Configuration Using the Web-based Utility

SNMPv3  Enables SNMPv3 as the Notification Recipient. Either SNMPv1,2 or SNMPv3 can be enabled at any one time, but not both at the same time. If SNMPv3is enabled, the User Name and Security Level fields are enabled for configuration:

User Name  Defines the user to whom SNMP notifications are sent.

Security Level  Defines the means by which the packet is authenticated. The possible field values are:

•No Authentication  Indicates the packet is neither authenticated nor encrypted.

• Authentication  Indicates

the

packet

is

authenticated.

 

 

 

•Privacy  Indicates the packet is both authenticated and encrypted.

UDPPort  DisplaystheUDPportusedtosendnotifications. The default is 162.

Filter Name  Indicates if the SNMP filter for which the SNMP Notification filter is defined.

Timeout  Indicates the amount of time (seconds) the device waits before resending informs. The default is 15 seconds.

Retries  Indicates the amount of times the device resends an inform request. The default is 3 seconds.

Admin

The Admin tab provides access to system administration settings and tools. It includes the following screens:

Admin > User Authentication

Admin > User Authentication

The User Authentication screen is used to modify user account information. You can modify the password or user name for an existing account, or create additional accounts.

User Authentication

Authentication Type  Defines the user authentication methods. Combinations of all the authentication methods can be selected. The possible field values are:

•Local  Authenticates the user at the device level. The device checks the user name and password for authentication.

•RADIUS  Authenticates the user at the RADIUS server.

•None  Assigns no authentication method to the authentication profile.

Local User Edit

User Name  Displays the user name.

Password  The password for the specified User Name. For security purposes, the password is not displayed; instead, a“*” is displayed for each character. The password must be between 1 and 159 characters in length.

Confirm Password  Confirms the password when you change an existing password or create a new one (for a new User Name). The password entered into this field must be exactly the same as the password entered in the Password field.

Add to List/Update  The name of this button depends on the function being performed. When you create a new user name, it is Add to List; when you edit an existing password or user name, it is Update. For detailed information on its use, refer to the “Local Users Table” section below.

Local Users Table

The Local Users Table at the bottom of the screen lists all existing user names (for security purposes, passwords are not displayed). You use this table to edit or delete existing user names and/or passwords, as described below.

Create a new user name

Make sure no entry is selected in the Local Users Table. If one is selected, click Cancel. Enter the new user name in the User Name field, and the password in the Password and Confirm Password fields. Then click Add to List to add a new entry to the Local Users Table.

Change a password

Highlight the associated user name in the Local Users Table. The User Name, Password, and Confirm Password fields will then be populated for editing. Enter the new password in the Password field, then enter it again in the

SLM224G4S specifications

The Linksys SLM224G4S is a sophisticated Layer 2 managed switch designed for businesses and institutions that demand high performance, reliability, and advanced networking features. This model stands out due to its blend of robustness and manageability, making it ideal for expanding networks.

One of the primary features of the SLM224G4S is its 24 Gigabit Ethernet ports, allowing for high-speed data transfers essential for bandwidth-intensive applications. Supporting auto-negotiation, these ports can detect the capabilities of connected devices and configure themselves accordingly, ensuring optimal performance without manual intervention. With four additional shared Gigabit SFP (Small Form-factor Pluggable) ports, this switch provides flexibility in network design and enhances scalability.

The SLM224G4S supports VLAN (Virtual Local Area Network) capabilities, which can segment network traffic to improve security and performance. This is particularly useful in environments where different departments or teams require distinct network segments for operational efficiency. By implementing VLANs, organizations can enhance their network management while isolating sensitive information from potential threats.

Quality of Service (QoS) is another critical technology integrated into the SLM224G4S. It prioritizes network traffic, ensuring that critical applications receive the bandwidth they need for optimal performance. This is particularly important for VoIP and video conferencing applications, where latency and jitter can significantly impact user experience.

The switch also features advanced Layer 2 management functionalities, including SNMP (Simple Network Management Protocol), allowing IT administrators to monitor network performance and quickly troubleshoot issues. The embedded web-based management interface makes configuration straightforward, enabling quick adjustments to settings without deep networking knowledge.

Security is a paramount consideration in today’s networking landscape. The SLM224G4S provides robust security features, including port security that limits the number of MAC addresses allowed on a port, reducing the risk of unauthorized access. Moreover, it supports802.1X port-based authentication, ensuring that only authenticated devices can connect to the network.

In summary, the Linksys SLM224G4S managed switch boasts features such as 24 Gigabit Ethernet ports, VLAN support, QoS, SNMP management, and advanced security protocols. These characteristics make it an excellent choice for businesses looking to enhance their network's performance, safety, and reliability, paving the way for seamless connectivity in today’s digital age.
