C H A P T E R 4 Advanced Configuration

Ports with IP learning

IP learning must be enabled when using IP policies. (IP learning is

 

enabled on all ports by default.) If you want to change the settings for

 

individual ports, for example if you are using protocols other that IP

 

protocols and don’t want these stations to be learned using IP rules,

 

you should:

 

1

Select VLAN Setup.

 

2

Click Advanced.

 

3

Click IP Traffic to specify which ports support IP learning.

 

4 Click OK.

 

IGMP pruning

Warning when using

It is important to be aware of problems that may arise when using

pruning

IGMP pruning and IP Multicast addresses.

 

Warning When using the IGMP pruning, IP multicast packets not

 

based on IGMP are discarded.

 

IGMP pruning can only be used in VLANs that have an IP link. En-

 

abling IGMP pruning stops Layer 2 forwarding of IP multicast pack-

 

ets in all other VLANs without IP links.

 

Only enable IGMP pruning (on this device) when it is connected be-

 

tween the device receiving the packets and an IP multicast routing de-

 

vice. Or, disable IGMP pruning (on this device) when it is connected

 

between the device transmitting the packets and an IP multicast rout-

 

ing device.

520T specifications

The Intel 520T is a well-regarded member of Intel's Xeon processor family, designed primarily for entry-level servers and workstations. Built on the 32nm manufacturing process, the 520T is based on the Nehalem microarchitecture, which has paved the way for improved performance and efficiency in data processing tasks.

One of the standout features of the Intel 520T is its energy efficiency. With a thermal design power (TDP) of just 35 watts, it provides an excellent balance between performance and power consumption. This characteristic makes it particularly suitable for environments where energy costs are a significant concern, such as in data centers or small business server applications.

Equipped with four physical cores and hyper-threading technology, the 520T allows for eight threads of execution, enabling it to handle multi-threaded workloads effectively. It operates at a base clock speed of 2.2 GHz and can achieve turbo boost frequencies up to 2.5 GHz under optimal conditions, ensuring that it provides the necessary performance for demanding applications.

The processor supports Intel's trusted execution technology and virtualization technology, maximizing both security and performance in virtualized environments. This capability allows multiple operating systems to run simultaneously on a physical server, making it an excellent fit for businesses looking to optimize their assets through virtualization.

The Intel 520T also features Intel's QuickPath Interconnect (QPI) technology, which provides a high-speed connection between the processor and other components, such as memory and storage. This feature helps minimize latency and maximizes bandwidth, enhancing overall system responsiveness.

In terms of memory support, the processor can handle up to 32 GB of DDR3 RAM, providing ample capacity for demanding applications. The 520T also supports ECC (Error-Correcting Code) memory, which is vital for mission-critical applications that require data integrity.

Security enhancements are another noteworthy aspect of the Intel 520T. With built-in security technologies, including hardware-based random number generation, the processor helps safeguard sensitive data and contributes to more secure computing environments.

Overall, the Intel 520T stands out as a robust option for users seeking an efficient server-grade processor capable of delivering strong performance while maintaining a low power profile. Its array of features, technologies, and characteristics make it a reliable choice for various computing needs.
