24-port NWay Ethernet Switch User’s Guide

♦Port Lock When locked, automatic learning for all stations connected to this port will stop and entries in the Forwarding Table for all devices residing on this port will age out. The only traffic this port will allow is traffic from machines whose MAC address is manually entered in the Static Forwarding Table.

♦Broadcast Storm Rising Action This setting will be activated when Broadcast Storm Rising Threshold (below) is met. When triggered, the port can be configured to Do Nothing, Blocking or Blocking-Trap. The Do Nothing setting causes the switch to operate normally, in other words, ignore the broadcast storm condition. The Blocking setting causes the port to drop all broadcast frames, thus isolating the broadcast storm. Blocking-Trapperforms the same action as Blocking, except it also sends a trap to the designated Trap Recipient informing them of the situation. For more information on broadcast storms, please refer to the Switch Management Concepts section of this manual.

♦Broadcast Storm Rising Threshold This setting defines a ceiling for the number of broadcast packets per second on this port. Once met, the Broadcast Storm Rising Action (above) will be triggered. The assigned number should be high enough to allow normal broadcast packets (which comprise significant traffic) to be let through, while being low enough so that broadcast storms can be detected early.

♦Broadcast Storm Falling Action This setting will be activated when the Broadcast Storm Rising Threshold and then the Broadcast Storm Falling Threshold (below) is met. This setting can be configured to Do Nothing, Forwarding or Forwarding-Trap. The Do Nothing setting causes the switch to operate normally, in other words, ignore the situation. If the port had met the Broadcast Storm Rising Action criteria and started Blocking broadcast packets, it will continue doing so. The Forwarding setting causes the port to begin forwarding broadcast frames, thus removing the Blocking state imposed by the Broadcast Storm Rising Action. Forwarding-Trapperforms the same action as Forwarding, except it also sends a trap to the designated Trap Recipient informing them of the situation.

♦Broadcast Storm Falling Threshold This setting defines the number of broadcast packets per second on this port which will trigger the Broadcast Storm Falling Action (above). This threshold will only trigger an action if the Broadcast Storm Rising Threshold has first been reached. The assigned number should be high enough to allow normal broadcast packets (which comprise significant traffic) to be let through as early as possible, while being low enough so that broadcast storms are completely eliminated.

Press APPLY to let the changes take effect. If you wish these changes to be the default for the switch, return to the main menu and choose Save Changes.

STP Port State (whether the Spanning Tree Protocol is enabled or disabled on this port) and Status reflect the current conditions of the port. They are read-only fields and cannot be changed.

Configure Slot1 Module

This screen allows you to change the port state of the module in slot 1 in the case when you would like to partition a port due to excessive collision, or for observation, device repair, or security reasons. Great caution, however, must be observed when disabling a port, since all data passing through the port will be discarded by the Switch.

To change the configuration of the Slot1 module shown below:

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.
