Chapter 4 Configuring the PA-POS-1OC3

Configuring the Interfaces

Shutting Down an Interface

Before you remove an interface that you will not replace, or replace port adapters, use the shutdown command to shut down (disable) the interfaces to prevent anomalies when you reinstall the new or reconfigured interface processor. When you shut down an interface, it is designated administratively down in the show command displays.

Follow these steps to shut down an interface:

Step 1 Enter the privileged level of the EXEC command interpreter (also called enable mode). (See the "Using the EXEC Command Interpreter" section for instructions.)

Step 2 At the privileged-level prompt, enter configuration mode and specify that the console terminal is the source of the configuration subcommands, as follows:

Router# configure terminal

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

Router(config)#

Step 3 Shut down interfaces by entering the interface pos subcommand (followed by the interface address of the interface), and then enter the shutdown command.

When you have finished, press Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit the configuration mode and return to the EXEC command interpreter.

Table 4-2shows the shutdown command syntax for the supported platforms.

PA-POS-1OC3, PA-POS-2OC3 specifications

Cisco Systems has long been at the forefront of networking technology, providing solutions that empower organizations to enhance their connectivity and communication capabilities. Among its impressive lineup, the PA-POS-2OC3 and PA-POS-1OC3 modules stand out as significant components designed to optimize performance in service provider and enterprise environments.

The PA-POS-2OC3 and PA-POS-1OC3 modules are designed for use with the Cisco 7600 Series routers and are tailored for Packet Over SONET (POS) transport. Supporting the OC-3 speed of 155.52 Mbps, these modules provide reliable high-speed connectivity, enabling organizations to efficiently manage data traffic and ensure rapid data transfer across their networks. The PA-POS-2OC3 offers dual OC-3 capabilities, allowing for higher aggregate bandwidth and redundancy options, making it common in demanding network environments.

One of the main features of the PA-POS-2OC3 and PA-POS-1OC3 is their enhanced support for advanced networking protocols, including MPLS (Multiprotocol Label Switching). MPLS facilitates efficient data routing and improves bandwidth utilization by enabling multiple types of traffic to be consolidated over a single network. This is crucial for organizations looking to deploy services like VoIP, video conferencing, and other bandwidth-intensive applications.

The modules also offer robust error correction and monitoring capabilities, which are essential for maintaining service quality in mission-critical applications. Administrators can monitor performance and diagnose issues in real-time, enabling swift responses to potential concerns that could disrupt service.

Moreover, the PA-POS-2OC3 and PA-POS-1OC3 are designed with features that support enterprise-grade security and scalability. This is particularly beneficial for organizations expecting growth or requiring enhanced protection for sensitive data as it traverses the network.

In summary, Cisco's PA-POS-2OC3 and PA-POS-1OC3 modules represent essential building blocks for high-speed networking solutions. Their support for OC-3 connectivity, advanced routing protocols, and robust monitoring capabilities make them ideal for both service providers and enterprises. Through increased scalability, improved bandwidth management, and enhanced security, these modules allow organizations to adapt to the ever-evolving landscape of data communications effectively. With Cisco at the helm, businesses can trust in a networking solution that not only meets current demands but is also primed for future growth.
