The defaultconfiguration file sets values for system parameters such as syslog and commit; configuresPower over Ethernet (PoE), storm control, and Ethernet switching on all interfaces; andenables the LLDP and RSTP protocols.When you commit changes to the configuration, a new configuration file is created thatbecomes the active configuration. You can always revert to the factory defaultconfiguration. For instructions, see the Dell PowerConnect J-Series Ethernet SwitchComplete Software Guide for Junos OS at http://www.support.dell.com/manuals.The following factory default configuration file is for a J-EX4200 switch with 24 ports(for models that have more ports, this default configuration file has more interfaces):NOTE: In this example, ge-0/0/0 through ge-0/0/23 are the network interfaceports. Optional uplink modules provide four 1-gigabit SFP transceivers(ge-0/1/0 through ge-0/1/3). Although you can install only one uplink module,the interfaces for both are shown below.system {syslog {user * {any emergency;}file messages {any notice;authorization info;}file interactive-commands {127
