Creating the Maintenance Domain

A maintenance domain comprises network entities such as operators, providers, and
customers. To enable connectivity fault management (CFM) on an Ethernet interface,
you must create a maintenance domains, maintenance associations, and MEPs.
To create a maintenance domain:
Specify a name for the maintenance domain:
1.
[edit protocols oam ethernet connectivity-fault-management]
user@switch# set maintenance-domain domain-name
Specify a format for the maintenance domain name. If you specify
2.
configured:
A plain ASCII character string
A domain name service (DNS) format
A media access control (MAC) address plus a two-octet identifier in the range 0
through 65,535
none
[edit protocols oam ethernet connectivity-fault-management
maintenance-domain domain-name]
user@switch# set name-format format
For example, to specify the name format as MAC address plus a two-octet identifier:
[edit protocols oam ethernet connectivity-fault-management
maintenance-domain domain-name]
user@switch# set name-format mac+2oct
Configure the maintenance domain level, which is used to indicate the nesting

relationship between this domain and other domains. Use a value from 0 through 7:
[edit protocols oam ethernet connectivity-fault-management
maintenance-domain domain-name]
user@switch# set level level

Configuring the Maintenance Domain MIP Half Function

MIP Half Function (MHF) divides the maintenance association intermediate point (MIP)
functionality into two unidirectional segments, improves visibility with minimal
configuration, and improves network coverage by increasing the number of points that
can be monitored. MHF extends monitoring capability by responding to loop-back and
link-trace messages to help isolate faults. Whenever a MIP is configured, the MIP half
function value for all maintenance domains and maintenance associations must be the
same.
To configure the MIP half function:
[edit protocols oam ethernet connectivity-fault-management maintenance-domain
domain-name]
user@switch# set mip-half-function (none | default | explicit)
