Oversubscribing the bandwidth limit recommendations of a router can result in decreased or degraded performance. For this reason, it is important to determine the amount of bandwidth used by the SPAs on the router and verify that the total bandwidth used by all SPAs does not exceed the recommended bandwidth limit of the router. It is also important not to exceed the bandwidth of the SIP. For information on SIP bandwidth, see the SIP Summary.
The processing on the Cisco CRS-1 SIP-800 is performed by two PLIM ASICs, each of which can process up to 20 Gbps of traffic. SPA subslots 0, 1, and 3 are associated with one PLIM ASIC, while SPA subslots 2, 4, and 5 are associated with the second PLIM ASIC. See the figure below for subslot locations.

Subslots controlled by one PLIM ASIC |

If you are using only Gigabit Ethernet SPAs on the Cisco CRS-1 SIP-800, then the SIP can be oversubscribed. The Cisco CRS-1 SIP-800 can pass a maximum of 40 Gbps of traffic, so if you have six 8-Port Gigabit Ethernet SPAs operating at almost full capacity, the SIP is oversubscribed.
If you are using any Packet Over Sonet (POS) SPAs in the Cisco CRS-1 SIP-800, regardless of the bandwidth of the SPA interfaces (OC-3c/STM-1, OC-12c/STM-4, OC-48c/STM-16, or OC-192c/STM-64), no oversubscription of either PLIM ASIC is allowed, nor can the total bandwidth of the SIP exceed 40 Gbps. For this reason, you can install a maximum of four OC-192c/STM-64 POS SPAs in the Cisco CRS-1 SIP-800. Two of them must be installed in subslots 0, 1, or 3; the other two must be installed in subslots 2, 4, or 5. The following arrangement of SPAs within the SIP indicates a valid configuration that optimizes the use of the available PLIM ASIC bandwidth:
Subslot 0: OC-192c/STM-64 POS SPA |
Subslot 1: OC-192c/STM-64 POS SPA |
Subslot 2: 8-Port Gigabit Ethernet SPA |
Subslot 3: Empty |
Subslot 4: 8-Port Gigabit Ethernet SPA |
Subslot 5: 4-Port OC-3c/STM-1 POS SPA |
In this example, because at least one OC-192c/STM-64 POS SPA is installed, the maximum bandwidth allowed on the first PLIM ASIC (associated with subslots 0, 1, and 3) is 20 Gbps, and the total capacity of the SIP is controlled to be 40 Gbps or less. The total bandwidth usage required in this example is 36 Gbps.
The ingress oversubscription of Cisco CRS-1 SIP-800 with ATM SPA is supported in the following conditions:
If you attempt to install a SPA that oversubscribes the SIP, the SPA does not power up, and you receive an error message similar to the following:
LC/0/2/CPU0:Jan 31 11:52:57.335 : jacket[159]: %JACKET-3-RULES_FATAL_ERROR : SPA subslot 4: FAILED: Not enough bandwidth for 1xOC192 POS/RPR HHSPA with XFP
For the Cisco CRS-3 Flexible PLIM, none of the SPAs supported as of 4.3.0 exceed 10G in capacity. Therefore, it is theoretically impossible to oversubscribe the two PLIM ASICs. However, there is an additional datapath bridge FPGA in the Cisco CRS-3 Flexible PLIM which can handle traffic only up to 61 million packets per second. If this limitation is breached, packet drops will be observed in the SPA path of the Cisco CRS-3 Flexible PLIM.
The table below provides information about the bandwidth for each port (per-port bandwidth) on a SPA and the cumulative bandwidth (total bandwidth) for all ports available on the SPA.

