Chapter 4 Configuring the PA-POS-1OC3

Configuring the Interfaces

To configure the new interfaces, proceed to the “Configuring the Interfaces” section on page 4-2.

Configuring the Interfaces

After you verify that the new PA-POS-1OC3 is installed correctly (the ENABLED LED goes on), use the privileged-level configure command to configure the new interfaces. Have the following information available:

•IP addresses, if you plan to configure the interface for IP routing

•MTU size

•Framing mode

•Transmit clock source

•Loopback modes (if testing is required)

If you installed a new PA-POS-1OC3 or if you want to change the configuration of an existing interface, you must enter configuration mode to configure the new interfaces. If you replaced a PA-POS-1OC3 that was previously configured, the system recognizes the new interfaces and brings each of them up in their existing configurations.

For a summary of the configuration options available and instructions for configuring the interfaces on

aPA-POS-1OC3, refer to the appropriate configuration publications listed in the “Related Documentation” section on page viii.

You execute configuration commands from the privileged level of the EXEC command interpreter, which usually requires password access. (See the “Using the EXEC Command Interpreter” section on page 4-1for an explanation of the privileged level of the EXEC.) Contact your system administrator, if necessary, to obtain password access.

On power-up, the OC-3 interface on a new PA-POS-1OC3 is shut down. To enable the interfaces, you must enter the no shutdown command in configuration mode. (See “Performing a Basic Configuration” section on page 4-6.) When the OC-3 interface is enabled (taken out of shutdown) with no additional arguments, the default interface configuration file parameters look like those in Table 4-1.

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.
