3 Configuring the Switch

Configuring a MAC ACL

Command Attributes

•Action – An ACL can contain any combination of permit or deny rules.

•Source/Destination Address Type – Use “Any” to include all possible addresses, “Host” to indicate a specific MAC address, or “MAC” to specify an address range with the Address and Bitmask fields. (Options: Any, Host, MAC; Default: Any)

•Source/Destination MAC Address – Source or destination MAC address.

•Source/Destination Bitmask – Hexidecimal mask for source or destination MAC address.

•VID – VLAN ID. (Range: 1-4094)

•Ethernet Type – This option can only be used to filter Ethernet II formatted packets. (Range: 0-65535)

A detailed listing of Ethernet protocol types can be found in RFC 1060. A few of the more common types include 0800 (IP), 0806 (ARP), 8137 (IPX).

Web – Specify the action (i.e., Permit or Deny). Specify the source and/or destination addresses. Select the address type (Any, Host, or MAC). If you select “Host,” enter a specific address (e.g., 00-90-CC-44-55-66). If you select “MAC,” enter a base address and a hexidecimal bitmask for an address range. Set any other required criteria, such as VID or Ethernet type. Then click Add.

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.
