Configuration Using the Web-based Utility

Authentication Method  Use this to enable or disable Authentication between the SNMP Agent on the Switch and the SNMP Manager.

•None  Disables authentication between the SNMP Agent on the Switch and the SNMP Manager.

•MD5 Password  Enables authentication using HMAC- MD5-96 password authentication.

•SHA Password  Enables authentication using HMAC- SHA-96 password authentication.

•MD5 Key  Enables authentication using the HMAC- MD5 algorithm.

•SHA Key  Enables authentication using HMAC-SHA-96 authentication.

Password  Defines the local user password. Local user passwords can contain up to 159 characters.

Authentication Key  Defines the HMAC-MD5-96 or HMAC-SHA-96 authentication level. The authentication and privacy keys are entered to define the authentication key. If only authentication is required, 16 bytes are defined. If both privacy and authentication are required, 32 bytes are defined. Each byte in hexadecimal character strings is two hexadecimal digits. Each byte can be separated by a period or a colon.

Privacy Key  Defines the Privacy Key (LSB). If only authentication is required, 20 bytes are defined. If both privacy and authentication are required, 36 bytes are defined. Each byte in hexadecimal character strings is two hexadecimal digits. Each byte can be separated by a period or colon.

SNMP > Communities

The Communities screen is used to define SNMP communities. The Communities screen contains the following three areas: Communities, Basic Table and Advanced Table.

SNMP > Communities

SNMP Management Station  Defines the management stationIPaddressforwhichtheadvancedSNMPcommunity is defined. There are two definition options: either select the first radio button and enter the management station IP address in the field (default), or select All to include all management station IP addresses.

Community String  Defines the password used to authenticate the management station to the device.

Basic  Enables SNMP Basic mode for a selected community and contains the following fields:

Access Mode  Defines the access rights of the community. The possible field values are:

•Read Only  Management access is restricted to read- only, and changes cannot be made to the community.

•Read Write  Management access is read-write and changes can be made to the device configuration, but not to the community.

•SNMP Admin  User can access all device configuration options, and can modify the community.

View Name  Contains a list of user-defined SNMP views.

Advanced  Enables SNMP Advanced mode for a selected community and contains the following fields:

Group Name  Defines advanced SNMP communities group names.

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.
