Feature Description

Cisco IOS XE 17.13.1

Out-of-order Packet Counter on the Cisco RSP3 Module

You can configure Out-of-order packet counter for FPGA-based SAT on the Cisco RSP3 module.

Cisco IOS XE Dublin 17.10.1

SADT over VC when Access Interface is Down

You can perform Service Activation and Deactivation (SADT) over Virtual Circuit (VC) even when access interface is down.

Cisco IOS XE Bengaluru 17.5.1

TWAMP Light

This feature enables you to configure a TWAMP Light session using the ip sla responder twamp-light test-session command on the Cisco RSP2 module.

Cisco IOS XE Bengaluru 17.4.1

Configurable User-Defined and EMIX Packet Size

This feature allows you to configure user-defined and Enterprise traffic (EMIX) packet sizes. Use the following commands to configure user-defined and EMIX packet sizes:

  • packet-size user-defined packet size

  • packet-size emix-sequence emix-sequence [u-value u-value value]

SAT based support for configurable EMIX traffic pattern in FPGA

The support for EMIX packet size is enhanced. For EMIX traffic, packet sizes of 64, 128, 256, 512, 1024, 1280, 1518, Maximum Transmission Unit (MTU) and user-defined patterns are supported. These packet sizes are forwarded in ratio of 1:1:1:1:1.

Cisco IOS XE Amsterdam 17.3.1

Configurable Y.1564 Service Activation Frame Sizes and EMIX Support

Enterprise traffic (EMIX) packet size (default abceg pattern) is supported on both, Cisco ASR 900 RSP2 and RSP3 modules. For EMIX traffic, ITU-T Rec. Y.1564 packet sizes of 64, 128, 256, 1024, and 1518 bytes are supported. On the Cisco RSP3 module, it is supported in FPGA-based SADT.
