Supported Software Features in Cisco IOS XE Gibraltar 16.11.x
Resilient Ethernet Protocol
The Resilient Ethernet Protocol (REP) is a Cisco proprietary protocol that provides an alternative to the Spanning Tree Protocol (STP). REP provides a way to control network loops, handle link failures, and improve convergence time. It controls a group of ports connected in a segment, ensures that the segment does not create any bridging loops, and responds to link failures within the segment. REP provides a basis for constructing complex networks and supports VLAN load balancing.

NCS 520 supports Y.1564, which is an Ethernet service activation or performance test methodology for turning up, installing and troubleshooting Ethernet-based services. This test methodology allows for complete validation of Ethernet service-level agreement's (SLAs) in a single test.
For more information, see IP SLAs Configuration Guide, Cisco IOS XE Gibraltar 16.11.x (Cisco NCS 520).
The IETF Two-Way Active Measurement Protocol (TWAMP) defines a standard for measuring round-trip network performance between any two devices that support the TWAMP protocols. The TWAMP-Control protocol is used to set up performance measurement sessions. The TWAMP-Test protocol is used to send and receive performance-measurement probes.
