C H A P T E R 4 Configuring the PA-POS-2OC3 To continue your port adapter installation you must configure the Packet-over-SONET (POS) interfaces. The following instructions apply to all supported platforms. Minor differences among the platforms—with Cisco IOS software commands—are noted. This chapter contains the following sections: • Using the EXEC Command Interpreter, page 4-1 • Configuring the Interfaces, page 4-2 • Customizing the Configuration, page 4-5 • Checking the Configuration, page 4-8 • Push/Pull Mode Description, page 4-30 • PA-POS-2OC3 Statistics Counters, page 4-30 • PA-POS-2OC3 Error Messages, page 4-31 • Making a Back-to-Back Connection, page 4-32 Using the EXEC Command Interpreter You modify the configuration of your router through the software command interpreter called the EXEC (also called enable mode). You must enter the privileged level of the EXEC command interpreter with the enable command before you can use the configure command to configure a new interface or change the existing configuration of an interface. The system prompts you for a password if one has been set. The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, use the following procedure to enter the privileged level: Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a privileged-level password. Router> enable Password: Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed. When you enter the correct password, the system displays the privileged-level system prompt (#). Router# PA-POS-2OC3 Two-Port Packet-over-SONET Port Adapter Installation and Configuration OL-3028-06 4-1 Chapter 4 Configuring the PA-POS-2OC3 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-2OC3 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-2OC3 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-2OC3 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 a PA-POS-2OC3, refer to the appropriate configuration publications listed in the “Related Documentation” section on page iv. 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 4-1 for 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-2OC3 is shut down. To enable the interfaces, you must enter the no shutdown command in configuration mode. (See “Performing a Basic Interface Configuration” section on page 4-3.) 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. Table 4-1 PA-POS-2OC3 Configuration Default Values Parameter1 Configuration Commands Default Value MTU mtu bytes (no mtu bytes) 4470 bytes Framing pos framing sdh (no pos framing sdh) SONET framing Loopback internal loop internal (no loop internal) No internal loopback Loopback line loop line (no loop line) No line loopback Transmit clocking source clock source internal clock source line Loop timing Cyclic redundancy checks crc 16 crc 32 crc 16 SONET payload scrambling pos scramble-atm (no pos scramble-atm) No scrambling 1. These default parameters apply to the PA-POS-2OC3 in all supported platforms. PA-POS-2OC3 Two-Port Packet-over-SONET Port Adapter Installation and Configuration 4-2 OL-3028-06 Chapter 4 Configuring the PA-POS-2OC3 Configuring the Interfaces Performing a Basic Interface Configuration Following are instructions for performing a basic configuration, which include enabling an interface (with the no shutdown command) and specifying IP routing. You might also need to enter other configuration commands, depending on the requirements for your system configuration and the protocols you plan to route on the interface. For complete descriptions of configuration commands and the configuration options available for the interfaces of your port adapter, refer to the appropriate software documentation. In the following procedure, press the Return key after each step unless otherwise noted. At any time, you can exit the privileged level and return to the user level by entering disable at the prompt as follows: Router# disable Router> Note The Cisco 7200 VXR Port Adapter Jacket Card requires no configuration. Configure a port adapter in it as you would any other port adapter. 