Section 8. Defining the Forwarding Database

Packets addressed to destinations stored in either the Static or Dynamic databases are immediately forwarded to the port. The Dynamic MAC Address Table can be sorted by interface, VLAN, or MAC Address, whereas MAC addresses are dynamically learned as packets from sources that arrive at the device. Static addresses are configured manually.

An address becomes associated with a port by learning the port from the frame’s source address, but if a frame that is addressed to a destination MAC address is not associated with a port, that frame is flooded to all relevant VLAN ports. To prevent the bridging table from overflowing, a dynamic MAC address, from which no traffic arrives for a set period, is erased.

This section contains information for defining both static and dynamic forwarding addresses, and includes the following topics:

Configuring Static Addresses

Configuring Dynamic Forwarding Addresses

8.1 Configuring Static Addresses

The Forwarding Database Static Addresses Page contains parameters for defining the age interval on the device. To prevent static MAC addresses from being deleted when the device is reset, ensure that the port attached to the MAC address is locked. To prevent static MAC addresses from being deleted when the device is reset, ensure that the port attached to the MAC address is locked.

To define Static addressing for the forwarding database:

1.Click System > Bridging Config > Forwarding Database > Static Addresses. The Forwarding Database Static Addresses Page opens:

Figure 81: Forwarding Database Static Addresses Page

The Forwarding Database Static Addresses Page contains the following fields:

VLAN ID — Displays the VLAN ID number to which the entry refers.

MAC Address — Displays the MAC address to which the entry refers.

Interface — Displays the interface to which the entry refers:

–Port — The specific port number to which the forwarding database parameters refer.

–LAG — The specific LAG number to which the forwarding database parameters refer.

Status — Displays how the entry was created. The possible field values are:

–Secure — The MAC Address is defined for locked ports.

–Permanent — The MAC address is permanent.

–Delete on Reset — The MAC address is deleted when the device is reset.

–Delete on Timeout — The MAC address is deleted when a timeout occurs.

Remove — Removes the entry. The possible field values are:

–Checked — Removes the selected entry.

–Unchecked — Maintains the current static forwarding database.

TL-SG3109, TL-SL3428, TL-SL3452 specifications

The TP-Link TL-SL3428 is a feature-rich Ethernet switch designed for small to medium-sized business environments. It is part of TP-Link’s JetStream series, which emphasizes reliability, performance, and robust management capabilities. Built with 28 10/100/1000 Mbps ports, the TL-SL3428 provides sufficient bandwidth to support a wide range of network applications.

One of the standout features of the TL-SL3428 is its support for Layer 2 management protocols. This allows for more granular control and optimized performance across network segments. The switch supports VLAN (Virtual Local Area Network) segmentation, which enhances network security and efficiency by isolating various types of traffic. This feature is particularly useful in larger organizations where different departments or teams may require separate network environments.

The TL-SL3428 also includes advanced QoS (Quality of Service) capabilities. This functionality prioritizes traffic based on predefined rules, which ensures that critical applications receive the necessary bandwidth to function optimally. With QoS implementation, users can experience minimized latency, leading to better performance in VoIP and video conferencing applications.

In terms of redundancy and reliability, the switch also supports Link Aggregation Control Protocol (LACP), enabling multiple connections to be combined for increased bandwidth and failover support. This feature significantly enhances network resilience, ensuring minimal downtime during failures.

Power over Ethernet (PoE) support is another important characteristic of the TL-SL3428. With PoE capabilities, this switch can deliver electrical power along with data over the same Ethernet cable, simplifying installation and reducing the need for additional wiring. This is especially advantageous for IP devices like cameras, access points, and VoIP phones.

Security features are abundant in the TL-SL3428 as well. It implements port security, storm control, and DHCP snooping, all of which contribute to a secure network infrastructure. The switch’s management capabilities can be accessed through a user-friendly web interface, making it easier for IT administrators to configure and monitor network activities.

Overall, the TP-Link TL-SL3428 is an exemplary choice for businesses looking to enhance their network performance with advanced management features, security protocols, and reliability. Its combination of speed, flexibility, and manageability make it a valuable tool for any growing organization.
