Step 5: Change the Admin password via the GUI, and try again.
In the verbose output do you see this error? RAKP 2 HMAC is invalid Step 4: Still cannot connect? Try to connect with this command: ipmitool -I lanplus -vvv -H -C 3 -U admin sdr Now try to connect with this command (this specifies the cipher suite to use): ipmitool -I lanplus -H -C 3 -U admin sdr
Step 3: Do you get this error? Info: cannot activate SOL payload with encryption Step 2: Try to connect with this command: ipmitool -I lanplus -H -U admin sdr Attempts to connect to LOM at an invalid IP address time out after about 10 seconds and returns this error. Note: A connection to the correct IP address, but with the wrong credentials, fails with the previous error immediately. Step 1: Can you connect using this command? ipmitool -I lanplus -H -U admin sdrĮrror: Unable to establish IPMI v2 / RMCP+ session IP Header : TTL=0x00 Flags=0x00 Precedence=0x00 TOS=0x00īMC ARP Control : ARP Responses Enabled, Gratuitous ARP Disabled For example, ipmitool lan printĪuth Type Enable : Callback : NONE MD5 PASSWORD Step 3: Can you ping the IP address of LOM? If not, run this command as root user on the applicable appliance, and verify the settings are correct. Note: For a more extensive test to confirm if the device listens on UDP port 623, use NMAP scan. IPMIPING sends two IPMI Get Channel Authentication Capabilities calls via a Get Channel Authentication Capabilities request datagram on UDP port 623 (two requests since it uses UDP and connections are not guaranteed.) However, an an alternate solution is to test if the device speaks IPMI with the IPMIPING utility. Since LOM works over a UDP port, you cannot Telnet to the LOM IP address over port 623. Step 2: Verify with the Network team that UDP port 623 is open bidirectionally, and that the routes are configured correctly. Step 1: Verify and confirm that LOM is enabled and uses a different IP address than the management interface.
LOMS WEBSITE HOW TO
The next section describes how to verify a LOM configuration and connections to the LOM interface. The connection requests might fail with these error messages: Error: Unable to establish IPMI v2 / RMCP+ session Error Info: cannot activate SOL payload with encryption You might be unable to connect to a FireSIGHT Management Center or FirePOWER Appliance with LOM. If your network is live, make sure that you understand the potential impact of any command.
All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment.
LOMS WEBSITE SOFTWARE
The information in this document is based on these hardware and software versions: Prerequisites RequirementsĬisco recommends that you have knowledge of FireSIGHT System and LOM.
LOMS WEBSITE SERIAL NUMBER
You can perform limited tasks, such as view the chassis serial number or monitor such conditions as fan speed and temperature. LOM allows you to use an out-of-band Serial over LAN (SOL) management connection in order to remotely monitor or manage appliances without logging into the web interface of the appliance. This document provides various symptoms and error messages that might appear when you configure Lights-Out-Management (LOM), and how to troubleshoot them step by step.
