4.28.3.2.2 Text Command Privilege Levels
The BMC supports the privilege level scheme for terminal mode text commands as specified in
Table 45.
4.28.3.3 Bridging Support
The BMC supports the optional bridging functionality described in the IPMI 2.0 specification.
4.28.4 Invalid Password Handling
If three successive invalid Activate Session commands are received on the EMP interface, the
BMC will send the hang-up sequence if in modem mode and delay 30 seconds before accepting
another Activate Session command. The BMC will also log an Out-of-band Access Password
Violation event to the system event log each time an invalid Activate Session command is
received.
4.28.5 Serial Ping Message Behavior
The BMC outputs the IPMI 2.0 specification Serial Connection Active command, or serial ping,
over the serial connection once every two seconds when basic mode is enabled in the EMP
configuration settings. However, serial ping message behavior can vary depending on the types
of operating modes enabled.
4.28.5.1 Operating Mode (Connection Mode Enable) Auto-detection
If basic mode and at least one other operating mode are enabled, and the BMC is currently
auto-detecting the operating mode, the BMC outputs the serial ping until an operating mode is
detected. If the operating mode detected is not basic mode, the serial pings are automatically
disabled. Upon connection loss, session loss, or session closure, the serial pings are
automatically re-enabled based upon the EMP configuration settings.
4.28.5.2 Terminal Mode
If terminal mode is the only operating mode enabled in the EMP configuration settings, the serial
ping is automatically disabled, regardless of the EMP configuration settings. If the EMP
configuration changes, the serial ping message behavior will automatically be re-evaluated as
necessary.
