What is y 1731 standard?

What is y 1731 standard?

1731 is an international standard that defines Operations, Administration and Maintenance (OAM) functions and mechanisms for Ethernet-based networks.

What is Cisco cfm?

IEEE Connectivity Fault Management (CFM) is an end-to-end per-service Ethernet layer Operations, Administration, and Maintenance (OAM) protocol. This document describes the implementation of IEEE 802.1ag Standard-Compliant CFM (IEEE CFM) in Cisco IOS XE software.

What is cfm in networking?

Connectivity Fault Management (CFM) Feature Overview and Configuration Guide. Connectivity Fault Management (CFM) is an IEEE 802.1ag and ITU Y. 1731 standard for managing connectivity at the Ethernet service level. The 802.1ag standard adds Fault management capabilities to Ethernet, while the ITU Y.

What is Ethernet OAM protocol?

Ethernet Operations, Administration, and Maintenance (OAM) is a protocol for installing, monitoring, and troubleshooting Ethernet networks to increase management capability within the context of the overall Ethernet infrastructure.

Which CFM message type is used for an L2 ping?

MIPs are used for L2 ping and trace-route (which will be explained below).

What is up MEP and down MEP?

Up MEP is created on UNI where as Down MEP is created on NNI. Up Mep packets will follow service path and be transmitted out. Down Mep packets will be transmitted directly since it is created on NNI.

What is Ethernet OAM Cisco?

Ethernet CFM is an end-to-end per VLAN Ethernet layer OAM protocol that includes proactive connectivity monitoring, fault verification, and fault isolation. Ethernet CFM, as specified by IEEE 802.1ag, is the standard for Layer 2 ping, Layer 2 traceroute, and end-to-end connectivity check of the Ethernet network.

What is OAM testing?

OAM is a set of functions that provides system or network fault indication, performance monitoring, security management, diagnostic functions, configuration and user provisioning. The purpose of these management tools or capabilities is to enable the monitoring and quick restoration of a network in case of failure.

What is OAM 802.3 Ah Ethernet?

Ethernet OAM is one part of the capability needed to meet these SLAs. WHAT IS ETHERNET OAM? OAM is a set of functions that provides system or network fault indication, performance monitoring, security management, diagnostic functions, configuration and user provisioning.

What is SPBM extreme?

Extreme Networks Extreme Automated Campus solutions provide the ability to simultaneously use multiple transmission paths and quickly recover in the event of an accident. A network consisting of multiple physical switches is one distributed network.

What is ITU-T Y.1731 in a service provider?

ITU-T Y.1731 performance monitoring provides standards-based Ethernet performance monitoring that encompasses the measurement of Ethernet frame delay, frame delay variation, and frame loss and throughput as outlined in the ITU-T Y-1731 specification and interpreted by the Metro Ethernet Forum (MEF).

Is the Y.1731 PM measurement SSO compliant?

Y.1731 PM measurement only works for a point to point network topology. Y.1731 PM is not SSO compliant. After switchover all sessions data is cleared. In case of one way session or two way session, when one way statistics are required, PTP needs to be synchronized between peers and stable.

How does Y.1731 performance monitoring help service providers?

Combined with IEEE-compliant CFM, Y.1731 performance monitoring provides a comprehensive fault management and performance monitoring solution for service providers. This comprehensive solution in turn lessens service providers’ operating expenses, improves their service-level agreements (SLAs), and simplifies their operations.

How does clock synchronization work on a Cisco 7600 Router?

Note On a Cisco 7600 router, clock synchronization is achieved using a 2-port gigabit synchronous ethernet SPA. On an ES+ line card, the Real Time Clock (RTC) is synchronized to the 2-port gigabit synchronous ethernet SPA time source using Precision Time Protocol (PTP) as the time source protocol.
