SYSCFG Questions
Q: Can I use the SYSCFG utility to configure Point-to-Point Protocol (PPP)
over the serial port to access my RAC?
A: No. The Baseboard Management Controller (BMC) firmware does not
support PPP configurations for the serial port.
Q: The SYSCFG utility --lancfgparams option has suboptions that configure
the IP address, Gateway, and Subnet Mask for the system BMC. There is also
a MAC address. Are these the same as the managed system’s operating system
network parameters?
A: No. The BMC has its own IP address, Gateway, Subnet Mask, and MAC
address values.
Q: What is the minimum configuration needed to support BMC Platform
Event Filtering?
A: You must enable LAN-channel access pefalerting and ensure that you set
the BMC IP address and Gateway values for alerting.
Q: I loaded the factory defaults for my system’s BMC. Then, I enabled BMC
user ID 3. What is the username for this user ID?
A: The default username for user IDs 3 to 10 is NULL.
Q: Can I use this NULL username to remotely log in to a system’s BMC?
A: No. Remote login using a NULL username is not allowed. It is
recommended that you always provide a non-null, valid username for the user
ID when you enable a BMC user ID.
