Configuring IP parameters – Layer 3 Switches

The TFTP configuration download and update step
NOTE
This process only occurs when the client device reboots, or when Auto-Configuration has been
disabled and then re-enabled.
1. When the device reboots, or the Auto-Configuration feature has been disabled and then
re-enabled, the device uses information from the DHCP server to contact the TFTP server to
update the running-configuration file:
If the DHCP server provides a TFTP server name or IP address, the device uses this
information to request files from the TFTP server.
If the DHCP server does not provide a TFTP server name or IP address, the device requests
the configuration files from the DHCP server.
2. The device requests the configuration files from the TFTP server by asking for filenames in the
following order:
bootfile name provided by the DHCP server (if configured)
hostnameMAC-config.cfg, for example:
PowerConnect-Switch001b.ed5e.4d00-config.cfg
hostnameMAC.cfg, for example:
PowerConnect-Switch001b.ed5e.4d00.cfg
<PowerConnect >-<switch | router>.cfg (applies to Layer 2 or base Layer 3 devices), for
example:
PowerConnect-switch.cfg(FCX Layer 2)
PowerConnect-router.cfg(FCX Layer 3)
If the device is successful in contacting the TFTP server and the server has the configuration
file, the files are merged. If there is a conflict, the server file takes precedence.
If the device is unable to contact the TFTP server or if the files are not found on the server, the
TFTP part of the configuration download process ends.
