IPMI Over LAN. Make sure that the Encryption Key
value is all zeroes or press the backspace key to clear and change the value to NULL characters.
Enabling supported protocol using RACADM
To enable the SSH or Telnet, use the following commands.
• Telnet
racadm set iDRAC.Telnet.Enable 1
• SSH
racadm set iDRAC.SSH.Enable 1
To change the SSH port
racadm set iDRAC.SSH.Port <port number>
You can use tools such as:
• IPMItool for using IPMI protocol
• Putty/OpenSSH for using SSH or Telnet protocol

The IPMI-based SOL utility and IPMItool uses RMCP+ delivered using UDP datagrams to port 623. The RMCP+ provides improved
authentication, data integrity checks, encryption, and the ability to carry multiple types of payloads while using IPMI 2.0. For more
information, see http://ipmitool.sourceforge.net/manpage.html.
The RMCP+ uses an 40-character hexadecimal string (characters 0-9, a-f, and A-F) encryption key for authentication. The default value is
a string of 40 zeros.
An RMCP+ connection to iDRAC must be encrypted using the encryption Key (Key Generator (KG)Key). You can congure the encryption
key using the iDRAC Web interface or iDRAC Settings utility.
To start SOL session using IPMItool from a management station:
NOTE
: If required, you can change the default SOL time-out at Overview > iDRAC Settings > Network > Services.
1 Install IPMITool from the Dell Systems Management Tools and Documentation DVD.
