Invalid Flag attribute in performance monitoring data (PMON)

A new attribute, "Invalid," is introduced in the PMON data in the show controller output. The "Invalid" flag associated with Near End and Far End datasets indicates that the dataset is not valid and shouldn't be considered for performance analysis.

Frame Relay Configuration extended to RSP2 Module

You can configure frame relay on the iMSG serial interface for the following interface modules:

• 1-port OC-48/STM-16 or 4-port OC-12/OC-3 / STM-1/STM-4 + 12-port T1/E1 + 4-port T3/E3 CEM interface module

Multilink Frame Relay (MFR) for IP Interworking

You can configure MFR encapsulation on serial interface for IPv4 and IPv6 interworking for the following interface modules:

• 1 port OC-48/STM-16 or 4 port OC-12/OC-3 / STM-1/STM-4 + 12 port T1/E1 + 4 port T3/E3 CEM Interface Module

  (A900-IMA3G-IMSG)

• 1-Port OC-192 or 8-Port Low Rate CEM 20G Bandwidth Interface Module

  (A900-IMA1Z8S-CXMS)

Multiple physical interfaces can be combined into a single bundle, and this frame relay interface supports more bandwidth than that is available from any single physical interface. The ease to add or remove physical interfaces dynamically so that you can modify the total bandwidth available on that interface. The resilience that is provided when multiple physical interfaces are provisioned on a single bundle so that when some of the physical interfaces fail, the bundle continues to support the frame relay service.

  (A900-IMA3G-IMSG)

• 1-Port OC-192 or 8-Port Low Rate CEM 20G Bandwidth Interface Module

  (A900-IMA1Z8S-CXMS)

• 1-port OC-192 or 8-port low rate CEM 20G bandwidth interface module

Frame Relay being a streamlined protocol facilitates higher performance and greater efficiency.

GR-820-CORE Performance Monitoring

The show controller tabular command enables you to view the performance monitoring details in tabular form as per GR-820-Core standards.

MLPPP IP Termination on all Serial Physical and Logical Interfaces

This release supports Layer 3 termination using IPv6 addressing on MLPPP interfaces for the 1 port OC-48/STM-16 or 4 port OC-12/OC-3 / STM-1/STM-4 + 12 port T1/E1 + 4 port T3/E3 CEM interface module. In releases earlier, with IPv4 addressing, you can scale up to 512 MLPPP bundles. Now with IPv6 addressing, the MLPPP bundles can be scaled up to 1024.

Unframed Framing Support on E1 and Channel STM links

In this release, a new framing mode unframed is supported for the 1 port OC-48/STM-16 or 4 port OC-12/OC-3 / STM-1/STM-4 + 12 port T1/E1 + 4 port T3/E3 CEM Interface Module. With the unframed mode, you can create serial interfaces under the electrical E1 mode.

CEM and IP IW Feature Parity for A900-IMA1Z8S-CXMS and A900-IMA3G-IMSG Interface Modules

• APS and non-APS Support—APS and non-APS support for SDH and SONET for iMSG IPv6 interworking

• NxDS0 iMSG IPv4—NxDS0 iMSG IPv4 and NxDS0 APS iMSG IPv4

• UPSR IPv6—UPSR IPv6

VLAN handoff supports IPv4 and IPv6 local connect and cross connect.

Cisco IOS XE Amsterdam 17.3.1

ACR and DCR Scale Support

Adaptive Clock Recovery (ACR) and Differential Clock Recovery (DCR) are techniques used for Circuit Emulation (CEM) to recover clocks on the Cisco RSP3 module.

IPv4 Interworking Support for MLPPP Interfaces

The Multilink Point-to-Point (MLPPP) interworking supports IPv4 Layer 2 VPN Interworking with T1 or E1 bundles on the Cisco RSP3 module. The MLPPP interworking enables service providers (offering relatively low-speed links) to use MLP and spread traffic across them in their MPLS networks. The MPLS Multilink PPP feature reduces the number of Interior Gateway Protocol (IGP) adjacencies and facilitates load sharing of traffic.

IPv6 Interworking Support for MLPPP Interfaces

The Multilink Point-to-Point (MLPPP) interworking supports IPv6 Layer 2 VPN Interworking with T1 or E1 bundles on the Cisco RSP3 module. The MLPPP interworking enables service providers (offering relatively low-speed links) to use MLP and spread traffic across them in their MPLS networks. The MPLS Multilink PPP feature reduces the number of Interior Gateway Protocol (IGP) adjacencies and facilitates load sharing of traffic.

IPv6 Interworking Pseudowire Support on HDLC or PPP Serial Interfaces

The IPv6 interworking is supported for Layer 2 VPN interworking mode. The IPv6 interworking is supported only for HDLC or PPP to Ethernet. Layer 3 termination is supported with serial interfaces with HDLC or PPP encapsulation.
