Creating a Maintenance Domain
Connectivity fault management (CFM) divides a network into hierarchical maintenance domains, as
shown in Maintenance Domains.
1. Create maintenance domain.
ETHERNET CFM mode
domain name md-level number
The range is from 0 to 7.
2. Display maintenance domain information.
EXEC Privilege mode
show ethernet cfm domain [name | brief]
Example of Viewing Configured Maintenance Domains
Dell# show ethernet cfm domain
Domain Name: customer
Level: 7
Total Service: 1
Services
MA-Name VLAN CC-Int X-CHK Status
My_MA 200 10s enabled
Domain Name: praveen
Level: 6
Total Service: 1
Services
MA-Name VLAN CC-Int X-CHK Status
Your_MA 100 10s enabled
Creating a Maintenance Association
A Maintenance association (MA) is a subdivision of an MD that contains all managed entities
corresponding to a single end-to-end service, typically a virtual area network (VLAN).
• Create maintenance association.
ECFM DOMAIN mode
service name vlan vlan-id
Create Maintenance Points
Domains are comprised of logical entities called maintenance points. A maintenance point is a interface
demarcation that confines CFM frames to a domain.
There are two types of maintenance points:
• Maintenance End Points (MEPs) — a logical entity that marks the end-point of a domain.
• Maintenance Intermediate Points (MIPs) — a logical entity configured at a port of a switch that
constitutes intermediate points of an Maintenance Entity (ME). An ME is a point-to-point relationship
between two MEPs within a single domain.
