To change an MDA or XMA type already provisioned for a specific slot or card, first you must shut down the slot/MDA/port configuration and then delete the MDA or the XMA from the configuration.
To modify or delete XMAs, use the MDA command structure.
Use the following CLI syntax to modify an MDA on the 7450 ESS and 7750 SR platforms (or an XMA on the 7950 XRS platforms):
config> port port-id
— shutdown
config> card slot-number
— shutdown
— [no] mda mda-number
— [no] mda-type mda-type
— shutdown
