Configuring Ethernet CFM Crosscheck

Complete the following steps to configure Ethernet CFM crosscheck:

 

Command

Purpose

Step 1

 

 

configure terminal

Enter global configuration mode.

Step 2

 

 

ethernet cfm mep crosscheck start-delay delay

Configure the number of seconds that the device waits for

 

 

remote MEPs to come up before the crosscheck is started.

 

 

The range is 1 to 65535; the default is 30 seconds.

Step 3

 

 

ethernet cfm domain domain-namelevel level-id

Define a CFM domain, set the domain level, and enter

 

 

ethernet-cfm configuration mode for the domain. The

 

 

maintenance level number range is 0 to 7.

Step 4

 

 

service {ma-name ma-number vpn-id vpn} {vlan

Define a customer service maintenance association name

 

vlan-id}

or number or VPN ID to be associated with the domain, and

 

 

a VLAN ID, and enter ethernet-cfm-service configuration

 

 

mode.

 

 

• ma-name—a string of no more than 100 characters that

 

 

identifies the MAID.

 

 

• ma-number—a value from 0 to 65535.

 

 

• vpn-idvpn—enter a VPN ID as the ma-name.

 

 

• vlan vlan-id—VLAN range is from 1 to 4094. You

 

 

cannot use the same VLAN ID for more than one

 

 

domain at the same level.

Step 5

 

 

mep mpid identifier

Define the MEP maintenance end point identifier in the

 

 

domain and service. The range is 1 to 8191

Step 6

 

 

end

Return to privileged EXEC mode.

Step 7

 

 

ethernet cfm mep crosscheck {enable disable}

Enable or disable CFM crosscheck for one or more VLANs

 

domain domain-name {vlan {vlan-id any} port}

or a port MEP in the domain.

 

 

• domain domain-name—Specify the name of the

 

 

created domain.

 

 

• vlan {vlan-id any}—Enter the service provider

 

 

VLAN ID or IDs as a VLAN-ID (1 to 4094), a range of

 

 

VLAN-IDs separated by a hyphen, or a series of

 

 

VLAN IDs separated by comma. Enter any for any

 

 

VLAN.

 

 

• port—Identify a port MEP.

Step 8

 

 

show ethernet cfm maintenance-points remote

Verify the configuration.

 

crosscheck

 

Step 9

 

 

show ethernet cfm errors [configuration]

Enter this command after you enable CFM crosscheck to

 

 

display the results of the crosscheck operation. Enter the

 

 

configuration keyword to display the configuration error
