Router(config)# line con 0
Router(config-line)# logging synchronous
This command allows all of the logging output to show up on a separate line from the configuration commands you're typing at the console. Meaning you can keep typing your commands w/o getting interrupted by a message you want to see, but don't want to be wedged in the middle of what you were trying to type. (thanks to SebaPast for being the first to set me straight!)
no ip domain-lookup
This command disables the DNS to IP domain lookup feature. This "feature" keeps you waiting at the CLI while the AP/switch/router attempts to lookup the IP address of the invalid command you entered.
