Default MDC and non-default MDCs

A device supporting MDCs is an MDC itself, and it is called the "default MDC" (for example, Device
in Figure 24). The default MDC always uses the name Admin and the ID 1. You cannot delete it or change
its name or ID.
When you log in to the physical device, you are logged in to the default MDC. Configuring the physical
device is the same as configuring the default MDC.
From the default MDC, you can manage the entire physical device, create and delete non-default MDCs
(for example, Device A, Device B, and Device C in
storage space (Flash and CF card), and memory space to non-default MDCs.
No MDCs can be created on a non-default MDC. Administrators of non-default MDCs can only manage
and maintain their respective MDCs.
A non-default MDC can use only the resources assigned to it. It cannot use the resources assigned to
other MDCs or the remaining resources on the physical device. Resources that are not assigned to any
non-default MDC belong to the default MDC.

MDC configuration guidelines

When you configure MDCs, follow these guidelines:
To configure both IRF and MDCs on a device, configure IRF first. Otherwise, the device will reboot
•
and load the master's configuration rather than its own when it joins an IRF fabric as a subordinate
member, and none of its settings except for the IRF port settings take effect.
Before assigning a physical IRF port to an MDC or reclaiming a physical IRF port from an MDC, you
•
must use the undo port group interface command to restore the default. After assigning or
reclaiming a physical IRF port, you must use the save command to save the running configuration.
For more information about the undo port group interface command, see Virtual Technologies
Command Reference.
