ATM IMA on OC-3 Interfaces—This release introduces support for ATM IMA on the OC-3 interface module. For more information about this feature, see the Cisco ASR 903 Router Chassis Configuration Guide, Release 3.8 .
BFD Support on TDM interfaces—Release 3.8 introduces support for BFD on TDM interfaces. This feature does not introduce any new CLI.
BFD Timer Improvements—Release 3.8 introduces support for 3.3ms timers for offloaded IPv4 BFD traffic.
BGP PIC—This release introduces support for BGP Prefix-Independent Convergence (PIC). This feature improves BGP convergence after a network failure. This convergence is applicable to both core and edge failures and can be used in both IP and MPLS networks. The BGP PIC Edge for IP and MPLS-VPN feature creates and stores a backup/alternate path in the routing information base (RIB), forwarding information base (FIB), and Cisco Express Forwarding so that when a failure is detected, the backup/alternate path can immediately take over, thus enabling fast failover.

MPLS on PoS Interfaces—Release 3.8 introduces support for MPLS on Packet over SONET (PoS) interfaces. For more information about this feature, see the Cisco ASR 903 Router Chassis Configuration Guide, Release 3.8 .
MPLS-TP MIB—This release introduces support for the MPLS-TP MIB. For more information about using MIBs, see MIB Support.
Network Virtualization Service—This Release introduces support for the Satellite Network Virtualization (nV) service or the Satellite Switching System, which enables you to configure a topology in which satellite devices complement one or more Cisco ASR 9000 Series routers in order to collectively realize a single virtual switching system. In this system, the satellite switches act under the management control of the Cisco ASR 9000 Series Aggregation Services Routers. The complete configuration and management of the satellite chassis and features is performed through the control plane and management plane of the Cisco ASR 9000 Series Router. For more information about how to configure nV on the ASR 9000 and the satellite devices, see http://www.cisco.com/en/US/partner/docs/routers/asr9000/software/asr9k_r4.2/interfaces/configuration/guide/hc42satl.html
Packet over SONET—This release introduces support for Packet over SONET (PoS) interfaces on the OC-3 interface module. For more information on how to configure PoS interfaces, see the Cisco ASR 903 Chassis Configuration Guide, Release 3.8 .
QoS on PoS Interfaces—Release 3.8 introduces support for QoS features on egress PoS interfaces using MLPPP bundles. For more information about configuring QoS on MLPPP interfaces, see the Cisco ASR 903 Chassis Configuration Guide, Release 3.8.
QoS Features—Release 3.8 introduces support for the following QoS features:
– queue-limit percent command— Allows you to specify the queue limit (size) for a class in as a percentage value.
– Higher Queue Limit Size— Release 3.8 extends the maximum byte value queue-limit-size argument used with the queue-limit command. The previous maximum value was 491520 bytes; the new value is 2 MB.
– Release 3.8 enhances the show policy-map interface command to display the default queue-limit.
For more information about the Release 3.8 QoS features, see the QoS chapter of the Cisco ASR 903 Chassis Configuration Guide, Release 3.8.
SONET Mode—This release introduces support for SONET mode on the OC-3 interface module. For more information on how to configure PoS interfaces, see the Cisco ASR 903 Chassis Configuration Guide, Release 3.8 .
Telecom Profile Support—Release 3.8 introduces support for telecom profiles, which allow you to configure a network clock to use the G.8265.1 recommendations for establishing PTP sessions, determining the best master clock, handling SSM, and mapping PTP classes. For information about how to configure telecom profiles, see the Cisco ASR 903 Chassis Configuration Guide, Release 3.8.
Trunk EFPs on Port-Channel Interfaces—This release adds support for trunk EFPs on port-channel interfaces, as shown in the following configuration:
