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. MDAs may not be provisioned before MCMs
are configured for the same slot. MCMs are not required for CMA provisioning.
Values
7710 SR c-12 MDA: 1, 3, 5, 7, 9, 11
7710 SR c-12 CMA: 1-12

mda-type
Syntax mda-type mda-type
no mda-type
Context config>card>mda
Description
This mandatory command provisions a specific MDA/CMA type to the device configuration for the
slot. The MDA/CMA can be preprovisioned but an MDA/CMA must be provisioned before ports can
be configured. Ports can be configured once the MDA/CMA is properly provisioned.
A maximum of two MDAs or four CMAs (or a combination) can be provisioned on a 7710 SR-c4.
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 either the correct MDA/CMA type is inserted or the configuration is modified.
A low severity trap is issued if an MDA/CMA is removed that is administratively disabled.
An alarm is raised if partial or complete MDA/CMA failure is detected. The alarm is cleared when
the error condition ceases.
