To configure SNTP authentication:

1.Click System > System Info > SNTP > Authentication. The SNTP Authentication Page opens:

Figure 13: SNTP Authentication Page

The SNTP Authentication Page contains the following fields:

Enable SNTP Authentication — Indicates if authenticating an SNTP session between the device and an SNTP server is enabled on the device. The possible field values are:

–Checked — Authenticates SNTP sessions between the device and SNTP server.

–Unchecked — Disables authenticating SNTP sessions between the device and SNTP server.

Encryption Key ID — Indicates if the encryption key identification is used to authenticate the SNTP server and device. The field value is up to 4294967295.

Authentication Key — Indicates the key used for authentication.

Trusted Key — Indicates the encryption key used (Unicast/Anycast) or elected (Broadcast) to authenticate the SNTP server.

Remove — Removes Encryption Key IDs. The possible field values are:

–Checked — Removes the selected Encryption Key ID.

–Unchecked — Maintains the Encryption Key IDs. This is the default value.

2.Check the Enable SNTP Authentication checkbox.

3.Click . SNTP Authentication is defined, and the device is updated.

To define SNTP authentication parameters:

1.Click . The Add SNTP Authentication Page opens:

Figure 14: Add SNTP Authentication Page

2.Define the Encryption Key ID, Authentication Key, and

Trusted Key fields.

3.Click . The SNTP Authentication Key is added, and the device is updated.

3.2.4 Defining SNTP Servers

The SNTP Servers Page contains information for enabling SNTP servers, as well as adding new SNTP servers. In addition, the SNTP Servers Page enables the device to request and accept SNTP server traffic.

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.
