Creating hardware ACLs

Creating hardware ACLs

Hardware ACLs contain both the match criteria and the action to take on matching traffic. There are two types of hardware ACL: IP address and MAC address. These are indexed by their ID number. IP hardware ACLs have a number in the range 3000 to 3699 and MAC hardware ACLs have a number in the range 4000 to 4699.

The following table shows the available ACL ranges as displayed by the ? help, and highlights the hardware ACLs.

Number range

Description

1-99

IP standard access list

 

 

100-199

IP extended access list

 

 

1300-1999

IP standard access list (expanded range)

 

 

2000-2699

IP extended access list (expanded range)

 

 

3000-3699

Hardware IP access list

 

 

4000-4699

Hardware MAC access list

 

 

extended

Named IP extended access list

 

 

standard

Named IP standard access list

 

 

The ACLs give you the following choice of actions to take on matching traffic (see “The effects of the action keywords in ACLs” on page 6 for details).

Action parameter

Description

copy-to-cpu

Specify packets to copy to the CPU

 

 

copy-to-mirror

Specify packets to copy to the mirror port

 

 

deny

Specify packets to reject

 

 

permit

Specify packets to permit

 

 

send-to-cpu

Specify packets to send to the CPU

 

 

Creating IP hardware ACLs

IP hardware ACLs filter packets from the following IP protocols:

zIP

zICMP

zTCP

zUDP

This section describes how to create ACLs to filter packets from each of these protocols.

X900-12XT/S, x908 specifications

The Allied Telesis x908 and the SwitchBlade x900 series of network switches are cutting-edge solutions designed to address the demands of modern networking environments. These switches are known for their high performance, reliability, and robust feature sets, making them ideal for enterprise and service provider networks.

The Allied Telesis x908 series consists of modular and chassis-based systems that can accommodate a variety of network configurations. One of the main features of the x908 series is its ability to offer high scalability with support for a large number of ports. This makes it suitable for data centers and large enterprise networks where space and bandwidth optimization are critical.

In addition to scalability, the x908 series supports advanced Layer 2 and Layer 3 switching capabilities. This allows for efficient traffic management and routing, ensuring that data is delivered swiftly and reliably. The x908 also incorporates intelligent features such as Quality of Service (QoS), which prioritizes critical network traffic, ensuring that time-sensitive data—like voice and video—maintains its quality during transmission.

The SwitchBlade x900 series takes this functionality further with its innovative modular architecture. This allows organizations to configure their networks to meet specific needs by choosing from a variety of interface cards and service modules. The SwitchBlade x900 also supports advanced security features such as Access Control Lists (ACLs) and VLAN segmentation, which provide enhanced protection against unauthorized access and network threats.

Another hallmark of the x908 and SwitchBlade series is their support for high-speed Ethernet technologies, including 10G and 40G Ethernet. This enables organizations to keep pace with the increasing bandwidth demands of applications and services, particularly in cloud computing and data-intensive workloads.

Both the x908 and the SwitchBlade x900 series are designed with energy efficiency in mind, featuring power-saving technologies that reduce overall operational costs. Coupled with Allied Telesis' management tools, which provide detailed analytics and monitoring, network administrators can optimize performance and energy consumption simultaneously.

In summary, the Allied Telesis x908 and SwitchBlade x900 series offer a comprehensive suite of features, high performance, scalability, and advanced networking technologies. They represent a strategic investment for organizations looking to build resilient, efficient, and future-proof network infrastructures.
