The MA Level for a particular Maintenance Domain. In order to allow administrations to configure different Maintenance Domains in the same Bridge without having to resort to detailed inter-organizational agreements as to which MA Levels are available for use, an administrator of a Maintenance Domain is expected to decide which of three roles that Maintenance Domain will play: the 'Customer' role, the 'Service Provider' role, or the 'Operator' role. The administrator is free to assign an MA Level to a Maintenance Domain within the range defined in the CfmMaLevels textual convention according to the Maintenance Domain's role. If two administrations ae operating Maintenance Domains using the same role in one Bridge,then they must agree to the MA Level each will use.
