Keyword

 

Interface Type

 

 

 

tunnel

 

Tunnel interface; a virtual interface. The number is the number of the tunnel

 

 

interface that you want to create or configure. There is no limit on the number

 

 

of tunnel interfaces you can create.

 

 

 

vg-anylan

 

100VG-AnyLAN port adapter.

 

 

 

Configuring a Proxy with ASR

To enable ASR on the proxy, start the proxy and then define the H.323 name, zone, and QoS parameters on the loopback interface. Next, determine which interface will be used to route the H.323 traffic and configure ASR on it. The ASR interface and all other interfaces must be separated so that routing information never travels from one to the other. There are two different ways to separate the ASR interface and all other interfaces:

•Use one type of routing protocol on the ASR interface and another on all the non-ASR interfaces. Include the loopback subnet in both routing domains.

•Set up two different autonomous systems, one that contains the ASR network and the loopback network and another that contains the other non-ASR networks and loopback network.

To ensure that the ASR interface and all other interfaces never route packets between each other, configure an access control list. (The proxy traffic will be routed specially because it is always addressed to the loopback interface first and then translated by the proxy subsystem.)

To start the proxy with ASR enabled on the proxy using one type of routing protocol on the ASR interface and another on all of the non-ASR interfaces, and with the loopback subnet included in both routing domains, use the following commands beginning in global configuration mode:

 

Command

Purpose

Step 1

 

 

Router(config)# proxy h323

Starts the proxy.

Step 2

 

 

Router(config)# interface type number [name-tag]

Enters loopback interface configuration mode.

 

 

For an explanation of the arguments, see Step 2 in the

 

 

“Configuring a Proxy Without ASR” configuration

 

 

task table.

 

 

To configure a proxy with ASR enabled on the proxy

 

 

using one type of routing protocol, the type argument

 

 

is loopback. The loopback type specifies the

 

 

software-only loopback interface that emulates an

 

 

interface that is always up. It is a virtual interface

 

 

supported on all platforms. The number argument is

 

 

the number of the loopback interface that you want to

 

 

create or configure. There is no limit on the number

 

 

of loopback interfaces that you can create.

VC-289 specifications

Cisco Systems has long been a leader in networking technology, and among its diverse range of products is the VC-289. Designed specifically for enhanced performance in high-demand environments, the VC-289 serves a critical role in supporting the modern networking infrastructure.

One of the standout features of the VC-289 is its scalability. The device is engineered to easily accommodate expanded workloads, ensuring that organizations can grow without the need for frequent upgrades. This scalability is complemented by Cisco's commitment to backward compatibility, allowing businesses to integrate new systems with existing setups seamlessly.

In terms of performance, the VC-289 boasts impressive processing power. With advanced multi-core architecture, it is capable of handling multiple data streams simultaneously, making it ideal for environments that require consistent data flow, such as cloud computing and IoT applications. The device’s high throughput ensures that users experience minimal latency, facilitating quick data transfers even during peak usage times.

Security is another key characteristic of the VC-289. Cisco has integrated robust security protocols that protect against various cyber threats. Through features such as advanced encryption standards and intrusion prevention systems, organizations can ensure that sensitive data remains secure and is not compromised during transmission.

Another notable technology within the VC-289 is its support for software-defined networking (SDN) capabilities. This allows for more flexible network management, enabling IT teams to adapt the network according to evolving business needs. The ability to programmatically control the network also means that businesses can implement changes more rapidly, reducing downtime and improving overall productivity.

The VC-289 is designed with energy efficiency in mind, featuring power-saving modes that help reduce operational costs. This focus on sustainability not only benefits the environment but also appeals to organizations striving to meet corporate social responsibility objectives.

In conclusion, the Cisco Systems VC-289 stands as an exemplary solution for modern networking challenges. With its scalability, performance capabilities, enhanced security features, SDN support, and energy efficiency, it meets the demands of today's fast-paced and ever-evolving technological landscape. Organizations looking to invest in a robust networking solution would do well to consider the VC-289 as a cornerstone of their infrastructure.
