Full QoS scenario 2: bandwidth limiting of multiple customers

create qos traff=9

set qos traff=9 maxband=5Mbps maxburst=10Kb dropbwc=yes add qos traff=9 flow=9

create qos traff=10

set qos traff=10 maxband=2Mbps maxburst=10Kb dropbwc=yes add qos traff=10 flow=10

create qos poli=6

add qos poli=6 traff=6-10 set qos port=24 poli=6

XStep 2—Giving better service to VOIP traffic

The ISP can offer to the customer a guarantee that VoIP traffic (up to a certain, relatively low, bandwidth) will be given preferential treatment.

So, for each port, VoIP traffic will be classified into its own traffic class, and directed to a high- priority egress queue.

Therefore, we need to classify VoIP traffic

create classifier=11 udpdport=5060

create classifier=12 udpdport=5061

create classifier=13 udpdport=5004 udpdmask=FFFE

create classifier=14 udpdport=16384 udpdmask=8000

The VoIP traffic needs to be associated to a traffic class that applies a strict max bandwidth, and uses the premarking DSCP map to assign the traffic to a high priority queue (and to mark the DSCP fields of the packets, for good measure).

set qos dscpmap=premarking dscp=55 newqueu=6 newdscp=55

So, the configuration for the QoS to be applied to the outgoing traffic now becomes:

set qos dscpmap=premarking dscp=55 newqueu=6 newdscp=55

create classifier=11 udpdport=5060 create classifier=12 udpdport=5061

create classifier=13 udpdport=5004 udpdmask=FFFE create classifier=14 udpdport=16384 udpdmask=8000

create qos flow=1

add qos flow=1 class=11-14

create qos traffic=1 markvalue=55 premark=usemarkvalue

set qos traffic=1 maxband=64Kbps dropbwclass3=yes maxburst=10kbytes

x900-48 series specifications

Allied Telesis X900-48 series switches are designed for high-performance networking, making them ideal for enterprise and service provider environments. This series offers advanced features and capabilities that ensure efficiency, scalability, and reliability for demanding network infrastructures.

One of the main features of the X900-48 series is its high port density. With 48 Gigabit Ethernet ports, the switch provides ample connectivity options for numerous devices, which is essential for organizations experiencing rapid growth. Additionally, it supports 10 Gigabit uplinks, allowing for high-speed connections to core networks or other switches, optimizing overall network performance.

The X900-48 series is equipped with a rich set of Layer 2 and Layer 3 features. It supports advanced routing protocols such as OSPF and BGP, enabling efficient and intelligent data routing. The inclusion of VLAN support allows for network segmentation, enhancing security and performance by isolating different traffic types. The support for IPv6 ensures that the network can accommodate future growth as more devices come online.

Quality of Service (QoS) is another critical feature of the X900-48 series. It utilizes intelligent traffic management to prioritize critical applications, ensuring a consistent user experience even during peak loads. The switch supports Power over Ethernet (PoE/PoE+), allowing it to provide power to connected devices like IP phones, cameras, and access points over the same network cable, simplifying installation and reducing costs.

Security is paramount, and the X900-48 series takes this into account with features such as IEEE 802.1X port-based authentication, Access Control Lists (ACLs), and DHCP snooping. These measures protect the network against unauthorized access and enhance data integrity.

The X900-48 series is also built with energy efficiency in mind. It complies with energy standards and integrates technologies that reduce power consumption, making it a cost-effective choice for sustainable networking without compromising performance.

Overall, the Allied Telesis X900-48 series represents a robust, versatile, and efficient switching solution tailored for modern networking demands. Its combination of high port density, Layer 2/Layer 3 functionality, advanced traffic management, and security features makes it suitable for a wide range of applications, ensuring that organizations can meet their networking challenges effectively.
