Configuring Connectivity Fault
Management
This chapter describes how to configure the IEEE 802.1ag (also known as
Dot1ag) protocol, which is available on the PowerConnect M6348 switch.
Dot1ag ( IEEE Standard for Local and Metropolitan Area Networks Virtual
Bridged Local Area Networks Amendment 5: Connectivity Fault
Management ) enables the detection and isolation of connectivity faults at
the service level for traffic that is bridged over a metropolitan Ethernet LAN.
The topics covered in this chapter include:
• Dot1ag Overview
• Default Dot1ag Values
• Configuring Dot1ag (Web)
• Configuring Dot1ag (CLI)
• Dot1ag Configuration Example
Dot1ag Overview
With the emergence of Ethernet as a Metropolitan and Wide-Area
Networking technology, different operators often work together to provide
end-to-end services to enterprise customers. This has driven the need of a
new set of OAM (Operations, Administration, and Maintenance) Protocols.
Service-Level Connectivity Fault Management (CFM) is the OAM protocol
provision for end-to-end service-layer instances in carrier networks. CFM
provides mechanisms to support the administrator in performing connectivity
checks, fault detection, fault verification and isolation, and fault notification
per service in the network domain of interest. Unlike Ethernet OAM (IEEE
802.3ah), where the faults are detected and notified on a single point-to-point
NOTE: The Connectivity Fault Management feature is not available on the
PowerConnect M6220, M8024, or M8024-k switches.
