Hello,
We installed an sophos XGS116 and try to use the Lag configuration for connecting to the 2 switches Cisco SG200 50p.
The problem is that's not working. When i connect the first switch, all is alright but nothing on the second. But, when i connect only the second switch, it's working correctly but nothing on the first switch. Why ? Did we have a missconfiguration ?
Is there probably a problem with the default mgmt vlan on the cisco ? Because the cisco has the Vlan 1 as default but the vlan 200 as management vlan. That play a role ?
You will found in attachment the network topologie.
Any idea ?
Best regards
