Important Notes
•
When the logging event-spanning-tree interface configuration command is configured and logging
to the console is enabled, a topology change might generate a large number of logging messages,
causing high CPU usage. CPU usage can increase with the number of spanning-tree instances and
the number of interfaces configured with the logging event-spanning-tree interface configuration
command. This condition adversely affects how the switch module operates and could cause
problems such as STP convergence delay.

High CPU usage can also occur with other conditions, such as when debug messages are logged at
a high rate to the console.
a high rate to the console.
Use one of these workarounds:
–
Disable logging to the console.
–
Rate-limit logging messages to the console. (CSCsg91027)
–
Remove the logging event spanning-tree interface configuration command from the interfaces.
Device Manager Limitations
This is the device manager limitation:
When you are prompted to accept the security certificate and you click No, you only see a blank screen,
and the device manager does not start.
and the device manager does not start.
The workaround is to click Yes when you are prompted to accept the certificate. (CSCef45718)
IBM BladeCenter Advanced Management Module Limitations
This is the advanced Management Module (aMM) limitation:
When a switch module is installed in a BC-HT chassis with the ISL Interposer, the switch module
incorrectly reports that it is installed in a BC-T chassis and that it provides 8 server ports and no ISL
ports. When it is installed with the non-ISL Interposers, the switch module incorrectly reports that it is
installed in a BC-H chassis and that it provides 14 server ports.
