C H A P T E R 4 Configuring the PA-POS-1OC3 The following instructions apply to all supported platforms. Minor differences among the platforms—with Cisco IOS software commands—are noted.
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.
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.
Chapter 4 Configuring the PA-POS-1OC3 Configuring the Interfaces Table 4-2 Syntax of the shutdown Command for the Supported Platforms (continued) Platform Command Cisco 7401ASR router interface, followed by the type (pos) and The example is for interface 0 on a port adapter in slot 1.
Chapter 4 Configuring the PA-POS-1OC3 Configuring the Interfaces Table 4-3 provides examples of the show interfaces pos command for the supported platforms. Table 4-3 Examples of the show interfaces pos Command for the Supported Platforms PLatform Cisco 7200 VXR routers 1 Command Example show interfaces pos, followed by slot/port (port-adapter-slot-number/ interface-port-number) The example is for interface 0 on a port adapter in slot 6.
Chapter 4 Configuring the PA-POS-1OC3 Configuring the Interfaces Table 4-3 Examples of the show interfaces pos Command for the Supported Platforms (continued) PLatform Command Example VIP in the Cisco 7500 series routers (7505, 7507, 7513) show interfaces pos followed by slot/port-adapter/port (interface-processor-slot-number/ port-adapter-slot-number/ interface-port-number) The example is for interface 0 in port adapter slot 1 of a VIP installed in interface processor slot 1.
Chapter 4 Configuring the PA-POS-1OC3 Configuring the Interfaces Step 1 Enter configuration mode and specify that the console terminal will be the source of the configuration subcommands as follows: Router# configure terminal Enter configuration commands, one per line. Router(config)# Step 2 End with CNTL/Z. Specify the new interface to configure by entering the interface pos command, followed by the interface address of the interface you plan to configure.
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.
Chapter 4 Configuring the PA-POS-1OC3 Customizing the Configuration Setting the MTU Size Note Step 1 The default MTU size is 4470 bytes. The default value, 4470 bytes, exactly matches the maximum transmission unit (MTU) of the fiber distributed data interface (FDDI) and high-speed serial interface (HSSI) for autonomous switching. To set the MTU size, enter the mtu bytes command, where bytes is a value in the range of 64 to 117994.
Chapter 4 Configuring the PA-POS-1OC3 Customizing the Configuration Step 2 To restore loop timing, enter the no clock source internal command or the clock source line command. Router(config)# interface pos 3/0 Router(config-if)# no clock source internal Configuring Cyclic Redundancy Checks The cyclic redundancy check (CRC) default is for a 16-bit CRC. The CRC is an error-checking technique that uses a calculated numeric value to detect errors in transmitted data.
Chapter 4 Configuring the PA-POS-1OC3 Customizing the Configuration Step 3 To disable SONET payload scrambling, use the no pos scramble-atm command. Router(config)# interface pos 3/0 Router(config-if)# no pos scramble-atm Configuring APS The following example shows the configuration of automatic protection switching (APS) on router A and router B. (See Figure 4-1.) In this example, router A is configured with the working interface, and router B is configured with the protect interface.

Chapter 4 Configuring the PA-POS-1OC3 Checking the Configuration Using the show interfaces Command Display status information (including the physical slot and interface address) for the interfaces you specifyusing the show interfaces command. For complete descriptions of interface subcommands and the configuration options available, refer to the publications listed in the “Related Documentation” section on page viii.

In this example, the pos interfaces is on a port adapter in port adapter slot 1 of a VIP in interface processor slot 1.
Chapter 4 Configuring the PA-POS-1OC3 Checking the Configuration If the connection fails, verify that you have the correct IP address for the destination and that the device is active (powered on), and repeat the ping command. Using loopback Commands The loopback test allows you to troubleshoot, detect, and isolate equipment malfunctions by testing the connection between the OC-3 interface and a remote device.
Chapter 4 Configuring the PA-POS-1OC3 Push Mode Description Step 1 To configure an interface for line loopback, enter the loop line command: Router(config)# interface pos 3/0 Router(config-if)# loop line Step 2 To disable line loopback, enter the no loop line command.
Chapter 4 Configuring the PA-POS-1OC3 PA-POS-1OC3 Statistics Counters Caution On the execution of either command, all thePA-POS-1OC3 and PA-POS-2OC3 port adapters installed in the router will be soft OIRed. PA-POS-1OC3 Statistics Counters The PA-POS-1OC3 maintains counts of certain errors. Each error counter is 16 bits long.
Chapter 4 Configuring the PA-POS-1OC3 Making a Back-to-Back Connection Step 1 To connect two PA-POS-1OC3-equipped routers back to back, attach the appropriate cable between the OC-3 interface port on each PA-POS-1OC3. By default, the PA-POS-1OC3 uses loop timing mode. Step 2 To specify that the PA-POS-1OC3 generates the transmit clock internally, add the clock source internal command to your configuration (see the first router example above: clock source internal).
