Our core switch is cisco 4506e switch, and recently we got one huawei s5700 which uplink to our cisco 4506. We want to enable lacp between them.The lacp is a standard protocol, so there is no problem even if they are different vendors. But there is one problem, my s5700 and 4506e all just leave one 10GE port. So I just wonder if 10GE and 1GE can form one lacp group? If I can not, what should I do to use these two ports(10GE and 1GE)?
