Priority Commands 4

map ip dscp (Global Configuration)

This command enables IP DSCP mapping (i.e., Differentiated Services Code Point mapping). Use the no form to disable IP DSCP mapping.

Syntax

[no] map ip dscp

Default Setting

Disabled

Command Mode

Global Configuration

Command Usage

•The precedence for priority mapping is IP Port, IP Precedence or IP DSCP, and default switchport priority.

•IP Precedence and IP DSCP cannot both be enabled. Enabling one of these priority types will automatically disable the other type.

Example

The following example shows how to enable IP DSCP mapping globally:

Console(config)#map ip dscp

Console(config)#

map ip dscp (Interface Configuration)

This command sets IP DSCP priority (i.e., Differentiated Services Code Point priority). Use the no form to restore the default table.

Syntax

map ip dscp dscp-value cos cos-value no map ip dscp

•dscp-value- 8-bit DSCP value. (Range: 0-63)

•cos-value- Class-of-Service value (Range: 0-7)

GSW-2692 specifications

The LevelOne GSW-2692 is an advanced Layer 2 Gigabit Ethernet switch that is designed to cater to the networking needs of both small and medium-sized enterprises. Highly regarded for its reliability and performance, the GSW-2692 offers 24 Gigabit Ethernet ports, enabling seamless and high-speed data transfers across connected devices. With its robust design and versatile capabilities, this switch has earned its place as an essential component in modern IT infrastructure.

One of the standout features of the GSW-2692 is its extensive support for advanced networking technologies. The switch includes support for IEEE 802.1Q VLAN tagging, which allows users to create separate virtual networks for improved traffic management and enhanced security. By segregating network traffic, businesses can optimize bandwidth usage and reduce congestion, contributing to overall increased network performance.

Additionally, the GSW-2692 supports Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP), ensuring loop-free network topology. This capability is crucial in larger networking environments where multiple switches are interconnected, as it prevents broadcast storms and enhances network resilience. The switch also includes features such as port mirroring, which provides administrators with the capability to monitor network traffic in real-time for troubleshooting and analysis.

Power over Ethernet (PoE) support is another significant advantage of the GSW-2692. With PoE functionality, it enables the switch to deliver electrical power along with data to connected devices such as IP cameras, VoIP phones, and wireless access points, eliminating the need for additional power sources and simplifying installations.

In terms of physical characteristics, the LevelOne GSW-2692 is designed for efficient heat dissipation and features a fanless design, which ensures silent operation. Its desktop or rack-mountable options make it flexible for various installation environments. The switch also features a web-based management interface, which simplifies the configuration and monitoring processes, allowing for intuitive management of network settings.

Overall, the LevelOne GSW-2692 stands out as a feature-rich, reliable, and high-performance networking solution that meets the demands of modern enterprises. Its combination of advanced technologies, scalability, and ease of use makes it an excellent choice for businesses looking to enhance their network infrastructure.
