Advanced Configuration

VLAN Management > Port Setting

The VLAN Port Setting screen provides parameters for managing ports that are part of a VLAN. The port default VLAN ID (PVID) is configured on the VLAN Port Setting screen. All untagged packets arriving to the device are tagged by the ports PVID.

VLAN Management > Port Settings

Port  The port number included in the VLAN. Mode  Indicates the port mode. Possible values are:

•• General  The port belongs to VLANs, and each VLAN is user-defined as tagged or untagged (full 802.1Q mode).

•• Access  The port belongs to a single untagged VLAN. When a port is in Access mode, the packet types which are accepted on the port (packet type) cannot be designated. It is also not possible to enable or disable ingress filtering on an access port.

•• Trunk  The port belongs to VLANs in which all ports are tagged (except for an optional single native VLAN).

Acceptable Frame Type  Packet type accepted on the port. Possible values are:

•• Admit All  Indicates that both tagged and untagged packets are accepted on the port.

•• Admit Tag Only  Indicates that only tagged packets are accepted on the port.

PVID  Assigns a VLAN ID to untagged packets. The possible values are 2–4094. VLAN 4095 is defined as per standard and industry practice as the discard VLAN. Packets classified to the Discard VLAN are dropped.

Ingress Filtering  Enables or disables Ingress filtering on the port. Ingress filtering discards packets which do not include an ingress port.

LAG  Indicates the LAG to which the VLAN is defined.

VLAN Management > Ports to VLAN

The Ports to VLAN screen contains fields for configuring ports to a VLAN. The port default VLAN ID (PVID) is configured on the Create VLAN screen. All untagged packets arriving to the device are tagged by the ports PVID.

VLAN Management > Ports to VLAN

The Ports to VLAN screen contains a Port Table for VLAN parameters for each port. Ports are assigned VLAN membership by selecting and configuring the presented configuration options.

VLAN  The VLAN number.

Access  Indicates the port belongs to a single untagged VLAN. When a port is in Access mode, the packet types which are accepted on the port cannot be designated. Ingress filtering cannot be enabled or disabled on an access port.

Trunk  Indicates the port belongs to VLANs in which all ports are tagged, except for one port that can be untagged.

General  Indicates the port belongs to VLANs, and each VLAN is user-defined as tagged or untagged (full 802.1Q mode).

Tagged  Defines the interface as a tagged member of a VLAN. All packets forwarded by the interface are tagged. The packets contain VLAN information.

Untagged  Packets forwarded by the interface are untagged.

Forbidden  Forbidden ports are not included in the VLAN.

Exclude  Excludes the interface from the VLAN. However, the interface cannot be added to the VLAN through GVRP.

The Linksys SRW2048 is a robust Layer 2 managed switch that caters to the networking needs of small to medium-sized businesses. Designed with performance and reliability in mind, it provides features that ensure optimal network efficiency and security.

One of the standout features of the SRW2048 is its 48 10/100/1000 Mbps Gigabit Ethernet ports, enabling high-speed data transfer and seamless connectivity for various devices within the network. This makes it ideal for environments with heavy data traffic, ensuring minimal latency and high performance.

The SRW2048 also supports advanced Layer 2 management features, including VLAN (Virtual Local Area Network) support, which allows users to segment the network into smaller, manageable sections. This is crucial for improving security and performance, as it reduces unnecessary traffic and potential broadcast storms. With a VLAN configuration, businesses can group users and devices based on function or department, ensuring efficient communication within teams.

In addition to VLAN capabilities, the Linksys SRW2048 incorporates Quality of Service (QoS) features. This technology prioritizes critical network traffic, such as voice over IP (VoIP) and video conferencing, ensuring that these applications receive the bandwidth they require for optimal performance. This is particularly beneficial for businesses that rely on real-time communication tools.

The switch also enhances security through features such as IEEE 802.1X port security, which ensures that only authorized users can access the network. The SRW2048 supports access control lists (ACLs), allowing administrators to set specific permissions for users and devices, further tightening security.

Linksys has also equipped the SRW2048 with a user-friendly web-based management interface, simplifying the process of configuring and monitoring network performance. This accessible interface allows IT personnel to quickly identify issues, manage traffic, and configure settings without extensive training.

Another notable characteristic of the Linksys SRW2048 is its robust build quality and reliability. With a metal chassis and fanless design, it maintains a low acoustic footprint and ensures passive cooling, making it suitable for office environments.

Overall, the Linksys SRW2048 is a feature-rich managed switch that combines advanced networking technologies, efficient performance, and security features to meet the diverse needs of modern businesses. Its scalability, manageability, and robust construction make it a valuable addition to any network infrastructure.
