Article ID: KB11158 KB Last Updated: 11 Aug 2020Version: 6.0
Summary:
Each EX-series 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 syslog and commit, configures PoE and Ethernet-switching on all interfaces, and enables the LLDP and RSTP protocols.
Solution:
EX 4200 Default Configuration

Each EX-series 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 syslog and commit, configures PoE and Ethernet-switching on all interfaces, and enables the LLDP (Link Layer Discovery Protocol) and RSTP (Rapid Spanning Tree Protocol) protocols.

The following factory default configuration file is for a 24-port switch. For models that have more ports, this default configuration file has more interfaces.

Note: In this example, ge-0/0/0 through ge0/0/23 are the network interface ports. Optional uplink modules provide either two 10-Gigabit Ethernet small-form factor pluggable (XFP) transceivers (xe-0/1/1/ and xe-0/1/1/) or four 1-Gigabit Ethernet small form factor pluggable (SFP) transceivers (ge-0/1/0 through ge-0/1/3) .

When you commit changes to the configuration, a new configuration file is created which becomes the active configuration. You can always revert to the factory default configuration.

This topic shows the factory default configuration file of a 24-port Ex-series switch.
