CSCeh97137: newRoot & topologyChange Traps are not generated for Bridge Mib

Symptoms: The topology change trap is not generated while state from listening to learning & 
learning to forwarding is getting change on an interface. The new root trap is not generated while 
bridging is enabled & disabled on interfaces and while changing the mac address to make a new root.

CSCej12757: Line speed change on IOS side should be allowed

Symptoms: There are two issues:

If the speed on the serial input/output device (console) for WLC is changed from the IOS, the 
command does not take effect. However, the show line CLI will behave as if the speed has 
changed.

If you have already changed the speed on the controller side, you will be unable to session into 
the contoller, because the speed on both ends must match.

Workaround: Always use the default setting, 9600 baud.

CSCsc02741: Bootloader invalid entry creates instance where there is no option to correct the entry.

Symptoms: When in bootloader mode, if an invalid entry is entered, there is no available option to 
change the existing entry without rebooting the controller, and entering the correct entry again in 
bootloader mode.

This caveat includes the following condition when option 3 is used in the bootloader menu to update 
the corresponding values. The example below illustrates this condition:

3. Manually upgrade primary image

4. Change active boot image

5. Clear Configuration
