The IOS XE 3.6(1)S Release for the Cisco ASR 903 Router does not introduce any new hardware features.
New Hardware Features in Cisco IOS XE Release 3.6S
The IOS XE 3.6(0)S Release for the Cisco ASR 903 Router introduces support for the following hardware features:
- New SFP modules—This release introduces support for the following SFP modules:
– 1000M SFP-DWDM-SFP
– 1000M SFP-CWDM
– 1000M SFP - GLC-ZX-SMD
– 1000M SFP - GLC-SX-MMD
– 1000M SFP - GLC-LH-SMD
- 4-Port OC3/STM-1 or 1-Port OC12/STM-4 Interface Module—This release introduces support for the A900-IMA4OS interface module. This combo module supports one of four modes: 4xOC3, 4xSTM-1, 1xOC12, and 1xSTM-4. The module supports SDH framing and HDLC encapsulation.
Note The A900-IMA4OS Interface Module requires a license for use. For more information about supported licenses, see Software Licensing Overview.
Note IOS XE Release 3.6 for the offers a limited set of software features for the A900-IMA4OS Interface Module. For more information, see http://www.cisco.com/en/US/docs/wireless/asr_900/software/guide/chassis/Release3.6.0S/ASR903-Chassis-SW-36.html
New Software Features in Cisco IOS XE Release 3.6(2)S
The IOS XE 3.6(2)S Release for the Cisco ASR 903 Router does not introduce any new software features.
New Software Features in Cisco IOS XE Release 3.6S
The following are the new software features introduced in Cisco IOS XE Release 3.6S:
NoteMany of the features supported on the Cisco ASR 903 Router require a license for use. For more information about supported licenses, seeSoftware Licensing Overview.
- Any Transport over MPLS (AToM)—ATM AAL5 over MPLS (AAL5oMPLS)—The AAL5 Transport over MPLS feature provides an ATM permanent virtual circuit (PVC) transport service for transporting AAL5 PDUs across an IP/MPLS backbone with rate-limit policing and configurable PVC priority value. A dynamic MPLS tunnel is configured to enable label imposition and disposition of encapsulated ATM PDUs transported between two edge routers having a Label Distribution Protocol (LDP) neighbor relationship. For details about this feature, see:
- CFM over EFP interface with xconnect—This feature provides support for IEEE 802.1ag draft 8.1-compliant CFM functionality on pseudowire & VFI interfaces. For details about this feature, see:
- CFM on Port-Channel Interfaces—This feature provides support for IEEE 802.1ag (CFM) on port-channel interfaces for end-to-end connectivity fault management on Ethernet networks. For details about this feature, see:
- IPv6 Quality of Service Classification—This feature allows you to define traffic classes, create and configure traffic policies (policy maps), and attach those traffic policies to interfaces. The Cisco ASR 903 Router supports classification of IPv6 traffic based on DSCP or Precedence values on ingress and egress interfaces. For details about this feature, see
- IPv6 Quality of Service Marking—This feature introduces support for marking IPv6 traffic with DSCP or Precedence values. IPv6 QoS is supported on ingress and egress interfaces. For details about this feature, see
- ISIS IPv4 Loop Free Alternate Fast ReRoute (LFA FRR) for VPLS Core—IPFRR (IP Fast ReRoute) is a set of technologies used in order to rapidly converge traffic flows around link and/or node failures. For details about this feature, see http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_pi/configuration/xe-3s/asr903/iri-xe-3s-asr903-book/iri-lfa-frr.html
- ITU-T G.8032 Ethernet Ring Protection Switching—This feature implements protection switching mechanisms for Ethernet layer ring topologies. This feature uses the G.8032 Ethernet Ring Protection (ERP) protocol, defined in ITU-T G.8032, to provide protection for Ethernet traffic in a ring topology, while ensuring that there are no loops within the ring at the Ethernet layer. The loops are prevented by blocking either a pre-determined link or a failed link. For details about this feature, see http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/lanswitch/configuration/xe-3s/asr903/lanswitch-ethernet-channel-xe-3s-asr903-book/lsw-cfg-rep.html
- L2 ACL on Service Instance—This is a security feature which customers can apply to an EVC interface to filter packets based on their MAC address. For details about this feature, see http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/cether/configuration/xe-3s/asr903/b_layer2_ASR903/ly2-acl-evc.html
- L2PT - Layer 2 Protocol Tunneling on Trunk Ports—Layer 2 protocol tunneling makes control protocol PDUs such as STP, CDP, and VTP, transparent to the service provider cloud when passing traffic through trunk ports. For details about this feature, see http://www.cisco.com/en/US/docs/ios-xml/ios/wan_lserv/configuration/xe-3s/wan-lserv-xe-3s-book.html
- MLPPP - Multilink PPP—Multilink PPP (also referred to as MP, MPPP, MLP, or Multilink) provides a method for spreading traffic across multiple physical WAN links and is described in RFC1990. For details about this feature, see:
Note Limitations apply when configuring MLPPP. For more information, see Chapter10, “Restrictions and Caveats in Cisco IOS XE 3.6S Releases”
- Y.1731 Performance Monitoring—Y.1731-PM provides a standards-based Ethernet performance monitoring function, which encompasses measurement of Ethernet frame delay, frame delay variation, frame loss, and frame throughput as outlined in the ITU-T Y-1731 specification and interpreted by the Metro Ethernet Forum (MEF) standards group.
