MCLAG KEEPALIVE

Hi Guys

I have deployed two DELL S5248F switches in MCLAG running   4.1.0-Enterprise_Standard. I have a problem with the "session status " been DOWN. Am using the management interface IP address for the "KEEPALIVE PEER LINK". I can ping the switch peer from each other and the peer link ports are UP. One thing I noticed is that the mclag domain do not have the option to specify "session-vrf ".  I have done the following; reapply the mclag domain configuration and also shut and no shut the peer link connecting the switches but to no avail.

SWITCH-A

Role                 : active
Session Status       : down
Peer Link Status     : up