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 subcommand, followed by the interface address of the interface you plan to configure. Table 4-2 gives examples of the interface pos subcommand for the supported platforms. Table 4-2 Examples of the interface pos Subcommand for the Supported Platforms Platform Cisco 7200 VXR routers Cisco 7201 router Cisco 7301 router 1 Command Example interface pos, followed by slot/port (port-adapter-slot-number/ interface-port-number) This example is for interface 0 of a PA-POS-2OC3 in port adapter slot 6: interface pos, followed by slot/port (port-adapter-slot-number/ interface-port-number) The example is for interface 1 of a PA-POS-2OC3 in port adapter slot 1: interface pos, followed by slot/port (port-adapter-slot-number/ interface-port-number) The example is for interface 1 of a PA-POS-2OC3 in port adapter slot 1: Cisco 7304 PCI port adapter carrier card interface pos, followed by in a Cisco 7304 router slot/port (module-slot-number/ interface-port-number) Router(config)# interface pos 6/0 Router(config-if)# Router(config)# interface pos 1/1 Router(config-if)# Router(config)# interface pos 1/1 Router(config-if)# The example is for 3 interface 0 of a PA-POS-2OC3 in a Cisco 7304 PCI Port Adapter Carrier Card in module slot 3 of a Cisco 7304 router. Router(config)# interface pos 3/0 Router(config-if)# PA-POS-2OC3 Two-Port Packet-over-SONET Port Adapter Installation and Configuration OL-3028-06 4-3 Chapter 4 Configuring the PA-POS-2OC3 Configuring the Interfaces Table 4-2 Examples of the interface pos Subcommand for the Supported Platforms (continued) Platform Command Example Cisco 7401ASR router interface pos, followed by slot/port (port-adapter-slot-number/ interface-port-number) The example is for interface 1 of a PA-POS-2OC3 in port adapter slot 1: interface 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. VIPs in the Cisco 7500 series routers (7505, 7507, 7513) Cisco 7600 series routers (7603, 7606, 7609, 7613) with FlexWAN or Enhanced FlexWAN Router(config)# interface pos 1/1 Router(config-if)# Router(config)# interface pos 1/1/0 Router(config-if)# shutdown Ctrl-Z Router# interface pos followed by slot/port Module slot number—22 through 6 or 9 adapter/port (depending on the number of slots in the switch) module-slot-number/ port-adapter-bay-number/ interface-port-number Router(config)# interface pos 1/1/0 Router(config-if)# shutdown Ctrl-Z Router# 1. For the Cisco 7206VXR router shelves, the interface specified in the above example would include a shelf number. For example, the command interface pos 5/3/0 specifies the OC-3 interface of the PA-POS-2OC3 in port adapter slot 3 of router shelf 5. 2. Slot 1 is reserved for the supervisor engine. If a redundant supervisor engine is used, it must go in slot 2; otherwise, slot 2 can be used for other modules. 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 Cisco PA-POS-2OC3 port adapter 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. PA-POS-2OC3 Two-Port Packet-over-SONET Port Adapter Installation and Configuration 4-4 OL-3028-06 Chapter 4 Configuring the PA-POS-2OC3 Customizing the Configuration 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-2OC3 configuration: Note • Setting the MTU Size, page 4-5 • Configuring Framing, page 4-6 • Setting the Source of the Transmit Clock, page 4-6 • Configuring Cyclic Redundancy Checks, page 4-6 • Configuring SONET Payload Scrambling, page 4-7 • Configuring APS, page 4-7 The interface subcommands that follow function the same regardless of the platform in which your PA-POS-2OC3 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 4-2 on page 4-3. Setting the MTU Size Note 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) interfaces for autonomous switching. The default MTU size is 4470 bytes. Step 1 To set the MTU size, enter the mtu bytes command, where bytes is a value in the range of 64 to 9216. Router(config)# interface pos 3/0 Router(config-if)# mtu 3000 Step 2 To restore the default of 4470 bytes, enter the no mtu command. PA-POS-2OC3 Two-Port Packet-over-SONET Port Adapter Installation and Configuration OL-3028-06 4-5 Chapter 4 Configuring the PA-POS-2OC3 Customizing the Configuration Configuring Framing The default framing value is SONET STS-3c. Step 1 To configure for SDH STM-1, enter the pos framing sdh command: Router(config)# interface pos 3/0 Router(config-if)# pos framing sdh Step 2 To change back to SONET STS-3c, enter the no pos framing sdh command. Setting the Source of the Transmit Clock The clocking default value specifies that the PA-POS-2OC3 use the recovered receive (RX) clock to provide transmit (TX) clocking (called loop timing). Note Step 1 If line loopback is selected, the PA-POS-2OC3 is forced into loop timing mode until the loopback is disengaged. To specify that the Cisco PA-POS-2OC3 port adapter generate the transmit clock internally, enter the clock source internal command: Router(config)# interface pos 3/0 Router(config-if)# clock source internal Step 2 To restore loop timing, enter the no clock source internal command or the clock source