Which command prevents the Cisco WLC CLI serial session from automatically logging out?

The command config serial timeout 0 disables the automatic logout for the serial console session on a Cisco Wireless LAN Controller (WLC). The 0 value signifies no timeout, keeping the session active indefinitely. This is useful during extended troubleshooting or configuration tasks where an active serial connection is critical. config sessions maxsessions 0 is incorrect because it relates to the maximum number of concurrent CLI sessions, not the timeout for a specific serial session. config serial timeout 9600 is incorrect because 9600 is a baud rate, not a valid timeout value for disabling the timeout. config sessions timeout 0 is incorrect because it refers to the timeout for all CLI sessions, not specifically the serial console session, and might not apply to the serial port in the same way config serial timeout does.
