Configuring Ethernet OAM
This section describes how to use Alcatel-Lucent’s Command Line Interface (CLI) commands to config-
ure Ethernet Service OAM on a switch. Consider the following guidelines when configuring Service
OAM maintenance entities:
•
Ethernet OAM is not supported on mobile, mirrored, or aggregate ports (the physical port members of
an aggregate).
•
Ethernet OAM is also not supported on dynamically learned VLANs.
•
Implementing Ethernet OAM is supported on any full-duplex point-to-point or emulated point-to-point
Ethernet link. It need not be implemented system wide.
•
Management systems are important for configuring Ethernet OAM across the network. They also help
to automate network monitoring and troubleshooting. Ethernet OAM can be configured in two phases:
network configuration phase and service activation phase.
•
The network configuration phase enables Connectivity Fault Management (CFM) on the switches. This
is also the phase where Maintenance Intermediate Points (MIP) and Maintenance End Points (MEP)
are identified and set up.
•
Any port on a switch is referred to as a Maintenance Point (MP). An MP can be either a MEP or MIP.
A MEP resides at the edge of a Maintenance Domain (MD), while a MIP is located within a MD.
•
In the Service Activation phase, a new end point is created on a VLAN as a MEP. This enables the
configuration of continuity-check and cross-check functionality.
Configuring a Maintenance Domain
To create a Maintenance Domain (MD), use the ethoam domain command, by entering ethoam domain ,
followed by the domain name, the keyword format, the domain name format type, the keyword level , and
the level of the domain. For example:
-> ethoam domain esd.alcatel-lucent.com format dnsName level 5
Here, the MD esd.alcatel.com is created.
Note that the level must be 0-2 at operator level, 3-5 at provider level, and 6-7 at customer level when
creating the level of domain.
To remove an MD, use the no form of this command. For example:
-> no ethoam domain esd.alcatel-lucent.com
Note that with this implementation of Ethernet OAM, it is only possible to delete an MD when there is no
Maintenance Association, End Point, or Intermediate Point associated with the MD.
