Examples

Blocking all multicast traffic except one address

This example uses two interface ACLs, one with an action of permit and one with an action of deny.

Use this type of configuration when you want to discard a wide range of traffic but want to forward a subset of traffic within that range.

Consider a situation where you want to prevent the forwarding of multicast traffic in general, but wish to support an application that needs to send packets to one particular multicast address (236.5.8.213 in this example). To configure this:

1.Create an ACL to match and permit packets with the multicast destination address 236.5.8.213. To do this, enter global configuration mode and use the command:

awplus(config)#access-list 3050 permit ip any 236.5.8.213/32

2.Create an ACL to match and deny all packets with a multicast destination address. To do this, use the command:

awplus(config)#access-list 3100 deny ip any 224.0.0.0/4

3.Attach the ACLs to the port (for example, 1.0.10). You must first attach the permit ACL, then the deny ACL. To do this, use the commands:

awplus(config)#interface port1.0.10

awplus(config-if)#ip access-group 3050

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

Mirroring HTTP and SMTP traffic

This example uses two interface ACLs with actions of copy-to-mirror.

Use this type of configuration when you want to mirror a subset of the incoming traffic on a port, instead of mirroring all incoming traffic.

Consider a situation where you want to capture the HTTP (TCP port 80) and SMTP (TCP port 25) traffic coming to users who are connected to ports 1.0.1-1.0.2. To configure this:

1.Set port 1.0.20 as the mirror port. To do this, enter global configuration mode and use the commands:

awplus(config)#interface port1.0.20

awplus(config-if)#mirror interface none direction both

2.Create ACLs to match HTTP and SMTP traffic. To do this, return to global configuration mode and use the commands:

awplus(config)#access-list 3100 copy-to-mirror tcp any any eq 25

awplus(config)#access-list 3200 copy-to-mirror tcp any any eq 80

3.Attach the ACLs to ports 1.0.1-1.0.2. To do this, use the commands:

awplus(config)#interface port1.0.1-1.0.2

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

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

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.
