Field

Description

Multi-active recovery state

Whether the IRF fabric is in Recovery state:

  • Yes—The IRF fabric is in Recovery state. When MAD detects that an IRF fabric has split into multiple IRF fabrics, it allows one fabric to forward traffic. All the other IRF fabrics are set to the Recovery state. In Recovery state, MAD shuts down all service interfaces in the fabric except for the IRF physical interfaces and the service interfaces configured to not shut down.

  • No—The IRF fabric is not in Recovery state. It is active and can forward traffic.

Excluded ports(user-configured)

Service interfaces manually configured to not shut down when the IRF fabric transitions to the Recovery state.

Excluded ports(system-configured)

Service interfaces set to not shut down by default when the IRF fabric transitions to the Recovery state. These service interfaces are not user configurable.

MAD status

MAD operating status:

  • Normal—The MAD mechanism is operating correctly.

  • Faulty—The MAD mechanism is not operating correctly on the interface or port. Check the interface or port for connectivity or configuration problems.

  • N/A—MAD link status cannot be detected. This field might display N/A if BFD MAD is enabled on a management Ethernet port.

Member ID

IRF member ID of the local device.

Port

Member ports of the aggregate interface used for LACP MAD.

Neighbor

IRF member ID of the neighbor member device.
