Advanced Configuration

Use the Policy Settings button to open the Policy Name screen.

Advanced Mode > Policy Name

Advanced Mode > Policy Name

Policy Name  Defines a new Policy name.

Add to List  The Add to List button lets you add the policy to the Policy Name table.

Advanced Mode > New Class Map

Advanced Mode > New Class Map

Class Map Name  Defines a new Class Map name.

Preferred ACL  Indicates if packets are first matched to an IP-based ACL or a MAC based ACL. The possible field values are:

•• IP Based ACLs  Matches packets to IP-based ACLs first, then matches packets to MAC based ACLs.

•• MAC Based ACLs  Matches packets to MAC-based ACLs first, then matches packets to IP-based ACLs.

IP ACL  Matches packets to IP-based ACLs first, then matches packets to MAC-based ACLs.

Match  Criteria used to match IP addresses and/or MAC addresses with an ACL’s address. The possible field values are:

•• And  Both the MAC-based and the IP-based ACL must match a packet.

•• Or  Either the MAC-based or the IP-based ACL must match a packet.

MAC ACL  Matches packets to MAC-based ACLs first, then matches packets to IP-based ACLs.

Advanced Mode > New Aggregate Policer

Advanced Mode > New Aggregate Policer

Aggregate Policer Name  Enter a name in this field.

Ingress Committed Information Rate (CIR)  Defines the CIR in bits per second. This field is only relevant when the Police value is Single.

Ingress Committed Burst Size (CBS)  Defines the CBS in bytes per second. This field is only relevant when the Police value is Single.

Exceed Action  Action assigned to incoming packets exceeding the CIR. This field is only relevant when the Police value is Single. Possible values are:

•• Drop  Drops packets exceeding the defined CIR value.

•• RemarkDSCP(OutofProfileDSCP)  Remarks packet’s DSCP values exceeding the defined CIR value.

•• None  Forwards packets exceeding the defined CIR value.

Spanning Tree

Spanning Tree Protocol (STP) provides tree topography for any arrangement of bridges. STP also provides one path between end stations on a network, eliminating loops.

Loops occur when alternate routes exist between hosts. Loops in an extended network can cause bridges to forward traffic indefinitely, resulting in increased traffic and reducing network efficiency.

The device supports the following Spanning Tree versions:

•• Classic STP  Provides a single path between end stations, avoiding and eliminating loops.

•• Rapid STP  Detects and uses network topologies that provide faster convergence of the spanning tree, without creating forwarding loops.

•• Multiple STP  Provides full connectivity for packets allocated to any VLAN. Multiple STP is based on the RSTP. In addition, Multiple STP transmits packets assigned to different VLANs through different MST regions. MST regions act as a single bridge.

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.