line command. Configuring Cyclic Redundancy Checks The cyclic redundancy check (CRC) default value is a 16-bit CRC (CRC-CITT). The CRC is an error-checking technique that uses a calculated numeric value to detect errors in transmitted data. The PA-POS-2OC3 also supports a 32-bit CRC. The sender of a data frame calculates the frame check sequence (FCS). The sender appends the FCS value to outgoing messages. The receiver recalculates the FCS and compares it to the FCS from the sender. If a difference exists, the receiver assumes that a transmission error occurred and sends a request to the sender to resend the frame. Step 1 To configure an interface for a 32-bit CRC, enter the crc 32 command: Router(config)# interface pos 3/0 Router(config-if)# crc 32 Step 2 To disable the 32-bit CRC and return the interface to the default 16-bit CRC, enter the no crc 32 command. PA-POS-2OC3 Two-Port Packet-over-SONET Port Adapter Installation and Configuration 4-6 OL-3028-06 Chapter 4 Configuring the PA-POS-2OC3 Customizing the Configuration Configuring SONET Payload Scrambling The default value for SONET payload scrambling is disabled. SONET payload scrambling applies a self-synchronous scrambler (x^43+1) to the Synchronous Payload Envelope (SPE) of the OC-3 interface to ensure sufficient bit-transition density. Note Both ends of the connection must use the same scrambling algorithm. You enable SONET payload scrambling using the pos scramble-atm command. (This command has no keywords or arguments.) Step 1 To enable SONET payload scrambling, use the following command sequence: Router(config)# interface pos 3/0 Router(config-if)# pos scramble-atm Router(config-if)# no shutdown Router(config-if)# end Step 2 To verify that SONET payload scrambling is enabled on an interface, enter the show startup-config command. If scrambling is enabled, the following line is displayed in the configuration: pos scramble-atm Step 3 To disable SONET payload scrambling, use the no pos scramble-atm command. Configuring APS The automatic protection switching (APS) feature allows switchover of packet-over-SONET (POS) circuits in the event of circuit failure and is often required when connecting SONET equipment to telco equipment. APS refers to the mechanism of using a protect POS interface in the SONET network as the backup for working POS interface. When the working interface fails, the protect interface quickly assumes its traffic load. The following example shows the configuration of 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. If the working interface on router A becomes unavailable, the connection will automatically switch over to the protect interface on router B.

The aps group command is used even when a single protect group is configured. To verify the configuration or to determine if a switch over has occurred, use the show aps command.

This section provides a brief description of this command. Refer to the publications listed in the “Related Documentation” section on page iv for detailed command descriptions and examples. The ping command sends echo request packets out to a remote device at an IP address that you specify. After sending an echo request, the system waits a specified time for the remote device to reply. Each echo reply is displayed as an exclamation point (!) on the console terminal; each request that is not returned before the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the messages (timed out) or (failed) indicate a bad connection. Following is an example of a successful ping command to a remote server with the address 10.0.0.10: Router# ping 10.0.0.10Type escape sequence to abort. Sending 5, 100-byte ICMP Echoes to 10.0.0.10, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms Router# 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. The loopback command places an interface in internal loopback (also called local loopback) or line loopback mode, which enables test packets that are generated from the ping command to loop through a remote device or a cable. If the packets complete the loop, the connection is good. If not, you can isolate a fault to the remote device or the cable in the path of the loopback test. Note Engaging line loopback automatically switches the interface to loop timing. The interface switches back to the user-specified timing source once the loopback is disengaged. Configuring an Interface for Internal Loopback The default loopback setting is for no loopback. With internal (or local) loopback, packets from the router are looped back in the framer. Outgoing data gets