Centralized network timing. Control plane and data plane elements. The Cisco® ASR 900 Route Switch Processor (RSP) is the powerful centralized engine that provides these features and more for Cisco ASR 900 Series routers. The Cisco ASR 900 RSP (Figure 1) is designed to address the requirements of converged service provider networks - from Carrier Ethernet technologies to advanced services such as Multiprotocol Label Switching (MPLS). It helps providers add innovative traffic management and intelligent packet switching and routing features.

Route Switch Processor Features

The Cisco ASR 900 RSP module contains separate control plane and data plane components. These include the main control plane CPU for the Cisco IOS® XE operating system and platform control software. The data plane packet processing and traffic management is performed by the Cisco Carrier Ethernet application-specific integrated circuit (ASIC).

Cisco Carrier Ethernet ASIC

Powered by the Cisco Carrier Ethernet ASIC and designed specifically for the needs of service providers, the Cisco ASR 900 Series routers deliver essential Carrier Ethernet technologies. These include hierarchical quality of service (HQoS), IPv4, IPv6, MPLS, and Hierarchical Virtual Private LAN Services (HVPLS). The Cisco Carrier Ethernet ASIC provides line-rate performance and supports advanced services including access control list (ACL) and HQoS without affecting performance. The ASIC incorporates innovative traffic management capabilities while providing intelligent packet switching and routing operations.

Service Enhancement

With Cisco ASR 900 Series routers, each service is assigned enhanced QoS and security attributes. The router provides advanced per-traffic-class metering and offers bidirectional packet count and byte count statistics. The service offering is enhanced with operations, administration, and maintenance (OAM) functionality that includes Layer 2 Connectivity Fault Management (CFM), IP service-level agreement (IP SLA) for Layer 3, and MPLS OAM.

Service Scale

The Cisco ASR 900 Series delivers flexible service scalability in a small footprint. The routers deliver high performance and high scale for point-to-point and multipoint VPN services. The HQoS capabilities of the Cisco ASR 900 Series scale to eight queues per service, three levels of scheduling, and buffer sizes capable of accommodating today’s most demanding wireline and wireless applications.

Clocking and Timing Services

The Cisco ASR 900 RSPs contain the central system clocking and timing functions for the Cisco ASR 900 Series platform, which are required in a modern unified network. The RSPs offer integrated support for the Building Integrated Timing Supply (BITS), 10 MHz, 1 Pulse Per Second (1 PPS) and Time Of Day (TOD) interfaces. The Cisco ASR 900 Series platform also supports synchronous Ethernet (SyncE), IEEE 1588-2008, and can act as the clock source for network clocking of time-division multiplexing (TDM) and Synchronous Digital Hierarchy/Synchronous Optical Network (SDH/SONET) interfaces.

The Cisco ASR 900 Series can act as an IEEE 1588-2008 Ordinary Clock, Boundary Clock, end-to-end Transparent Clock, and Master Clock function in an IEEE 1588-2008 timing domain.

High Availability and Modularity

The Cisco ASR 900 Series router is a fully modular platform. The design of the router delivers optional intra-chassis hardware redundancy for all hardware components and supports software redundancy with In Service Software Upgrade (ISSU) support when a pair of route switch processors is inserted in the Cisco ASR 903 Router chassis.

With two RSPs inserted in the Cisco ASR 903 Router, one RSP operates in active mode and the other RSP operates in hot standby mode. The Cisco ASR 900 RSP is a field replaceable unit (FRU) and can be online inserted and removed (OIR) while the Cisco ASR 903 Router system is operating. The removal or failure of the active RSP in the Cisco ASR 903 Router results in the automatic switchover to the standby RSP.

Management Interfaces

The Cisco ASR 900 RSP contains the out of band (OOB) management interfaces for the system. To offer flexibility to access the router, there are a variety of interfaces for management access to the platform. This includes a dual-mode console port that functions as either a USB console or a serial console port. In addition to the serial console access, the Cisco ASR 900 RSP contains an Ethernet management port that has no interaction with the actual Carrier Ethernet ASIC traffic. In addition to the OOB control interfaces, there is a USB port to connect USB Flash devices for loading Cisco IOS XE Software images and configurations on the platform.

