When the configured keyword is used, only interfaces that have non-defaultconfigurations are displayed. Dummy linecard interfaces (created with the linecard command) are treatedlike any other physical interface.Figure 19-35 lists the possible show commands that have the configured keyword available:Command Syntax Command Mode Purposekeepalive [seconds] INTERFACE Change the default interval between keepalivemessages.FTOS(conf)# int gi 0/0FTOS(conf-if)#neg autoFTOS(conf-if-autoneg)# ?end Exit from configuration modeexit Exit from autoneg configuration modemode Specify autoneg modeno Negate a command or set its defaultsshow Show autoneg configuration informationFTOS(conf-if-autoneg)#mode ?forced-master Force port to master modeforced-slave Force port to slave modeFTOS(conf-if-autoneg)#
