Cisco Systems PA-POS-2OC3, PA-POS-1OC3 manual Customizing the Configuration

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.
