Configuration Using the Web-based Utility

View Name  Displays the user-defined views. The options are as follows:

Default  Displays the default SNMP view for read and read/write views.

DefaultSuper  Displays the default SNMP view for administrator views.

Subtree IDTree  Indicates the device feature OID included or excluded in the selected SNMP view. The options to select the Subtree are as follows:

Select from List  Select the Subtree from the list provided.

Insert  Enables a Subtree not included in the Select from List field to be entered.

View Type  Indicates if the defined OID branch will be included or excluded in the selected SNMP view.

Click Add to List to add the Views configuration to the Views Table at the bottom of the screen.

SNMP > Group Profile

The Group Profile screen allows you to create SNMP groups and assign SNMP access control privileges to SNMP groups. Groups allow network managers to assign access rights to specific device features, or features aspects.

SNMP > Group Profile

Group Name  Displays the user-defined group to which access control rules are applied. The field range is up to 30 characters.

Security Model  Defines the SNMP version attached to the group. The possible field values are:

SNMPv1  SNMPv1 is defined for the group.

SNMPv2  SNMPv2 is defined for the group.

SNMPv3  SNMPv3 is defined for the group.

Security Level  Defines the security level attached to the group. Security levels apply to SNMPv3 only. The possible field values are:

No Authentication  Indicates that neither the Authentication nor the Privacy security levels are assigned to the group.

Authentication  Authenticates SNMP messages, and ensures the SNMP messages origin is authenticated.

Privacy  Encrypts SNMP messages.

Operation  Defines the group access rights. The possible field values are:

Read  The management access is restricted to read- only, and changes cannot be made to the assigned SNMP view.

Write  The management access is read-write and changes can be made to the assigned SNMP view.

Notify  Sends traps for the assigned SNMP view.

SNMP > Group Membership

The Group Membership screen provides information for assigning SNMP access control privileges to SNMP groups.

SNMP > Group Membership

User Name  Provides a user-defined local user list.

Engine ID  Indicates either the local or remote SNMP entity to which the user is connected. Changing or removing the local SNMP Engine ID deletes the SNMPv3 User Database.

Local  Indicates that the user is connected to a local SNMP entity.

Remote  Indicates that the user is connected to a remote SNMP entity. If the Engine ID is defined, remote devices receive inform messages.

Group Name  Contains a list of user-defined SNMP groups. SNMP groups are defined in the SNMP Group Profile page.

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.
