When the switch is in VTP client mode, all broadcast traffic is blocked for a given VLAN when a 
vtp prune event is immediately followed by a re-join event. ARP does not complete and 
consequently MAC addresses on upstream devices are not learned.

The workaround is to set the VTP mode to transparent.

In certain boot sequences, the BOOT variable is removed from the switch. At the next reboot 
attempt, the reboot fails, and the switch remains in the bootloader prompt. 

The workaround is to: 

Boot the switch with boot flash:file_name command.

or

Set the BOOT variable explicitly in the bootloader using BOOT=flash:file_name and, then boot 
the switch using boot command.

When the client sends a new association for a different SSID and fast SSID changing is disabled, the 
client entry in the controller connection table is cleared before the client is added to the new SSID. This 
means that the controller enforces a delay before clients are allowed to move to a new SSID. When fast 
SSID changing is enabled, there is no delay, and clients move more quickly from one SSID to another. 

Beginning in privileged EXEC mode, follow these steps to configure fast SSID changing: 

Controller# configure terminal

Enters global configuration mode.