The physical layer interface for the 1-Port and 3-Port Clear Channel OC-3 ATM SPA is Optical Carrier-3 (OC-3), and the data link layer is designed to comply with ATM specifications. The 1-Port and 3-Port Clear Channel OC-3 ATM SPA provides up to one and three 155-Mbps OC-3 network interfaces, respectively, for all supported platforms.
Each SPA port accepts an SFP module with a duplex LC-type receptacle that allows connection to single-mode or multimode optical fiber.
The 1-Port and 3-Port Clear Channel OC-3 ATM SPA uses a small form-factor pluggable (SFP) optical transceiver module installed in each port for SONET and SDH single-mode and multimode optical fiber connection (see the figure below).
The SFP optical transceiver modules used with the 1-Port and 3-Port Clear Channel OC-3 ATM SPA provide the following optical fiber options:
Use a multimode optical fiber that has a core/cladding diameter of 62.5/125 microns.
Use a single-mode optical fiber that has a modal-field diameter of 8.7 ± 0.5 microns. (Nominal diameter is approximately 10/125 microns.)
For single-mode and multimode optical fiber connections, you can use either a duplex LC-type cable (see the figure below) or two simplex LC-type cables, one for transmit (TX) and one for receive (RX).
Use a single-mode (for intermediate-reach or long-reach configurations) or multimode optical fiber cable to connect your router to a network or to connect two OC-3-equipped routers back-to-back.
Long-range SFP optical transceiver modules (for long-reach configurations) cannot be connected back-to-back without using an attenuator between them.

Use a multimode optical fiber that has a core/cladding diameter of 62.5/125 microns.
Use a single-mode optical fiber that has a modal-field diameter of 8.7 ±0.5 microns. (Nominal diameter is approximately 10/125 microns.)
For single-mode and multimode optical fiber connections, you can use either a duplex LC-type cable (see the figure below) or two simplex LC-type cables, one for transmit (TX) and one for receive (RX).
The 4-Port and 8-Port OC-3c/STM-1 POS SPA is a single-width SPA that installs into one SIP subslot. The OC-3c/STM-1 POS SPA with small form-factor pluggable (SFP) optical transceiver modules provides SONET and SDH network connectivity with a per-port bandwidth of 155.52 Mbps. The 4-Port and 8-Port OC-3c/STM-1 POS SPA operates at quarter rate.
Note | The interconnect between a SIP and a SPA can operate at either 2.5Gbps or 10Gbps. If the maximum capacity of a SPA is greater than 2.5Gbps the interconnect operates at 10Gbps and the SPA is a "full-rate" SPA. If the maximum capacity of a SPA is 2.5Gbps or less the interconnect operates at 2.5Gbps and the SPA is a "quarter-rate" SPA.When SFP modules are replaced, the SPA interface retains any previously defined configurations. These configurations include settings for IP address, clock source, loopback, Cyclic Redundancy Check (CRC), and POS flags. |

The 4-Port and 8-Port OC-12c/STM-4 Multirate POS SPA is a single-width SPA that installs into one SIP subslot. The SPA with small form-factor pluggable (SFP) optical transceiver modules provides Optical Carrier Level (OC-n ) for SONET and Synchronous Transport Module (STM-n ) for SDH network connectivity. On this SPA, any given port can use either an OC-3 or OC-12 SFP module, so the per-port bandwidth can be either 155.52 Mbps or 622.08 Mbps, respectively, depending on the customer configuration.
Note | When SFP modules are replaced, the SPA interface retains any previously defined configurations. These configurations include settings for IP address, clock source, loopback, CRC, and POS flags. |

The 5-Port Gigabit Ethernet SPA has five electrical connectors that support SFP modules. Each port can send and receive traffic using cabling appropriate for the SFP module inserted.
The small form-factor pluggable (SFP) module is an input/output (I/O) device that plugs into the Gigabit Ethernet ports on the 5-Port Gigabit Ethernet SPA, linking the port with a fiber-optic network.
Note | The 5-Port Gigabit Ethernet SPA accepts only the SFP modules listed as supported in this document. An SFP module check is run every time an SFP module is inserted into the 5-Port Gigabit Ethernet SPA, and only SFP modules that pass this check can be used by the 5-Port Gigabit Ethernet SPA. SFP modules exist for technologies other than Gigabit Ethernet and for products other than the 5-Port Gigabit Ethernet SPA. However, the information in this document pertains only to SFP modules that plug into the 5-Port Gigabit Ethernet SPA ports. |
The SFP module has a receiver port (RX) and a transmitter port (TX) that compose one optical interface. The tables below provide SFP module information and specifications.

