Each EX8200 switch is programmed with a factory default configuration that contains the values set for each configuration parameter when a switch is shipped. The default configuration file sets values for system parameters such as the ARP aging timer, the system log, and file messages, while also enabling the LLDP protocol, the RSTP protocol, IGMP snooping, and storm control.
Page 214: Connecting And Configuring An Ex Series Switch (Cli Procedure)
Connecting and Configuring an EX Series Switch (CLI Procedure) There are two ways to connect and configure an EX Series switch: one method is through the console using the CLI and the other is using the J-Web interface. This topic describes the CLI procedure.
