EX4600 RDMA over Converged Ethernet (RoCE) support?

Hi,

does anybody know if RDMA over Converged Ethernet (RoCE) is supported on EX4600?

Based on this:

https://www.juniper.net/documentation/en_US/junos/topics/concept/fibre-channel-cee-features-understanding.html

I would say yes, but since I can not find anything written specifically about RoCE & EX4600, I would like to know from knowledgable experts here?

Thank you in advance ...
