I have two Cisco SG200 Switch A and B. I have two servers on Swtich A each connected via LACP LAG 2&3. LAG 2&3 are one Vlan 1000 which is set two access mode. Server 1&2 can ping each other. Switch A&B are connected via 2 uplinks Which are LACP LAG 1 is on the default Vlan the second Uplink LAG is set to access on both ends in Vlan 1000. Switch B has 1 server connected via LACP which is set to access on VLAN 1000 but server 3 can not ping 1&2. If I set everything to trunk and the Default Vlan I can ping what am I doing wrong. I want a backup network that is on VLAN 1000 that server 1&2 on Switch A are on and Server 3 on switch B is on . I dont want any other traffic on 1000. Now I have other VLAN's on each switch all ports on the VLAN's are set to access due to no cross communication the only VLAN that is on both switches is the default and VLAN 100 and the backup network VLAN 1000 but I can not get 1000 to work. Any ideas?
