CFM Example

As shown in CFM Configuration Example, this example assumes a simple network and assumes that CFM is configured on the access switches, as well as the necessary VMANs configured with the ports added. This example shows a VMAN associated with two maintenance domains and two different MAs. UP MEPs are configured for an MA with MD level 6 and DOWN MEPs are configured for an MA with MD level 3.

Configure switch 1 for this example.

create cfm domain string cust-xyz-d6 md-level 6
configure cfm domain cust-xyz-d6 add association string cust-xyz-d6-m100 vman m100
configure cfm domain cust-xyz-d6 association cust-xyz-d6-m100 port 1:1 add end-point up 10
configure cfm domain cust-xyz-d6 association cust-xyz-d6-m100 port 2:1 add intermediate-point
create cfm domain string core-d3 md-level 3
configure cfm domain core-d3 add association string core-d3-m100 vman m100
configure cfm domain core-d3 association core-d3-m100 port 2:1 add end-point down 10

Configure switch 2 for this example.

create cfm domain string core-d3 md-level 3
configure cfm domain core-d3 add association string core-d3-m100 vman m100
configure cfm domain core-d3 association core-d3-m100 port 2:1 add intermediate-point
configure cfm domain core-d3 association core-d3-m100 port 2:2 add intermediate-point

Configure switch 3 for this example.

create cfm domain string cust-xyz-d6 md-level 6
configure cfm domain cust-xyz-d6 add association string cust-xyz-d6-m100 vman m100
configure cfm domain cust-xyz-d6 association cust-xyz-d6-m100 port 1:1 add end-point up 20
configure cfm domain cust-xyz-d6 association cust-xyz-d6-m100 port 2:1 add intermediate-point
create cfm domain string core-d3 md-level 3
configure cfm domain core-d3 add association string core-d3-m100 vman m100
configure cfm domain core-d3 association core-d3-m100 port 2:1 add end-point down 20

To display the group database, use the following command:
```
show cfm groups
```
