Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Centralized network timing. Control plane and data plane elements. The Cisco® ASR 900U Route Switch Processor (RSP) is the powerful centralized engine that provides these features and more for Cisco ASR 900U Series routers. The ASR 900U Series RSPs (Figure 1) address the requirements of a converged Wide Area Network (WAN), from Carrier Ethernet technologies to advanced services such as Multiprotocol Label Switching (MPLS). The Cisco ASR 900U Series Route Switch Processor 2 (RSP2A) helps Industrial Internet of Things (IIoT) network providers add innovative traffic management and intelligent packet-switching and routing features and continue to support mission-critical operation technology systems through circuit-oriented services.

Product Overview

The Cisco ASR 900U Series RSP modules contain separate control plane and data plane components. These include the main control plane CPU for the Cisco IOS^® Software operating system and platform control software. The data-plane packet processing and traffic management are performed by the Carrier Ethernet Application-Specific Integrated Circuit (ASIC).

Features and Benefits

Feature	Benefit
Carrier Ethernet ASIC	Delivers essential Carrier Ethernet technologies such as Hierarchical Quality of Service (HQoS), IPv4, IPv6, MPLS/FlexLSP, and Hierarchical Virtual Private LAN Services (HVPLS). It provides line-rate performance and incorporates innovative traffic management capabilities while providing intelligent packet switching and routing operations.
Service enhancement	Provides advanced per-traffic-class metering and offer 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 Agreements (IP SLAs) for Layer 3, and MPLS OAM.
Service scale	Provides flexible service scalability in a small footprint delivering high performance and scale for point-to-point and multipoint services, accommodating the requirements from the most demanding wireline and wireless applications.
Clocking and timing services	Offers integrated support for the Global Navigation Satellite System (GNSS), Building Integrated Timing Supply (BITS), 10 MHz, 1 Pulse Per Second (1 PPS), and Time Of Day (TOD) interfaces, crucial functions required in a modern unified network. As the central system clocking and timing functions for the ASR 900U Series platform, the Cisco ASR 900U RSPs support Synchronous Ethernet (SyncE) and IEEE 1588-2008 and can act as the clock source for network clocking of Time-Division Multiplexing (TDM) and SDH/SONET interfaces. The ASR 900U Series can act as an IEEE 1588-2008 ordinary clock, boundary clock, end-to-end transparent clock, and primary clock function in an IEEE 1588-2008 timing domain.
High availability and modularity	Delivers optional intrachassis 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 900U system chassis fully modular platform. With two RSPs inserted in the Cisco ASR 903U, one RSP operates in active mode, and the other RSP operates in hot standby mode. The Cisco ASR 900U RSP is a Field-Replaceable Unit (FRU), and it can be Online Inserted and Removed (OIR) while the Cisco ASR 900U system is operating. The removal or failure of the active RSP in the Cisco ASR 900U system results in the automatic switchover to the standby RSP.
Management interfaces	Contains the Out-Of-Band (OOB) management interfaces for the system. To offer flexible access to the router, a variety of interfaces are available for management access to the platform, including 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 900U RSP contains an Ethernet management port that has no interaction with actual Carrier Ethernet ASIC traffic. In addition to the OOB control interfaces, a USB port can connect USB flash devices for loading Cisco IOS Software images and configurations on the platform.

Fully Distributed and Unique Packet/Circuit Capabilities for Converged Access Networks

The Cisco ASR 902U/903U Route Switch Processor 2 (RSP2A) 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.

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 900U Series Router data sheet.

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

● Cisco ASR 900U Series 8-Port 1GE RJ45 and 1-port 10GE SFP+ Module: Supports eight copper RJ-45 Gigabit Ethernet ports and one SFP+ port.

● Cisco ASR 900 Series 6-port E&M Module: Supports six E&M interfaces.

The ASR 900U interface module support is dependent on the combination of the RSP, the chassis, software version, and the interface module slot. The Cisco ASR 900U Series interface modules datasheet at https://www.cisco.com/c/en/us/products/collateral/routers/asr-903-series-aggregation-services-routers/datasheet-c78-738338.html contains the compatibility matrix for the various combinations.