looped back to the receiver without actually being transmitted. Internal loopback is useful for checking that the PA-POS-2OC3 is working. Step 1 To configure an interface for internal loopback, enter the loop internal command: Router(config)# interface pos 3/0 Router(config-if)# loop internal Step 2 To disable internal loopback, enter the no loop internal command. PA-POS-2OC3 Two-Port Packet-over-SONET Port Adapter Installation and Configuration OL-3028-06 4-29 Chapter 4 Configuring the PA-POS-2OC3 Push/Pull Mode Description Configuring an Interface for Line Loopback Note Engaging line loopback automatically switches the interface to loop timing. It switches back to the user-specified timing source when the loopback is disengaged. The default loopback setting is for no loopback. With line loopback, the receive (RX) fiber is logically connected to the transmit (TX) optical fiber cable so that packets from the remote router are looped back to it. Incoming data gets looped around and retransmitted to the remote end omitting the received part which is of no significance. 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. For more information about interface subcommands and the configuration options available for the individual platforms, refer to the publications listed in the “Related Documentation” section on page iv. Push/Pull Mode Description The PA-POS-2OC3 and PA-POS-1OC3 port adapters support a different algorithm (from that of most port adapters) for handling data. On the transmit side, it can either pull packets from the CPU (Pull mode) or push packets from the CPU to the port adapter (Push mode). The PA-POS-2OC3 and PA-POS-1OC3 port adapters were developed with a software architecture that deviates from the design of previously developed port adapters. A majority of the port adapters allow data to be pulled from the CPU to their interfaces. By default, the TX DMA mode is Pull for NPE-G1 and Push for NPE-G2. You cannot change the default TX DMA modes for NPE-G1 and NPE-G2 using the dma model pull enable command. For NPE-G1, the TX DMA mode is always Pull and for NPE-G2, the TX DMA mode is always Push. This functioanlity is implemented startingwith the following Cisco IOS Releases: 12.4(24)T01, 12.4(22)T02, 12.4(20)T03, 12.2(33)SRD02, 12.2(33)SRC04, 12.2(33)SB07, and 12.2(31)SB16. If you run the dma model pull enable command on NPE-G1, the running configuration shows that the Pull mode is enabled otherwise the information about Pull mode is not displayed in the running configuration. Running the dma model pull enable command on NPE-G2 results in an error message. Caution Only customers who have been advised by Cisco to use this CLI should do so. If you have not been advised by Cisco to use the dma model pull enable command, do not do so. PA-POS-2OC3 Statistics Counters The PA-POS-2OC3 maintains counts of certain errors. Each error counter is 16 bits. Errors include the following: PA-POS-2OC3 Two-Port Packet-over-SONET Port Adapter Installation and Configuration 4-30 OL-3028-06 Chapter 4 Configuring the PA-POS-2OC3 PA-POS-2OC3 Error Messages • CRC errors—Packet corrupted in reception • Giants received—Packet length too large (greater than 16 KB) • Runts—Packet length too small (less than or equal to 4 bytes) • Ignores—No receive buffers available; receive buffers full PA-POS-2OC3 Error Messages The only error message you should see is of the following type and format: %POS-0-MSG:%DEBUGGER-0-STACK_DATA8: 00E0 80032CD4 00000000 00000000 Note FFFFFFFF 80057F50 00000000 00000000 FFFFFFFF Contact the Cisco Technical Assistance Center (TAC) for assistance with this error message. PA-POS-2OC3 Two-Port Packet-over-SONET Port Adapter Installation and Configuration OL-3028-06 4-31 Chapter 4 Configuring the PA-POS-2OC3 Making a Back-to-Back Connection Making a Back-to-Back Connection This section provides an example of two sample configuration files from a Cisco 7200 VXR router and a Cisco 7401ASR router connected back-to-back through their OC-3 interfaces. Step 1 To connect two PA-POS-2OC3-equipped routers back to back, attach the appropriate cable between the OC-3 interface port on each PA-POS-2OC3. By default, the PA-POS-2OC3 uses loop timing mode. Step 2 To specify that the Cisco PA-POS-2OC3 port adapter generates the transmit clock internally, add the clock source internal command to your configuration (see the first router example above: clock source internal). Note For back-to-back operation, at least one of the connected OC-3 interfaces must be configured to supply its internal clock to the line.
