OL-30118-01
This release notes is for the Cisco ASR 901 Series Aggregation Services Router for Cisco IOS Release 15.3(3)S and contains the following sections:
Introduction
The Cisco ASR 901 Series Aggregation Services Router is a cell-site access platform specifically designed to aggregate and transport mixed-generation radio access network (RAN) traffic. The router is used at the cell site edge as a part of a 2G, 3G, or 4G RAN.
The Cisco ASR 901 router helps enable a variety of RAN solutions by extending IP connectivity to devices using Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), Node Bs using High Speed Packet Access (HSPA) or Long Term Evolution (LTE), base transceiver stations (BTSs) using Enhanced Data Rates for GSM Evolution (EDGE), Code Division Multiple Access (CDMA), CDMA-2000, EVDO, or WiMAX, and other cell-site equipment.
It transparently and efficiently transports cell-site voice, data, and signaling traffic over IP using traditional T1 and E1 circuits, as well as alternative backhaul networks such as Carrier Ethernet and DSL, Ethernet in the First Mile (EFM), and WiMAX. It also supports standards-based Internet Engineering Task Force (IETF) Internet protocols over the RAN transport network, including those standardized at the Third-Generation Partnership Project (3GPP) for IP RAN transport. Custom designed for the cell site, the Cisco ASR 901 router features a small form factor, extended operating temperature, and cell-site DC input voltages.
Table 1 lists the Cisco ASR 901 router model versions.

This section describes new and changed features in Cisco IOS Release 15.3(3)S.
DWDM SFP+
Support was added for Dense Wavelength Division Multiplexing (DWDM) SFP+ on the Cisco ASR 901 10G series routers. This module provides scalable and easy-to-deploy 10-Gigabit LAN, WAN, and Optical Transport Network (OTN) services. It supports 40 non-tunable ITU 100-GHz wavelengths and provides digital optical monitoring capability. For detailed information about this feature, see the following document:

New Software Features in Release 15.3(3)S
The following features are supported from this release:
Autonomic Networking
Autonomic networking makes devices more intelligent and simplifies the interface between the operator and Network Management System (NMS) system, by providing a strong abstraction across the network, distributed on each device. It also automatically provides all relevant best practices, and keeps them up to date, without the need for human intervention. For detailed information about this feature, see the following document:
http://www.cisco.com/en/US/docs/ios-xml/ios/auto_net/configuration/15-s/an-auto-net-15-s-book.html
Storm Control
The Storm Control feature prevents traffic on a LAN from being disrupted by a broadcast, multicast, or unknown unicast storm on one of a port. For detailed information about this feature, see the following document:
http://www.cisco.com/en/US/docs/wireless/asr_901/Configuration/Guide/storm_control.html
Egress Policing
Egress policing can be classified based on QoS-groups, DSCP, and precedence value. For QoS-groups to work at egress, you should map the traffic at ingress to a specific QoS-group value. For detailed information about this feature, see the following document:
http://www.cisco.com/en/US/docs/wireless/asr_901/Configuration/Guide/qos.html
MPLS Traffic Engineering (TE) —Fast Reroute (FRR) Link Protection
Support for CESoPSN, SAToP, and ATM/IMA was added from Cisco IOS Release 15.3(3)S onwards. For detailed information about this feature, see the following document:
http://www.cisco.com/en/US/docs/wireless/asr_901/Configuration/Guide/mpls_te-frr.html
Multiaction Ingress Policer on EVC
Effective with Cisco IOS Release 15.3(3)S, the Cisco ASR 901 supports policing ingress traffic over the cross connect EVC, similar to bridge domain service policy. For detailed information about this feature, see the following document:
http://www.cisco.com/en/US/docs/wireless/asr_901/Configuration/Guide/qos.html
Y.1731 Performance Monitoring
Effective with Cisco IOS Release 15.3(3)S, the Cisco ASR 901 router supports ITU-T Y.1731 performance monitoring on the following interfaces:
–SLM support on the EVC cross connect
–SLM support on the Port-Channel EVC cross connect
–DMM and SLM support on the EVC BD for both the up and down MEPs
