•• Multiple STP  Indicates that Multiple STP is enabled on the device.

Fast Link  Indicates if Fast Link is enabled or disabled for the port or LAG. If Fast Link is enabled for a port, the port is automatically placed in the forwarding state (configurable from Spanning Tree > STP Port Settings).

Port State  Indicates if RSTP is enabled on the interface.

Point-to-Point Admin Status  Indicates if a point-to-point links are established, or permits the device to establish a point-to-point link. The possible field values are:

•• Auto  Enables automatic establishment of point-to- point links.

•• Enabled  Enables the device to establish a point-to- point link. To establish communications over a point- to-point link, the originating PPP first sends Link Control Protocol (LCP) packets to configure and test the data link. After a link is established and optional facilities are negotiated as needed by the LCP, the originating PPP sends Network Control Protocols (NCP) packets to select and configure one or more network layer protocols. When each of the chosen network layer protocols has been configured, packets from each network layer protocol can be sent over the link. The link remains configured for communications until explicit LCP or NCP packets close the link, or until some external event occurs. This is the actual switch port link type. It may differ from the administrative state.

•• Disabled  Disables point-to-point link.

Point-to-Point Oper Status  Indicates the Point-to-Point operating state.

Activate Protocol Migration Test  This option sends Link Control Protocol (LCP) packets to test if a data link is enabled.

Advanced Configuration

Spanning Tree > MSTP Properties

Multiple Spanning Tree Protocol (MSTP) provides differing load balancing scenarios. For example, while port A is blocked in one STP instance, the same port is placed in the Forwarding State in another STP instance. The MSTP Properties screen contains information for defining global MSTP settings, including region names, MSTP revisions, and maximum hops.

Spanning Tree > MSTP Properties

The MSTP Properties screen contains the following fields: Region Name  Provides a user-defined STP region name.

Revision  Defines unsigned 16-bit number that identifies the revision of the current MST configuration. The revision number is required as part of the MST configuration. The possible field range 0–65,535.

Max Hops  Indicates the total number of hops that occur in a specific region before the BPDU is discarded. Once the BPDU is discarded, the port information is aged out. The possible field range is 1–40. The field default is 20 hops.

IST Master  Identifies the Spanning Tree Master instance. The IST Master is the specified instance root.

SRW2016, SRW224G4, SRW2024, SRW2048, SRW248G4 specifications

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.
