Hi!

I am not able to find much example about MAD.

I am configuring IRF between two HPE 5900AF and will also configure MAD on them.

From a post I learn that mad bfd is good choice. 

I made the the below configuration via different sources.

Looks ok. Just made sure that vlan 80 is only used for MAD.

There is quite some documentation available for IRF. Try this link for networkinsupport.hpe.com portal.

HPE IRF Technolo9gy Whitepaper contains a lot of very useful information.

Setup and configuration task list from documentation.

To set up and configure an IRF fabric:

1. (Required.) Planning the IRF fabric setup 
2. (Required.) Assigning a member ID to each IRF member device
   Perform this task on each member device.
3. (Optional.) Specifying a priority for each member device
   Perform this task on one or multiple member devices to affect the master election result.
4. (Optional.) Installing expansion interface cards
   This task is beyond the scope of this document. For information about installing expansion interface cards, see the switch installation guide.
5. (Required.) Connecting IRF physical interfaces 
6. (Required.) Binding physical interfaces to IRF ports
   Perform this task on each member device. When you complete IRF port binding and activation on all IRF member devices, the IRF fabric is formed.
7. (Required.) Accessing the IRF fabric
   When you log in to the IRF fabric, you are placed at the master's CLI, where you complete subsequent IRF settings and configure other features for the member devices as if they were one device.
8. (Optional.) Configuring a member device description 
9. (Optional.) Configuring IRF link load sharing mode:
   1.  Configuring the global load sharing mode
   2.  Configuring a port-specific load sharing mode
10. (Optional.) Configuring IRF bridge MAC persistence 
11. (Optional.) Enabling software auto-update for software image synchronization
    As a best practice, enable software auto-update to ensure system software image synchronization.
12. (Optional.) Setting the IRF link down report delay
13. (Required.) Configuring MAD: 
    MAD mechanisms are independent of one another. As a best practice, configure multiple MAD mechanisms for an IRF fabric.
    1. Configuring LACP MAD
    2.  Configuring BFD MAD
    3.  Configuring ARP MAD
    4.  Configuring ND MAD
    5.  Excluding service interfaces from the shutdown action upon detection of multi-active collision
14. (Optional.) Maintaining an IRF fabric:
    1. Recovering an IRF fabric
    2. Removing an expansion interface card that has IRF physical interfaces
    3. Replacing an expansion interface card that has IRF physical interfaces

If the cable is supported, there should be no issues replacing it online.

Unsupported cables on IRF links can sometimes be a tricky business.
