6.3.4 Troubleshooting
Check the client A’s IP address. If it did not receive the IP address 172.16.1.18, make sure:
1 Client A is connected to the Switch’s port 2 in VLAN 102.
2 You configured the correct VLAN ID, port number and system name for DHCP relay on both the DHCP
server and the Switch.
3 You clicked the Save link on the Switch to have your settings take effect.
6.4 How to Use Auto Configuration on the Switch
Follow the steps below to set up configurations on a DHCP server, TFTP server, and the Switch, so you
can load an auto configuration file automatically from a TFTP server when you reboot the Switch.
Note that you can set up a DHCP server and TFTP server either on the same device or different devices.
Also, make sure the Switch can communicate with the TFTP server.
Note: Steps order could vary according to different programs you use.
Note: You need to set up configurations on a DHCP server and TFTP server first to use auto
configuration.
Setting up a DHCP Server
1 Set up a dynamic IP addresses pool so the DHCP server will assign an IP address to the Switch in that
range.
2 Set up a TFTP server IP address, so the Switch will know where to load the auto configuration file.
3 Set up the filename of the auto configuration file, so the Switch will know which file to load when you
reboot the Switch.
