The default maid format is short.
Global configuration mode
The no form of this command reverts back the maid format to short.
You cannot change the MAID format after a MEP is configured under an MA. You must first delete the MEP and then change the MAID format.
The following example sets the MAID format to long.
device# configure terminal device(config)# protocol cfm device(config-cfm)# domain name md1 level 4 device(config-cfm-md-md1)# ma-name ma1 id 30 vlan-id 30 priority 7 device(config-cfm-md-md1)# maid-format long
