14.1 Configuring Port Mirroring

Port mirroring monitors and mirrors network traffic by forwarding copies of incoming and outgoing packets from one port to a monitoring port. Port mirroring can be used as a diagnostic tool as well as a debugging feature. Port mirroring also enables switch performance monitoring.

Network administrators can configure port mirroring by selecting a specific port from which to copy all packets, and other ports to which the packets copied.

To perform port mirroring diagnostics:

1.Click System > Maintenance > Diagnostics > Port Mirroring. The Port Mirroring Page opens:

Figure 127: Port Mirroring Page

The Port Mirroring Page contains the following fields:

Destination Port — Defines the port number to which port traffic is copied.

Transmit Packets — Defines the how the packets are mirrored. The possible field values are:

–Untagged — Mirrors packets as untagged VLAN packets. This is the default value.

–Tagged — Mirrors packets as tagged VLAN packets.

Source Port — Indicates the port from which the packets are mirrored.

Type — Indicates the port mode configuration for port mirroring. The possible field values are:

–RX — Defines the port mirroring on receiving ports.

–TX — Defines the port mirroring on transmitting ports.

–Both — Defines the port mirroring on both receiving and transmitting ports. This is the default value.

Remove — Removes the port mirroring session. The possible field values are:

–Checked — Removes the selected port mirroring sessions.

–Unchecked — Maintains the port mirroring session.

2. Click . The Add Port Mirroring Page opens:

Figure 128: Add Port Mirroring Page

3.Select a port in the Source Port field.

4.Select a port type in the Type field.

5.Click . The port mirroring session is defined, and the device is updated.

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.