The 1000BASE-SX (short-wavelength) module operates on standard multimode fiber-optic link spans of up to 500 m on 50/125um multimode fiber (MMF) and 300 m on 62.5/125um MMF.
The 1000BASE-LX/LH (long-wavelength/long-haul) module interfaces fully comply with theIEEE 802.3z 1000BASE-LX standard. However, their higher optical quality allows them to reach 6.2 miles (10 km) over single-mode fiber (SMF) versus the 3.1 miles (5 km) specified in the standard.
The 1000BASE-ZX (extended wavelength) module operates on ordinary single-mode fiber-optic link spans of up to 49.7 miles (80 km). Link spans of up to 62.1 miles (100 km) are possible using premium single-mode fiber or dispersion-shifted single-mode fiber. (Premium single-mode fiber has a lower attenuation per unit length than ordinary single-mode fiber; dispersion-shifted single-mode fiber has both lower attenuation and less dispersion.)
The 1000BASE-ZX module must be coupled to single-mode fiber-optic cable, which is the type of cable typically used in long-haul telecommunications applications. The 1000BASE-ZX module does not operate correctly when coupled to multimode fiber, and it is not intended to be used in environments in which multimode fiber is frequently used (for example, building backbones or horizontal cabling).
The 1000BASE-ZX module is intended to be used as a Physical Medium Dependent (PMD) component for Gigabit Ethernet interfaces found on various switch and router products. It operates at a signaling rate of 1250 Mbaud, transmitting and receiving 8B/10B encoded data.
When shorter lengths of single-mode fiber are used, it may be necessary to insert an inline optical attenuator in the link to avoid overloading the receiver. Use the following guidelines:
The SFP-GE-T (1000BASE-T copper SFP module) provides full-duplex Gigabit Ethernet connectivity to high-end workstations and between wiring closets over an existing copper network infrastructure. The SFP-GE-T maximum cabling distance is 328 feet (100 m).
The table below provides cabling specifications for the SFP modules that can be installed on the 5-Port Gigabit Ethernet SPA. Note that all SFP ports have LC-type connectors.
The minimum cable distance for the SFP-GE-S is 6.5 feet (2 m), and the minimum link distance for the SFP-GE-Z is 6.2 miles (10 km) with an 8-dB attenuator installed at each end of the link. Without attenuators, the minimum link distance for the SFP-GE-Z is 24.9 miles (40 km).

Note | The 1000BASE-ZX SFP modules provide an optical power budget of 21.5 dB. You should measure your cable plant with an optical loss test set to verify that the optical loss of the cable plant (including connectors and splices) is less than or equal to 21.5 dB. The optical loss measurement must be performed with a 1550-nm light source. |

The interface connectors on the 8-Port Gigabit Ethernet SPA are eight individual fiber-optic receivers that support SFP modules. Each port can send and receive traffic using the optical fiber connections.
The small form-factor pluggable (SFP) module is an input/output (I/O) device that plugs into the Gigabit Ethernet ports on the 8-Port Gigabit Ethernet SPA, linking the port with a fiber-optic network.
Note | The 8-Port Gigabit Ethernet SPA accepts only the SFP modules listed as supported in this document. An SFP module check is run every time an SFP module is inserted into the 8-Port Gigabit Ethernet SPA, and only SFP modules that pass this check can be used by the 8-Port Gigabit Ethernet SPA. SFP modules exist for technologies other than Gigabit Ethernet and for products other than the 8-Port Gigabit Ethernet SPA. However, the information in this document pertains only to SFP modules that plug into the 8-Port Gigabit Ethernet SPA ports. |
The SFP module has a receiver port (RX) and a transmitter port (TX) that compose one optical interface. The tables below provide SFP module information and specifications.

