Invalid Passwords - Intel S7000FC4UR Technical Product Specification

BMC Messaging Interfaces
Via hex-ASCII pair encoded IPMI commands
Via text SYS commands
The terminal mode interface supports a maximum IPMI message length of 40 bytes. The line
continuation character is supported over the serial channel in terminal mode only. The line
continuation character is supported for both hex-ASCII and text commands.
23.3.2.1 Input Restrictions
23.3.2.1.1 Maximum Input Length
The BMC supports up to 122 characters per line. The BMC stops accepting new characters and
stops echoing input when the 122-character limit is reached. However, the <ESC>,
<backspace> / <delete>, illegal, and input <newline> characters continue to be accepted and
handled after the character limit is reached.
23.3.3

Invalid Passwords

If three successive invalid Activate Session commands are received on the EMP interface, the
BMC delays 30 seconds before accepting another Activate Session command. The BMC logs
an out-of-band access password violation event to the system event log each time an invalid
Activate Session command is received.
23.4 LAN Interface
The BMC implements both the IPMI 1.5 and IPMI 2.0 messaging models. These provide out-of-
band local area network (LAN) communication between the BMC and the external world.
The BMC supports a maximum of three LAN interfaces:
Two of the LAN interfaces utilize the embedded ESB2 NICs (one channel per embedded
NIC). There is no server management traffic supported over the IO riser LAN interfaces.
One LAN interfaces utilizes an optional external NIC known as the GCM3. Use of this
NIC requires the presence of the optional Intel
card.
See the IPMI 2.0 Specification for details about the IPMI-over-LAN protocol.
Run-time determination of LAN channel capabilities can be determined both by standard IPMI
defined mechanisms and by an OEM configuration parameter that defines advanced feature
support.
23.4.1 IPMI 1.5 Messaging
The communication protocol packet format consists of IPMI requests and responses
encapsulated in an IPMI session wrapper for authentication, and wrapped in an RMCP packet,
which is wrapped in an IP/UDP packet. Although authentication is provided, no encryption is
provided, so administrating some settings, such as user passwords, through this interface is not
advised.
