Hi, I have 2 SG300-28P without a router used for back-end network usage. The switches are configured in L2. I would like to configure on both switches: The default VLAN with Id 90 One VLAN with Id 80 to access the databases One VLAN with Id 70 to access the backup server One agregate with ports 25/26/27/28 Ports 1 to 8, 13 to 20 with VLAN 80 (90UP/80T) Ports 9 to 12, 21 to 24 with VLAN 70 (70UP) Computers connecting in VLAN 70 will only talk to VLAN 70. I would like to use the access mode for ports in VLAN 70. Computers connecting in VLAN 80 will only talk to VLAN 80. It seems that the servers on VLAN 80 on switch 1 can communicate with servers on VLAN 80 on switch 2. My problem is that the servers on VLAN 70 on switch 1 don't access the servers on VLAN 70 on switch 2. I suppose that this is due to the LAG 25/26/27/28 configured 90UP. Any idea to resolve this problem?
