error ipv4 multicast entry

[Kar_Del_Moral]

I open a GTAC case, I just put in this x440 stack (today first day of production) and I got the ipv4 multicast entry error any suggestions?

And by the way... The Hub is the Best support group ever! 

Thanks all for your feedback...

I have also another group of x440 switches, they are not in stack, are daisy chain, but I don't see that error on them... they are running an oldest xos version, 15.2.1.5 the stack 15.7.1.4.. so the warning error is due to the stack configuration? on the daisy chain I haven't apply any mcast configuration and the cache shows 24 entries on the stack around 46

Thanks

Did the switch reboot and possibly without the configuration being saved? Assuming that is the case I would to refer to Stephane's post above and put it into L2 only, most likely based on your config as you have shared it most likely wont cause you any issue.
That command would be: "configure forwarding ipmc lookup-key mac-vlan"

A command that is useful to check the current HW settings of a given platform (including ipmc lookup-key) is:

show forwarding config

[Bill_Stritzinge]

I would make the change as suggested to "configure forwarding ipmc lookup-key mac-vlan" and let it roll...

Couple of other commands to see the mcast cache...

"show mcast cache summary"
or
"show mcast cache" (will show you all)
