EX3300 Switch 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 EX3300 switch default configuration:
•
Sets Ethernet switching and storm control on all interfaces
•
Sets Power over Ethernet (PoE) on all network ports of models that provide PoE
•
Enables the following protocols:
•
Internet Group Management Protocol (IGMP) snooping
•
Rapid Spanning Tree Protocol (RSTP)
•
Link Layer Discovery Protocol (LLDP)
•
Link Layer Discovery Protocol Media Endpoint Discovery (LLDP-MED)
When you commit changes to the configuration, a new configuration file is created that
becomes the active configuration. You can always revert to the factory default
configuration. See Reverting to the Default Factory Configuration for the EX Series Switch.
The following factory default configuration file is for an EX3300 switch with 24
PoE+-capable ports. This file might differ from the default configuration file on your
switch in the following ways:
•
If your model has 48 ports, the file contains more interfaces, which correspond to the
additional network ports.
•
If your model is not PoE+-capable, the file does not include the poe stanza.
