Configuring IP parameters – Layer 3 Switches
• For a Layer 3 device, one leased address is granted (per device) to the interface that first
receives a response from the DHCP server.
2. If auto-update is enabled, the TFTP flash image is downloaded and updated. The device
compares the filename of the requested flash image with the image stored in flash. If the
filenames are different, then the device will download the new image from a TFTP server, write
the downloaded image to flash, then reload the device.
3. In the final step, TFTP configuration download and update, the device downloads a
configuration file from a TFTP server and saves it as the running configuration.
Figure 8 shows how DHCP Client-Based Auto Configuration works.
