  • Page 19: Interface Processor Replacement Procedures

    Interface Processor Replacement Procedures Typically, your interface processors arrive preinstalled in your Cisco 7000 series and Cisco 7500 series routers (with the exception of the Cisco 7513); however, occasionally you might have to remove and replace interface processors for maintenance.
  • Page 20 Interface Processor Replacement Procedures If you install or remove other interface processors in a Cisco 7000 series or Cisco 7500 series Note router with a CT3IP installed, you might have to reboot the system after the removal and replacement of that interface processor. (In general, and to prevent system problems, we recommend you follow the procedures described in this section and the guidelines described in the preceding section “Guidelines for Interface Processor Removal and Installation.”)
  • Page 21 Cisco 7507 and Cisco 7513, we recommend that you install interface processors starting with the slots closest to the RSPs and work out concentrically from there. This will help prevent electromagnetic interference (EMI).
  • Page 22 Interface Processor Replacement Procedures Interface processors and interface processor fillers are secured with two captive Step 3 installation screws. (See Figure 8a.) Use a flat-blade screwdriver to loosen the captive installation screws and remove the interface processor filler (or the existing interface processor) from the slot.
  • Page 23: Atm Interface Cables

    ATM Interface Cables Place the back of the interface processor in the slot and align the notch on the bottom of Step 5 the carrier with the groove in the slot. (See Figure 8a.) While keeping the interface processor parallel to the backplane, carefully slide the Step 6 interface processor into the slot until the back of the faceplate makes contact with the ejector levers, then stop.
  • Page 24 ATM Interface Cables Following are descriptions of the network interface cables used with the AIP. • For TAXI 4B/5B traffic over multimode fiber, use the multimode MIC interface cable to connect the AIP with the external ATM switch.

  • Page 28 ATM Interface Cables Attaching Network Interface Cables to the AIP All AIP interfaces are full duplex. You must use the appropriate ATM interface cable to connect the AIP to an external ATM network. The AIP provides an interface to an ATM switching fabric for transmitting and receiving data at up to 155 megabits per second (Mbps) bidirectionally.
  • Page 29 ATM Interface Cables Use the following procedure to install a CAB-ATM-DS3/E3 cable and EMI filter clip: Attach the CAB-ATM-DS3/E3 cable to the transmit (XMTR) and receive (RCVR) ports Step 1 on the E3 PLIM, as shown in Figure 21A. One portion of the cable has a white insulator on both ends to ensure that the receive-to-transmit and transmit-to-receive relationship is maintained between the E3 PLIM and your ATM switch.

  • Page 31 Using LEDs to Check AIP Status AIP LEDs function as follows: • Enabled—When on, this LED indicates that the AIP is enabled for operation; however, the interface ports might not be functional or enabled. • RX cells —When on, indicates that the AIP has received an ATM cell. This LED will flicker in normal operation, indicating traffic.
  • Page 32: Configuring The Aip

    Configuring the AIP Use the show interfaces or show controllers cbus command to verify the status of the Step 5 ATM interface. (If the ATM interface is not configured, you must use the procedures in the section “Configuring the AIP” to configure the interface.) If an error message displays on the console terminal, refer to the appropriate reference publication for error message definitions.
  • Page 33 IP address, MTU size, AAL mode, and desired rate queues. Interface Port Numbering for the ATM Interface The Cisco 7000 series and Cisco 7500 series routers identify an interface address by its interface processor slot number and port number in the format slot/port. Because each AIP contains a single ATM interface, the port number is always 0.
  • Page 34 Configuring the AIP At the prompt, specify the new ATM interface to configure by entering the interface Step 2 command, followed by the type (atm) and slot/port (interface processor slot number/port number). The example that follows is for an AIP in interface processor slot 1: Router(config)# interface atm 1/0 If IP routing is enabled on the system, you can assign an IP address and subnet mask to...
  • Page 35 Configuring the AIP Virtual circuits get the entire bandwidth of the associated rate queue. If over subscription occurs, the other rate queues in bank A will miss the service opportunities. In the worst case, a 10-Mbps rate queue will take 100 Mbps if there are 10 VCs attached to it and all of them have packets to send at the same time.
  • Page 36 Configuring the AIP Setting the MTU Size To set the maximum transmission unit (MTU) size, use the following command: Router(config-if)# mtu bytes where bytes is in the range of 64 through 9188 bytes; the default is 4470 bytes. (4470 bytes exactly matches FDDI and HSSI interfaces for autonomous switching.) The no form of the command restores the default: Router(config-if)# no mtu...
  • Page 37 AIP. These PVCs are writable into the nonvolatile RAM (NVRAM) as part of the configuration and are used when the Cisco IOS image is reloaded. Some ATM switches have point-to-multipoint PVCs that do the equivalent of broadcasting. If a point-to-multipoint PVC exists, then that PVC can be used as the sole broadcast PVC for all multicast requests.
  • Page 38 Configuring the AIP To create a PVC on the AIP interface, you use the atm pvc command as follows: Router(config-if)# atm pvc vcd vpi vci aal-encap protocol-type-for-mux [ peak-rate ] [ average-rate ] [ cell-quota ] where: • vcd is a per-AIP unique index value describing this VC in the range of 1 to MAXVC. •...
  • Page 39 AAL5 processing. Mapping a Protocol Address to a PVC The Cisco IOS software supports a mapping scheme that identifies the ATM address of remote hosts/routers. This address can be specified either as a virtual circuit descriptor (VCD) for a PVC or a network service access point (NSAP) address for SVC operation.
  • Page 40 Configuring the AIP AIP Statistics The AIP will maintain a count of certain errors. In addition to keeping a count of these errors, the AIP will also take a snapshot of the last VCI/VPI that caused an error. Each AIP error counter is 16 bits.
