Creating and Associating MAs

Within a given domain, you can associate maintenance associations (MAs). Extreme Networks‘ implementation of CFM associates MAs with service instances. All of the ports in that service instance are now in that MA and its associated domain.

Each MA associates with one service instance, and each service instance may associate with more than one MA; you can configure more than one MAs in any one domain.

Like the domains, ExtremeXOS supports multiple formats for naming the MA. The following formats are supported for naming the MAs:

Character string
2-octet integer
RFC 2685 VPN
VLAN (Virtual LAN) ID
Y.1731 MEG name

To add an MA to a domain using the character string format, use the following command:

configure cfm domain domain_name add association string name [vlan vlan_name|vman vman_name]
To add an MA to a domain using the 2-octet integer format, use the following command:

configure cfm domain domain_name add association integer int [vlan vlan_name|vman vman_name]
To add an MA to a domain using the RFC 2685 VPN ID format, use the following command:

configure cfm domain domain_name add association vpn-id oui oui index index [vlan vlan_name|vman vman_name]
To add an MA to a domain using the VLAN ID format, use the following command:

configure cfm domain domain_name add association vlan-id vlanid [vlan vlan_name|vman vman_name]
To add an MA using Y.1731 compliant MEG, use the following command: configure cfm domain domain_name add association meg [meg name] [vlan vlan_name|vman vman_name]
To delete an MA from a domain, use the following command:

configure cfm domain domain_name delete association association_name

In addition to supporting multicast destination MAC address for CCM and LTM frames specified by the 802.1ag standard, ExtremeXOS CFM supports the use of a unicast destination address for CCM and LTM frames.

This allows the support of a CFM operation in a network where use of multicast address is prohibited.
To configure the destination MAC address type for an MA, use the following command:

configure cfm domain domain-name association association_name destination-mac-type [unicast | multicast]
Use the following command to add a remote MEP to an MA statically:

configure cfm domain domain-name association association_name add remote-mep mepid { mac-address mac_address }

ExtremeXOS CFM supports configuring remote MEPs statically for CFM operation where dynamic discovery of MEPs in an MA using multicast address is prohibited.
To delete a remote MEP from an MA, use the following command:

configure cfm domain domain-name association association_name delete remote-mep mepid
To configure a remote MEP MAC address, use the following command:

configure cfm domain domain-name association association_name remote-mep mepid mac-address mac_address
