2.
After the new switch acquires an IP address, the autoinstallation process on the switch
attempts to download a configuration file in the following ways:
a.
If the DHCP server specifies the host-specific configuration file hostname .conf , the
switch uses that filename in the TFTP server request. The autoinstallation process
on the new switch makes three unicast TFTP requests for
hostname .conf
. If these
attempts fail, the switch broadcasts three requests to any available TFTP server
for the file.
b.
If the new switch does not locate a
hostname .conf
file, the autoinstallation process
sends three unicast TFTP requests for a
network.conf
file that contains the switch’s
hostname-to-IP-address mapping information. If these attempts fail, the switch
broadcasts three requests to any available TFTP server for the file.
c.
If the switch fails to find a
network.conf
file that contains a hostname entry for the
switch, the autoinstallation process sends out a DNS request and attempts to
resolve the new switch's IP address to a hostname.
d.
If the new switch determines its hostname, it sends a TFTP request for the
hostname .conf
file.
e.
If the new switch is unable to map its IP address to a hostname, it sends TFTP
requests for the default configuration file
switch.conf . The TFTP request procedure
is the same as for the network.conf file.
3.
After the new switch locates a configuration file on a TFTP server, the autoinstallation
process downloads the file, installs the file on the switch, and commits the
configuration.

J-EX4200 Default Configuration
Each J-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
Power over Ethernet (PoE), storm control, and Ethernet switching on all interfaces; and
enables the LLDP and RSTP protocols.
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
