Making filters by applying hardware ACLs to ports

 

Making filters by applying hardware ACLs to ports

 

You can create a filter by simply applying one or more ACLs to a port, as long as you can

 

select the matching traffic through hardware ACL keywords, as described above.

 

ACLs can be applied to switch ports and static channel groups. To apply an ACL to a dynamic

 

(LACP) channel group, apply the ACL to all ports that can be in the channel group.

 

The hardware filters act on incoming traffic, so apply them to the ingress ports.

Attaching

To apply ACLs to ports, enter interface mode for the port or ports you want to attach the

ACLs

ACL to, and then use one of the following commands:

 

For IP hardware ACLs:

 

ip access-group <ip-acl-number>

 

For MAC hardware ACLs:

 

mac access-group <mac-acl-number>

 

If you have multiple ACLs on a port, attach them to the port in the order in which you want

 

the switch to check them—see“The logic of the operation of the hardware filters” on

 

page 13. You can alternate IP and MAC ACLs, like in the following example:

 

awplus(config-if)#ip access-group 3200

 

awplus(config-if)#ip access-group 3100

 

awplus(config-if)#mac access-group 4300

 

awplus(config-if)#ip access-group 3150

 

awplus(config-if)#mac access-group 4350

Viewing port

To see a list of the ACLs that are directly attached to a port, use the following command:

information

awplus#show interface <range> access-group

 

Changing

It is not possible to change the order of ACLs once you have attached them to a port.

ACL order

Instead, remove ACLs from the port by entering interface mode for the port and using the

 

commands:

 

no ip access-group <ip-acl-number>

 

no mac access-group <mac-acl-number>

 

Then re-enter them in the desired order.

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.
