SAMPLE CONFIGURATION FILE

This Appendix provides a sample configuration file that can be used with the Update Firmware and Configuration Files screen in the console program.

The configuration file is a simple text file that you create. It has two functions: to point to the location of a file on a TFTP server, and to set the IP address, subnet mask, and default gateway for the switch. The file being uploaded can be either new runtime switching software, or a switch settings file which was previously saved on the TFTP server using the Save Settings to TFTP Server option in the System Utilities menu. The IP address settings defined in the configuration file will override all other IP settings, even those defined in the settings file being uploaded. This enables the settings from one switch to be uploaded to another switch without their IP settings being the same (and thus coming into conflict).

Commands:

♦Code_type – This command tells the Switch the type of file you wish to upload to the Switch. Possible Code_types are PROM, RUNTIME, or CONFIG. This should always be the first setting.

∙PROM – PROM update file.

∙RUNTIME – Switching software update file.

∙CONFIG – Image file of switch settings created by the settings backup procedure.

♦Image_file – This command tells the Switch the complete path and filename for the file to be loaded into the Switch. For example, “e:\3225\3225prom.tfp”. Make sure double-quotes are used as in the example file below.

♦Ip_addr – This is the IP address that will be assigned to the switch. This command is included for downloading a configuration settings file to another switch. The IP address defined in this file will override the IP address in the configuration settings file, thus the switch you are downloading to can have a different IP address than the one that created the configuration settings file. An example IP address is 10.12.19.102.

♦Subnet_mask – This is the subnet mask that will be assigned to the switch. An example subnet mask is

255.128.0.0.

♦Default_gateway – This is the default gateway IP that will be assigned to the switch. An example default Gateway IP is 10.254.254.253.

♦# – Remark. When placed as the first character on a line, the entire line will be ignored by the switch. This allows items to be labeled, or unused commands to remain in the file so that the syntax will not be forgotten.

Notes about the Configuration File:

This configuration file can only contain 4 settings: Code_type, Ip_addr, Subnet_mask and Default_gateway.

Each command can only appear once in the configuration file.

DES-3225G specifications

The D-Link DES-3225GF and DES-3225G are both robust Ethernet switches designed to meet the networking needs of small to medium-sized enterprises and organizations. These devices are part of D-Link's comprehensive range of unmanaged layer 2 switches, known for their reliability and ease of use.

The DES-3225GF features a total of 25 Ethernet ports, including 24 10/100Base-TX ports and 1 Gigabit SFP slot, while the DES-3225G also comes with 25 ports but includes 24 10/100/1000 Mbps copper ports. Both models support Auto-MDI/MDI-X for seamless connection setup without the need for crossover cables, simplifying the deployment process.

One of the standout features of these switches is their wire-speed performance that enables high-speed data transfers and efficient traffic management. Each port is designed to provide non-blocking switching, which ensures that the bandwidth is fully utilized without any packet loss. The switches support IEEE 802.3x flow control, which helps to manage data flow and prevent overflow during heavy traffic periods.

The DES-3225GF and DES-3225G offer users a simple yet efficient way to expand their network. With a plug-and-play design, they require minimal configuration, allowing for quick integration into existing network infrastructures. These switches are equipped with a durable chassis, ensuring they can withstand the rigors of a busy IT environment.

Both models boast energy-efficient technologies that comply with IEEE 802.3az, which helps in reducing power consumption during periods of inactivity. By detecting link status and adjusting power accordingly, these switches contribute to a more sustainable networking solution.

In terms of form factor, the DES-3225GF and DES-3225G are rack-mounted, making them suitable for integration into standard network cabinets. This design ensures that the devices can be efficiently managed alongside other network equipment.

For management and security, the switches support features such as VLAN tagging and port security, allowing network administrators to segment traffic and protect the network from unauthorized access. With their sturdy build, innovative features, and straightforward implementation, the D-Link DES-3225GF and DES-3225G are ideal choices for organizations looking to enhance their network performance while keeping costs manageable.
