24-port NWay Ethernet Switch User’s Guide

♦Root Cost Read-only object displays the cost for the path between the switch and the root bridge. If the switch is the root bridge, then the root cost is zero.

♦Root port Read-only object identifies the port (on the bridge) that offers the least path cost from the bridge to the root bridge. In the event of a network loop, data packets will pass through the root port.

♦Max Age (sec) Read-only object indicates the maximum age of STP information learned from the network (on any port) before it is discarded.

♦Forward Delay (sec) Read-only object indicates how fast any port on the bridge can change its spanning state when moving towards the forwarding state. The value determines how long the port stays in each of the listening and learning states, which precede the forwarding state.

♦Hold Time (sec) Read-only object displays the time interval during which no more than two configuration BPDUs shall be transmitted by the bridge.

♦Root Priority Read-only object displays the priority number of the root bridge of the Spanning Tree. The value is used in conjunction with the bridge MAC address to set the bridge ID, which in turn is used when determining the root bridge of a multi-bridged network. The root bridge is responsible for processing data packets when network loops occur. The smaller the number set, the higher the bridge priority is. The higher the bridge priority, the more chance the bridge has of becoming the root bridge. A bridge priority ranges from 0 to 65535, with 0 being the highest priority.

DES-3225G, DES-3225GF 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.
