thanks for this information that I had missed
most of documents related to VCP Uplink ports refer "optical ports" for these ports.
other associated questions related to the fact that you can aggregate 2 or more VCP ports into a LAG :
see this link that explains about that :
If I understand correctly this page, this LAG would be established between members of a unique VC to increase thruput inside the VC and to increase the resiliency inside the VC
Questions :
1) is it possible to create a VCP based LAG of 2*10G links between 2 members of a unique VC with 2 different link types :
a) 1 link based on SFP+ 10G optical ports of the expansion module
b) and 1 link based on RJ45 10G copper built-in ports of the 32ports EX4550 base module
or do both links inside the VCP based LAG have to be of the same type ?
on the drawing below, see for example the "vertical" VCP based LAG between member 00 and member 01 on the left side
2) is it possible to have a VCP based LAG between 2 pairs of EX4550 in the same VC ?
see drawing below for the "horizontal" LAG (based on 2 SFP+ 10G Fiber links between the 2 DCs) that joints the members 00 & 01 pair on the left to the members 02 & 03 pair on the right ?
thanks in advance
