Configure more than one port into mrouter port

I tried to configure 8 physical or 4 port-channels as mrouter port unsuccessful with OS10. And no Dell documentation show configuration example. The only one i found is below but without multiple ports to mrouter port. Need help.

I need to put 8 physical ports/4 port-channels into mrotuer ports in OS10. I tried various command variation and can only put either one physical or port-channel as mrouter port under a vlan interface.

No documentation shown how to put more interfaces as mrouter port in a single VLAN.

Need help?

MorgoW,

Based on my research I don't believe you can have multiples, and are only able to have one port. 

Let me know if this clarifies things.
