MDA Commands
mda
Syntax mda mda-slot
no mda mda-slot
Context config>card
Description This mandatory command enables access to a card's MDA CLI context to configure MDAs.
Default
No MDA slots are configured by default.
Parameters
mda-slot — The MDA slot number to be configured. Slots are numbered 1 and 2. On vertically oriented
slots, the top MDA slot is number 1, and the bottom MDA slot is number 2. On horizontally oriented
slots, the left MDA is number 1, and the right MDA slot is number 2. For 7750 SR-c12/4 systems,
MDAs may not be provisioned before MCMs are configured for the same slot. MCMs are not required
for CMA provisioning.

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 associations.
CMAs do not rely on MCM configuration and are provisioned without MCMs.
Note: CMAs are provisioned using MDA commands. A medium severity alarm is generated if an MDA/
CMA is inserted that does not match the MDA/CMA type configured for the slot. This alarm is cleared
when the correct MDA/CMA is inserted or the configuration is modified. A high severity alarm is raised
when an administratively enabled MDA/CMA is removed from the chassis. This alarm is cleared if the
