Cisco IOS XE Software for Cisco ASR 920 Series Aggregation Services Routers Data Sheet
Available Languages
Cisco IOS® Software is continuously evolving to provide you with the features of higher quality. Cisco IOS® Software software provides modular structure for
Cisco ASR920 Series Aggregation Services Routers which allows separation of the data plane and the control plane thereby enhancing the performance of the system.
Cisco IOS XE Software on the Cisco ASR 920 Router (Figure 1) includes licenses for Metro Access, Metro
IP Access, and Advanced Metro IP access. These feature sets can be activated as needed, allowing “pay as you grow” model.
Software Releases and Options
Cisco IOS XE Software for ASR 920 routers provides modular packaging, so you can buy just the software features you need. And as with all Cisco IOS Software, the code is divided into separate modules, so you can update them separately to get new features more quickly. Cisco IOS XE Software also provides powerful resiliency. ASR 920 routers are supported as of Cisco IOS XE Software Release 3.13.0S.
Consolidated Software Packages
Consolidated software packages contain a superset of all features. The individual feature sets can be activated once the correct feature licenses are applied to the router. Table 1 describes the two Cisco IOS XE universal consolidated packages supported on the ASR 920 Router and the functionality supported in this universal image. The functionality is enforced through the appropriate technology package licenses.
Table 1. Universal Cisco IOS XE Software Consolidated Package for Cisco ASR 920 Routers
| Cisco IOS XE Consolidated Package | Part Number | Description |
| Cisco ASR 920 Series IOS XE - No Payload Encryption | SASR920NPEK9S | ● Provides a consolidated package ● Offers basic feature support without a license, including Secure Shell (SSH) and SNMPv3 support |
Flexible Software Activation
Cisco ASR 920 routers support the Cisco IOS software activation feature. With this capability, Cisco IOS Software feature sets can be activated with software licenses, supporting an “pay as you grow” model. This model allows service providers to invest in software resources only when their businesses need them. All software licenses for Cisco ASR 920 routers are available on a per-chassis basis. ASR 920 routers offer three Cisco IOS Software licenses:
● Metro Access License: Offers advanced quality of service (QoS), Carrier Ethernet Layer 2 features, Synchronous Ethernet (SyncE), and Ethernet operations, administration, and maintenance (OAM) capabilities.
● Metro IP Access License: Offers all capabilities of the Metro Access license with the addition of IEEE 1588-2008 Ordinary Clock and Transparent Clock, Bidirectional Forwarding Detection (BFD), Layer 3 features for advanced IP routing protocols, multi-VPN routing, and Layer 3 Multicast and Forwarding Customer Edge (multi-VRF CE) capabilities.
● Advanced Metro IP Access License: Adds the following capabilities to the Metro IP Services license: Multiprotocol Label Switching Transport Profile (MPLS-TP); MPLS, Ethernet over MPLS (EoMPLS), Circuit Emulation Service over Packet Switched Network (CESoPSN), and Structure Agnostic TDM over Packet (SAToP) pseudowires; Multirouter Automatic Protection Switching (MR-APS); Multichassis Link Aggregation and Control Protocol (mLACP); MPLS traffic engineering (MPLS TE); MPLS Fast Reroute (MPLS FRR); and MPLS VPN support.
Table 2 lists the main features in the Cisco IOS Software licenses for ASR 920 routers. Feature availability is dependent on software release and implementation schedule.

Additional Feature Licenses
The following two additional Cisco IOS licenses are used to activate new software functionality for Cisco ASR 920 routers, in addition to feature set capabilities.
● OC3 port license: Allows service providers to activate OC3 ports on the Cisco ASR 920 router,
One license is required for each OC3 port. The A900-IMA4OS IM supports four OC3 ports.
● IEEE 1588-2008 BC/MC license: Allows service providers to activate IEEE 1588-2008 Boundary Clock (BC) or Master Clock (MC), or both, when required. One license is required for each chassis that needs
to activate IEEE 1588-2008 BC or MC functionality in the system.
Cisco IOS XE Release Schedule
The Cisco IOS XE software delivery schedule allows customers to qualify releases more quickly and have a definitive release schedule for new software images. This schedule includes:
● Time-based releases: Releases are planned for delivery every four months. New software features and hardware are introduced in each release. Releases have fewer incremental features included when compared with traditional Cisco IOS Software releases, reducing customer qualification time.
● Two release support durations: Each Cisco IOS XE Software release is classified as either a Standard Support or Extended Support release. A Standard Support release has a total engineering support lifetime of one year, with two scheduled rebuilds. The Extended Support release provides a total engineering support lifetime of two years, with four scheduled rebuilds. For more information about the Cisco IOS XE Software end-of-life policy and associated support milestones for specific software releases, visit http://www.cisco.com.
● Rebuilds scheduled at regular intervals: Rebuilds are created only for bug fixes, and no new features are included in a rebuild image. For Standard Support releases, the first rebuild image is released two months after the parent image’s first customer shipment (FCS). The second rebuild image is released four months after the parent image’s FCS. The Extended Support release provides four scheduled rebuilds. The first two rebuilds are released at two-month intervals after FCS of the affected Cisco IOS XE Software release, and the second two rebuilds are released at four-month intervals thereafter. Releases to correct critical problems (such as those identified by the Cisco Product Security Incident Response Team) are introduced as needed.
