Hi to everyone.
I have some HPE HPE 1920S JL381/JL384 SWITCH connected directly by a single Eth cable, and I want to test in my LAB some configuration for improve the performance, using LACP (TRunk).
There are about 10 vlan configurated, I want to aggregate 3/4 1Gbs port for connect , for example Switch 1 to Switch 2., and improve the bandwith of connection between the 2 switch.
I try both Static and Dynamic trunk mode, all With ALL existing VLAN included and TAGGED, but I see a high downgrade of speed performance,.. This is the scenario before and after TRUNK :
Before: Switch 1 connected with single Ethernet Cable to Switch 2
Trasfer n.1 4 GB file from PC in Switch1 to Switch 2 : About 80 MB/s
Trasfer n.2 4 GB file from PC in Switch1 to Switch 2 : never over 30 MB/s each trasfer??? Why this loss of speed??
After: Switch 1 connected with n.3 Ethernet Cable to Switch 2, TRUNK Dynamic mode (same in static mode)
Trasfer 4 GB single file from PC in Switch1 to Switch 2 : About 80 MB/s
Trasfer n.2 4 GB file from PC in Switch1 to Switch 2 : never over 30 MB/s each trasfer??? Why this loss of speed, and there aren't improve for the 3x1 Gb/s of connections?
I hope to obtain a real 3Gb/s channel connection using LACP..
Where are my errors???
Thanks a lot.
