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.

New and Changed Information
•New Hardware Features in Release 15.4(1)S
•New Software Features in Release 15.4(1)S
•Modified Software Features in Release 15.4(1)S
New Hardware Features in Release 15.4(1)S
There are no new hardware features in Cisco IOS Release 15.4(1)S.
New Software Features in Release 15.4(1)S
The following features are supported from this release:
1588v2 Hybrid Clock
Effective with Cisco IOS Release 15.4(1)S, the PTP hybrid mode is supported for ordinary clock (in slave mode only) and boundary clock.
For more information about this feature, see PTP Hybrid Clock section of the Configuring Clocking feature guide at the following URL: http://www.cisco.com/en/US/docs/wireless/asr_901/Configuration/Guide/clocking.html
Dual REP Edge No-Neighbor
Effective with Cisco IOS release 15.4.(1)S, you can configure the non-REP switch facing ports on a single device as dual edge no-neighbor ports. These ports inherit all properties of edge ports, and overcome the limitation of not converging quickly during a failure.
For more information about this feature, see Configuring Resilient Ethernet Protocol feature guide at the following URL:
http://www.cisco.com/en/US/docs/wireless/asr_901/Configuration/Guide/rep.html
EoMPLS/TDM Pseudowire Redundancy over FRR
Effective with Cisco IOS Release 15.4(1)S, support was added for EoMPLS/TDM pseudowire redundancy over FRR.
For more information about this feature, see Remote Loop-Free Alternate - Fast Reroute feature guide at the following URL: http://www.cisco.com/en/US/docs/wireless/asr_901/Configuration/Guide/remote_lfa-frr.html
Ethernet Loopback - Internal Loopback on Bridge-Domain EFPs
Effective with Cisco IOS Release 15.4(1)S, the Cisco ASR 901 supports internal loopback on Bridge-domain EFPs.
For more information about this feature, see Configuring Ethernet OAM feature guide at the following URL:
http://www.cisco.com/en/US/docs/wireless/asr_901/Configuration/Guide/oam.html
IPv4 Multicast
Effective with Cisco IOS Release 15.4(1), IPv4 multicast is supported on the Cisco ASR 901 series routers. The router supports up to 500 multicast IP address entries.
The following featurettes are supported:
•Source Specific Multicast
•Source Specific Multicast (SSM) Mapping
•IGMP Version 1
•IGMP Version 2
•IGMP Version 3
For more information about this feature, see IPv4 Multicast on the Cisco ASR 901 Router feature guide at the following URL: http://www.cisco.com/en/US/docs/wireless/asr_901/Configuration/Guide/ipv4_mcast.html
IPv6 Multicast
Effective with Cisco IOS Release 15.4(1), IPv6 multicast is supported on the Cisco ASR 901 series routers.
The following featurettes are supported:
•IPv6 Multicast: Multicast Listener Discovery (MLD) Protocol, Versions 1 and 2
•IPv6 Multicast: PIM Source-Specific Multicast (PIM-SSM)
For more information about this feature, see IPv6 Multicast on the Cisco ASR 901 Router feature guide at the following URL: http://www.cisco.com/en/US/docs/wireless/asr_901/Configuration/Guide/ipv6_mcast.html
Extending QoS over MLPPP Interface
Effective with Cisco IOS Release 15.4(1)S, the QoS functionality on the MLPPP interface is extended to support:
•QoS for MPLS over MLPPP
•QoS for CPU generated traffic
For more information about this feature, see Configuring QoS feature guide at the following URL: http://wwww.cisco.com/en/US/docs/wireless/asr_901/Configuration/Guide/qos.html
Redundant PTP instances as per G.8265.1
PTP redundancy is an implementation on different clock nodes by which the PTP slave clock node interacts with multiple master ports such as grand master, boundary clock nodes, and so on.
A new servo mode is defined under PTP to support high PDV scenarios (when the PDVs exceed G.8261 standard profiles). You should use the servo mode high-jitter command to enable this mode on the PTP slave.
In servo mode, convergence time would be longer than usual, as this mode is meant only for frequency synchronization.
For more information about this feature, see PTP Redundancy section of the Configuring Clocking feature guide at the following URL: http://www.cisco.com/en/US/docs/wireless/asr_901/Configuration/Guide/clocking.html
REP over LAG
Effective with Cisco IOS Release 15.4(1)S, the Cisco ASR 901 supports REP over port-channel.
For more information about this feature, see Configuring Resilient Ethernet Protocol feature guide at the following URL:
http://www.cisco.com/en/US/docs/wireless/asr_901/Configuration/Guide/rep.html
SPAN
Local SPAN supports a SPAN session entirely within one switch. You can analyze network traffic passing through ports or VLANs by using SPAN to send a copy of the traffic to another port on the switch that has been connected to a network analyzer or other monitoring or security devices.
For more information about this feature, see Configuring Switched Port Analyzer feature guide at the following URL:
http://www.cisco.com/en/US/docs/wireless/asr_901/Configuration/Guide/span.html
Y.1564 over EVC CrossConnect
Effective with Cisco IOS release 15.4.(01)S, traffic can be generated over cross connect interface.
For more information about this feature, see Configuring Ethernet OAM feature guide at the following URL:
http://www.cisco.com/en/US/docs/wireless/asr_901/Configuration/Guide/oam.html
Support for "no service password recovery" command
Effective with Cisco IOS release 15.4.(01)S, support was added for the "no service password recovery" command.

Resolved Caveats
This section provides information about the resolved caveats for the Cisco ASR 901 router running Cisco IOS Release 15.4(1)S.
Bug ID
|
Description
|
CSCue91862
|
Peering is not working for untagged EVC when service instance is configured with default encapsulation.
|
CSCuh11698
|
When more than four ports are connected to a peer where the ports are administratively up, the interface which detects a link up event takes the license first. Hence, the behavior of ports is non predictable. The first port which detects the link up will take the license and the other port may not get a valid license.

|
When you insert CWDM or avago type fiber adjacent to GLC-LH-SMD port, the GLC-LH-SMD port goes down.
