Configuration Using the Web-based Utility

Base Table

Management Station  Displays the management station IP address for which the basic SNMP community is defined.

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

Access Mode  Displays the access rights of the community.

View Name  Displays the user-defined SNMP view.

Advanced Table

Management Station  Displays the management station IP address for which the basic SNMP community is defined.

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

Group Name  Displays advanced SNMP communities group name.

SNMP > Notification Filter

The Notification Filter screen permits filtering traps based on OIDs. Each OID is linked to a device feature or a feature aspect. The Notification Filter screen also allows network managers to filter notifications.

SNMP > Notification Filter

Filter Name  Contains a list of user-defined notification filters.

New Object Identifier Subtree  Displays the OID for which notifications are sent or blocked. If a filter is attached to an OID, traps or informs are generated and sent to the trap recipients. Object IDs are selected from either the Select from List or the Object ID List. There are two configuration options:

Select from List  Select the OID from the list provided.

Object ID  Enter an OID not offered in the Select from List option.

Filter Type  Indicates whether informs or traps are sent regarding the OID to the trap recipients.

Excluded  Restricts sending OID traps or informs.

Included  Sends OID traps or informs.

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

SNMP > Notification Recipient

The Notification Recipient screen contains information for defining filters that determine whether traps are sent to specific users, and the trap type sent. SNMP notification filters provide the following services:

Identifying Management Trap Targets

Trap Filtering

Selecting Trap Generation Parameters

Providing Access Control Checks

SNMP > Notification Recipient

Recipient IP  Indicates the IP address to whom the traps are sent.

Notification Type  Defines the notification sent. The possible field values are:

Traps  Indicates traps are sent.

Informs  Indicates informs are sent.

SNMPv1,2  Enables SNMPv1,2 as the Notification Recipient. Either SNMPv1,2 or SNMPv3 can be enabled at any one time, but not both at the same time. If SNMPv1,2 is enabled, the Community String and Notification Version fields are enabled for configuration:

Community String  Identifies the community string of the trap manager.

Notification Version  Determines the trap type. The possible field values are:

SNMP V1  Indicates SNMP Version 1 traps are sent.

SNMP V2  Indicates SNMP Version 2 traps are sent.

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.
