Tip To save the gateway configuration, save it to NVRAM. Refer to the “Saving Configuration Changes” section on page 57.

Note For comprehensive information about how to implement a Cisco AAA-based security environment, see the relevant documents at Cisco Product Documentation > Network Security > Cisco IOS Technology-Specific Security Features.

Configure Basic Dial Access

To commission a basic dial access service perform the following tasks:

Create two loopback interfaces.

Bring up the Fast Ethernet interface.

Add an IP route to the default gateway.

Step 1 Enter global configuration mode. You are in global configuration mode when your prompt changes to Gateway(config)#.

Gateway# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Gateway(config)#

Step 2 Assign the IP addresses as in the following example, and create an IP route to the default gateway:

Gateway(config)# interface loopback 0

Gateway(config-if)#

ip address 172.22.99.1 255.255.255.255

Gateway(config-if)#

exit

Gateway(config)# interface loopback 1

Gateway(config-if)#

ip address 172.22.90.1 255.255.255.0

Gateway(config-if)#

exit

Gateway(config)# interface FastEthernet 0/0

Gateway(config-if)#

ip address 172.28.186.55 255.255.255.240

Gateway(config-if)#

no shutdown

Gateway(config-if)#

exit

Gateway(config)# ip

route 0.0.0.0 0.0.0.0 172.28.186.49

In this example:

Interface loopback 0—Identifies with a unique and stable IP address. One unique IP address from a common block of addresses is assigned to each device in the IP network. This technique makes security-filtering easy for the Network Operations Center (NOC). One class C subnet used for device identification can support 254 distinct devices with unique loopback addresses.

Interface loopback 1—Hosts a pool of IP addresses for the remote nodes. In this way, one route, instead of 254 routes, is summarized and propagated to the backbone. Pick the IP address for loopback 1 from the range of addresses that you will assign to the local address pool.

Step 3 Return to privileged EXEC mode:

Gateway(config)# Ctrl-Z

Gateway#

Cisco AS5400, Cisco AS5350 specifications

Cisco Systems is a global leader in networking and telecommunications technology, and its AS5350 and AS5400 models are prominent offerings in their product line. These devices cater primarily to service providers and large enterprises looking for advanced VoIP, data, and multimedia capabilities.

The Cisco AS5350 is a versatile voice gateway that supports a wide range of protocols including VoIP and PSTN (Public Switched Telephone Network). Designed for scalability, it can handle numerous simultaneous calls, making it an ideal solution for businesses that require robust communication systems. Some of its main features include built-in support for various signaling protocols such as SIP (Session Initiation Protocol) and H.323, which allow seamless integration with existing networks. Additionally, the AS5350 is equipped with high-density digital signal processors (DSPs) that enable efficient call processing and transcoding, ensuring high-quality voice transmission.

On the other hand, the Cisco AS5400 takes this functionality a step further by offering enhanced capabilities suited for more demanding environments. It supports both voice and data services, allowing service providers to deliver a comprehensive solution that includes voice calls, multimedia applications, and broadband services. The AS5400 features a modular design, allowing users to adapt the device to specific needs by adding or removing modules as required. This modularity enhances flexibility and future-proofs the system against evolving technology demands.

Both the AS5350 and AS5400 incorporate advanced security features to protect sensitive communications and data. Features such as encryption, secure signaling, and network access controls are essential for enterprises looking to safeguard their operations in an increasingly vulnerable digital landscape. These gateways also support Quality of Service (QoS) protocols, ensuring that voice traffic is prioritized over other types of data, thereby maintaining call clarity even in times of high data demand.

In conclusion, the Cisco AS5350 and AS5400 are compelling solutions that showcase Cisco's commitment to delivering reliable and high-performance telecommunications devices. By offering state-of-the-art technology, robust features, and a modular approach to scalability, businesses and service providers can ensure they remain competitive in the ever-evolving telecommunications landscape. Whether it is for voice, data, or multimedia applications, these gateways deliver the performance and flexibility needed to meet current and future challenges.