The 1000BASE-SX (short-wavelength) module operates on standard multimode fiber-optic link spans of up to 500 m on 50/125um multimode fiber (MMF) and 300 m on 62.5/125um MMF.
The 1000BASE-LX/LH (long-wavelength/long-haul) module interfaces fully comply with the IEEE 802.3z 1000BASE-LX standard. However, their higher optical quality allows them to reach 6.2 miles (10 km) over single-mode fiber (SMF) versus the 3.1 miles (5 km) specified in the standard.
The 1000BASE-ZX (extended-wavelength) module operates on ordinary single-mode fiber-optic link spans of up to 49.7 miles (80 km). Link spans of up to 62.1 miles (100 km) are possible using premium single-mode fiber or dispersion-shifted single-mode fiber. (Premium single-mode fiber has a lower attenuation per unit length than ordinary single-mode fiber; dispersion-shifted single-mode fiber has both lower attenuation and less dispersion.)

The 1-Port 10-Gigabit Ethernet SPA supports the following types of optical transceiver modules:
Cisco Systems qualifies the optics that are approved for use with its SPAs. As of Cisco IOS XR Release 3.4.1, the above-listed small form-factor pluggable (XFPs) are the only optical transceiver modules qualified for use.
Use a single-mode optical fiber that has a modal-field diameter of 8.7 ±0.5 microns (nominal diameter is approximately 10/125 microns) to connect your router to a network.
The figure below shows the cable type for use with the XFP optical transceiver module on the 1-Port 10-Gigabit Ethernet SPA.
Note | The 40-pin connector on the 1-Port 10-Gigabit Ethernet SPA is used for resilient packet ring (RPR) connections. This feature is not supported inCisco IOS XR Release 3.4.1. |
The 10GLR, 10GER, and 10GZR XFP modules include an optical transmitter and receiver pair integrated with Clock and Data Recovery (CDR) integrated circuits. The XFP modules provide high-speed serial links at the rate of 10.3125 Gbps (10 Gigabit Ethernet) on single-mode fiber (SMF). The transmit side recovers and retimes the 10-Gbps serial data and passes it to a laser driver. The laser driver biases and modulates a 1310-nm, 850 nm or 155-nm laser, enabling data transmission over SMF through an LC connector. The receive side recovers and retimes the 10-Gbps optical data stream from a photo detector transimpedance amplifier and passes it to an output driver.
See the label on the XFP module for technology type and model. The figure below shows an XFP module and the table below shows the XFP module specifications.

The framer processes incoming and outgoing T3 (cbit, m13/m23, and unframe) and E3 (g751, g832, and unframe) frames. The framer operates at T3/E3 line rates (44.736 /34.368 Mbps) depending on the mode in which it is configured.
Packet data is transported with a user-configurable encapsulation (such as Point-to-Point Protocol [PPP] or High-Level Data Link Control [HDLC]), and is mapped to T3 and E3 frames. The encapsulations add transport overhead to the packet of data frames before transporting, and are stripped when a packet is transported to the far end.
The T3/E3 SPA interface is compliant with ANSI and Telco standards. The interface also provides support for Management Information Base (MIB) RFC 2496 and T1.231.
The interface connectors on the 2-Port and 4-Port Clear Channel T3/E3 SPA are 75-ohm coaxial Siemax types, with one connector and cable for transmit (TX) and one for receive (RX).
The following cables can be used with the 2-Port and 4-Port Clear Channel T3/E3 SPA. The cables have BNC connectors on one end and the Siemax connectors on the other. If similar SPAs are connected back-to-back, both ends of cable will be Siemax.
Note | The Cisco cable part numbers are 72-4124-01 (with male BNC end) and 72-4131-01 (with female BNC end). |
