Chapter 4 Configuring the PA-POS-1OC3

Customizing the Configuration

Step 3 Assign an IP address and subnet mask to the interface (if IP routing is enabled on the system) by using the ip address configuration subcommand, as in the following example:

Router(config-if)#ip address 10.0.0.10 255.255.255.255

Step 4 Change the shutdown state to up and enable the interface as follows:

Router(config-if)# no shutdown

The no shutdown command passes an enable command to the interface and causes the PA-POS-1OC3 to configure itself based on the previous configuration commands sent.

Step 5 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.

Step 6 After including all of the configuration commands to complete your configuration, press Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit configuration mode and return to the EXEC command interpreter prompt.

Step 7 Write the new configuration to NVRAM as follows:

Router# copy running-config startup-config

[OK]

Router#

This completes the procedure for creating a basic configuration. To check the interface configuration with show commands, proceed to the “Checking the Configuration” section on page 4-12.

Customizing the Configuration

You can customize the default values of all configuration parameters to match your network environment. Use the interface subcommands in the following sections if you need to customize the PA-POS-1OC3 configuration:

•Setting the MTU Size, page 4-9

•Configuring Framing, page 4-9

•Setting the Source of the Transmit Clock, page 4-9

•Configuring Cyclic Redundancy Checks, page 4-10

•Configuring SONET Payload Scrambling, page 4-10

•Configuring APS, page 4-11

The interface subcommands that follow function the same regardless of the platform in which your PA-POS-1OC3 is installed; however, all these commands require that you first enter the interface pos command to select the interface that you want to configure. In all the configuration examples that follow, the interface address argument for the interface pos command is for a Cisco 7200 VXR router: 3/0 (port adapter slot 3, interface 0).

For the appropriate interface pos command syntax to use for your particular platform, see Table 4-4 on page 4-7.

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.
