Description This mandatory command provisions a specific MDA type to the device configuration for the slot.
The MDA can be preprovisioned but an MDA must be provisioned before ports can be configured.
Ports can be configured once the MDA is properly provisioned.
A maximum of two MDAs can be provisioned on an IOM. Only one MDA can be provisioned per
IOM MDA slot. To modify an MDA slot, shut down all port associations.
A maximum of six MDAs or eight CMAs (or a combination) can be provisioned on a 7750 SR-c12.
Only one MDA/CMA can be provisioned per MDA slot. To modify an MDA slot, shut down all port
