You can specify the maintenance association short name format as a plain ASCII character string, the VLAN identifier of the VLAN you primarily associate with the maintenance association, a two-octet identifier in the range from 0 through 65,535, or a name in the format specified by RFC 2685. The default short name format is ASCII character string.
To configure the maintenance association short name format, include the short-name-format (character-string | vlan | 2octet | rfc-2685-vpn-id) statement at the [edit protocols oam ethernet connectivity-fault-management maintenance-domain domain-name maintenance-association ma-name] hierarchy level.