Ethernet Interface Modules and Multiservice Interface Modules

The Cisco ASR 903 Route Switch Processor 1 (RSP1) is compatible with the following interface modules.

   Cisco ASR 900 Series 1-Port 10GE XFP Module: supports a single 10-Gigabit Ethernet Small Form-Factor Pluggable (XFP) port.

   Cisco ASR 900 Series 8-Port 1GE RJ45 Module: supports eight Copper RJ-45 Gigabit Ethernet ports.

   Cisco ASR 900 Series 8-Port 1GE SFP Module: supports eight Gigabit Ethernet Small Form-Factor Pluggable (SFP) ports.

   Cisco ASR 900 Series 14-Port Serial Module: supports 14 serial ports. The 14 ports are comprised of six 12-in-1 Connectors with support for Asynchronous RS-232 interfaces using EIA/TIA-232 DB-25 connectors and two 68-Pin Connectors which support up to 8 RS-232 and RS-485 interfaces in full or half duplex mode using 4 RS-232 connectors (DB-25, DB-9, or RJ-45).

   Cisco ASR 900 Series 16-Port T1/E1 Module: supports 16 T1 or E1 ports. The port type is software configurable per interface module; mixing of T1 and E1 ports on a single interface module is not supported.

   Cisco ASR 900 Series 4-Port OC3/STM1 or 1-Port OC12/STM4 Module: This combination module is designed to be software configurable in four modes: 4xOC-3, 4xSTM-1, 1xOC12, and 1xSTM-4. If the module is configured for 4xOC-3 or 4xSTM-1, then the individual interfaces can be configured to be clear-channel, POS, or channelized in any combination. Support of these modes is software dependent as described in the Cisco IOS XE Software for Cisco ASR 900 Series Router data sheet.

The Cisco ASR 900 RSP2 is compatible with all of the Interface modules that are supported by the Cisco ASR 903 Route Switch Processor 1 (RSP1). In addition, this second generation RSP is compatible with the following interface modules.

   Cisco ASR 900 Series 2-Port 10GE XFP/SFP+ Module: This module supports two 10-Gigabit Ethernet ports. Each port can individually be used as either a Small Form-Factor Pluggable (XFP) port or as a Small Form-factor Pluggable Plus (SFP+) port.

   Cisco ASR 900 Series 8-Port 1GE RJ45 and 1-port 10GE SFP+ Module: supports eight Copper RJ-45 Gigabit Ethernet ports and one Small Form-factor Pluggable Plus (SFP+) port.

   Cisco ASR 900 Series 8-Port 1GE SFP and 1-port 10GE SFP+ Module: supports eight Gigabit Ethernet Small Form-Factor Pluggable (SFP) ports and one Small Form-factor Pluggable Plus (SFP+) port.

   Cisco ASR 900 Series 8-Port T1/E1 Module: supports 8 T1 or E1 ports. The port type is software configurable per interface module; mixing of T1 and E1 ports on a single interface module is not supported.

   Cisco ASR 900 Series 32-Port T1/E1 Module: supports 32 T1 or E1 ports. The port type is software configurable per interface module; mixing of T1 and E1 ports on a single interface module is not supported.

The Cisco ASR 900 interface module support is dependent on the combination of the RSP, the chassis, software version and the interface module slot combination. The Cisco ASR 900 Series Aggregation Services Router Interface Modules Datasheet contains the compatibility matrix for the various combinations.

Software

The Cisco ASR 900 Series Router is supported in Cisco IOS XE S software, a modular operating system. Cisco IOS XE Software is designed to provide modular packaging, feature velocity, and powerful resiliency. The software supports Cisco software activation on the Cisco ASR 900 Series Router. Table 1 describes the Cisco IOS XE universal consolidated packages supported on the router. The functionality is established through the appropriate technology package licenses. The available features and related licensing are described in the Cisco IOS XE Software for Cisco ASR 900 Series router data sheet.
