Topology: 

DGS-1510-28X (p25) --- (p27) DGS-3420-28SC
(P26) --- (p28)

In this document we will make the LACP configuration between DGS-1510 and DGS-3420 using the ports of 10G, for this we will use the ports # 27 and # 28 of the DGS-3420 and ports # 25 and # 26 the DGS-1510.


Step 1 - LACP configuration in the DGS-3420-28SC
