  • PPP MRRU Negotiation Configuration—Introduces support for the ppp multilink mrru command, which allows you to specify a Maximum-Receive-Reconstructed-Unit (MRRU) value on MLP interfaces and member links after a change in the MTU value on the interface. For details about this feature, see http://www.cisco.com/en/US/docs/ios/dial/configuration/guide/dia_pppmlp_mrru_neg.html .
  • ACFC and PFC Support on Multilink Interfaces—Using the Address and Control Field Compression (ACFC) and PPP Protocol Field Compression (PFC) Support on Multilink Interfaces feature, you can control the negotiation and application of the Link Control Protocol (LCP) configuration options for ACFC and PFC.

This release introduces support for ACFC and PFC support on serial interfaces on the T1/E1 and optical interface modules. This feature includes support for the following commands:

ppp acfc local { request | forbid }

ppp acfc remote { apply | reject | ignore }

ppp pfc local { request | forbid }

ppp pfc remote { apply | reject | ignore }

For more information about configuring ACFC and PFC, see the following documents

  • Egress QoS policies on main physical interface for port shaping + H-policies on EFP—Previous releases did not support QoS policies on interfaces configured with an Ethernet Flow Point (EFP) or port-channel member links with EFPs. This release introduces support for hierarchical QoS policies on EFP interfaces. For more information about how to configure QoS on EFP interfaces, see

http://www.cisco.com/en/US/docs/wireless/asr_900/software/guide/chassis/Release3.6.0S/ASR903-Chassis-SW-36.html

  • Switch Port Analyzer—Release 3.6.1 introduces support for Switch Port Analyzer (SPAN) on physical interfaces. The following commands are supported:

monitor session {session_number} {source {interface slot/port}} [, | - | rx | tx | both]

monitor session {session_number} {destination {interface type/num} [, | - ]}

For more information about SPAN, see http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/cether/configuration/xe-3s/asr903/b_layer2_ASR903/ly2-span-rspan.html

  • Support for MPLS Labels with PTP traffic- This release introduces support for MPLS labels with PTP Delay-Request packets. The following encapsulation types are supported:

VPN

BGP IPv4

LDP

FRR

The router adds time stamps to MPLS-encapsulated PTP packets by default.

  • Reverse Path Forwarding failure handling—This release introduces support for the platform multicast rpf_fail_handling enable command. The Cisco ASR 903 Router hardware does not handle RPF fail packets default; you can use this command to enable RPF fail packets handling.

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:
