Features of the Cisco ASR 1000 Series Embedded Services Processors


Cisco ASR 1000 Series Routers Embedded Services Processors


The Cisco ASR 1000 Series embedded services processors are based on the Cisco QuantumFlow Processor (QFP) for next-generation forwarding and queuing. The Cisco ASR1000-ESP5, Cisco ASR1000-ESP10, Cisco ASR1000-ESP10-N, Cisco ASR1000-ESP20, Cisco ASR1000-ESP40, Cisco ASR1000-ESP100, and Cisco ASR 1000-ESP200 provide centralized forwarding-engine options for the Cisco ASR 1000 Series Aggregation Services Routers.

Additionally, the Cisco ASR 1002 Fixed Router includes a nonmodular, fixed embedded services processor with a throughput of 2.5 Gbps and the Cisco ASR 1001 Router has a nonmodular, fixed embedded services processor with a throughput of 2.5 Gbps, which is upgradable with a software activated performance upgrade license to 5 Gbps.

The Cisco  ASR 1000 Series embedded service processors:

Provide the centralized embedded forwarding services responsible for the bulk of the data plane processing tasks. All network traffic through the Cisco ASR 1000 Series system flows through the Cisco ASR 1000 Series Embedded Services Processors.

Are responsible for the data-plane processing tasks and all network traffic flows through them.

Support Forwarding Engine Control Processor which provide hardware abstraction layer between the QFP-based forwarding engine and other system components, allowing datapath and management functions to be independent.

Support Cisco QuantumFlow Processor (QFP) forwarding engines.

Support QFP provisioned with two TCAM4 devices for ACL lookup and other software features.

Perform all baseline packet routing operations, including MAC classification, Layer 2 and Layer 3 forwarding, quality-of-service (QoS) classification, policing and shaping, security access control lists (ACLs), VPNs, load balancing, NetFlow.

Are responsible for features such as firewalls, intrusion prevention, Network Based Application Recognition (NBAR), Network Address Translation (NAT), and flexible pattern matching.

Incorporates a security encryption coprocessor to assist encryption processing common to all embedded services processors. The security processor operates in coprocessor mode and only processes packets sent to it by the Cisco QFP.

Provide hardware abstraction layer between the packet processing-based forwarding engine and other system components.

The Cisco ASR1000-ESP5, Cisco ASR1000-ESP10, Cisco ASR1000-ESP10-N, Cisco ASR1000-ESP20, Cisco ASR1000-ESP40, Cisco ASR1000-ESP100, and Cisco ASR1000-ESP200 provide centralized forwarding-engine options for the Cisco ASR 1000 Series Aggregation Services Routers. The Cisco ASR 1002-F Router includes a nonmodular, integrated embedded services processor with a forwarding bandwidth (throughput) of 2.5 Gbps. The integrated embedded services processor of the Cisco ASR 1002-X Router can provide a forwarding bandwidth of 5 Gbps, 10 Gbps, 20 Gbps, or 36 Gbps.

The Cisco ASR1000-ESP10-N is the nonencryption version of the Cisco ASR1000-ESP10. The Cisco ASR1000-ESP10-N can only support noncrypto Cisco IOS software images. It does not support encryption capabilities such as IPsec.

The Cisco ASR 1000 Series Routers support the following Cisco ASR 1000 Series Embedded Services Processors:

Features of the Cisco ASR 1000 Series Embedded Services Processors


Note The embedded services processor can be upgraded only on redundant embedded services processor systems (Cisco ASR 1006 Router and Cisco ASR 1013 Router). The Cisco ASR 1002 router supports only one Cisco ASR1000-ESP5 or ASR1000-ESP10. The Cisco ASR 1006 Router and Cisco ASR 1004 Router do not support the Cisco ASR1000-ESP5. When performing upgrades, the Cisco ASR1000-ESP10, Cisco ASR1000-ESP20, and any future ESPs can be upgraded.



Note Do not have different embedded services processors operating in the same chassis. The only time this condition occurs is when you are performing an upgrade.

Cisco ASR 1000-ESP200 and Third Generation Cisco QFP

Each Cisco ASR 1000-ESP200 uses 4 third generation Cisco QFPs (QFP-3rd-Gen) Application Specific Integrated Circuits (ASICs) to achieve maximum performance. Each QFP-3rd-Gen ASIC is mapped with a subset of SPA bays and interfaces (SIP). Through this mapping, the Cisco ASR 1000-ESP200 can perform all baseline packet routing operations such as Quality of Service (QoS) classification and IP multicasting. They can also perform Network Address Translation (NAT) tasks.

Figure 3-1 displays the SIP and SPA bays of the Cisco ASR 1013 Router and their mappings to the QFP-3rd-Gen ASICs.

Implications of SIP and SPA Slot Mapping

Interfaces and sessions that have an egress QoS have their schedules and queues present in the QFP-3rd-Gen ASIC that services the particular slot. Since there is a limitation of 29000 schedules and 116000 queues per QFP-3rd-Gen ASIC, multiple QFP-3rd-Gen ASICs should be targeted by placing the SIP and SPA in the correct order, in order to achieve full system scalability for schedules and queues.

For example, A 5xGE SPA supports more than 32000 point-to-point protocol (PPP) sessions depending on the ESP. However, if QoS is applied to these sessions, the QFP-3rd-Gen ASIC that supports the SIP and SPA slot can support only 29000 schedules, and these sessions share the 116000 queue limit. To support PPP sessions with QoS that are greater than 29000, a different SIP and SPA should be used to map to a different QFP-3rd-Gen ASIC. This will enable additional schedules and queues.

However, at 92 bytes and larger, the ASR1000-ESP40 outperforms ESP20. The difference at small packet sizes is a side-effect of optimizations made to achieve 40 Gbps for medium to large packets.



Note For supported hardware component configuration combinations, see Table 2-4.


The embedded services processor consists of a front panel label for indicator and control functions. The Cisco ASR 1000 Series Embedded Services Processor model number labeling is located next to the left card module handle. The module also contains card handles to assist in insertion or removal of the module. There are no front panel interfaces on the Cisco ASR1000-ESP modules.

Figure 3-3 displays the Cisco ASR 1000 Series Embedded Services Processor LEDS on the front panel.


Note The Cisco ASR 1000 Series embedded services processors have the same faceplate and status information except for the name label, such as Cisco ASR1000-ESP40, Cisco ASR1000-ESP20, Cisco ASR1000-ESP10, Cisco ASR1000-ESP10-N, and Cisco ASR1000-ESP5.

The ACTV LED indicates (in a redundant system) the embedded services processor board that is actively forwarding packets.

On the active embedded services processor board, the ACTV LED is green and the STBY LED is off. On the standby embedded services processor board, the STBY LED is yellow and the ACTV LED is off.

On Cisco ASR 1002 Router, Cisco ASR 1004 Router, and Cisco ASR 1002-F Router, the embedded services processor board is always active because these routers do not support redundancy. The Cisco ASR1000-ESP5 does not support redundancy. Therefore, it is always active.

STBY

Standby

Yellow

On a redundant system, the STBY LED indicates which embedded services processor is in the standby state and is waiting to take over packet forwarding in the event that the active embedded services processor experiences a failure. The STBY LED is in the off state while the active embedded services processor is in the on state.
