I'm kinda new to networking and I'm trying to setup a server with redundancy to two switches, sorry if this is not the right place to ask.

This is my situation right now : https://imgur.com/a/I9QF4c9

I have 3 NICs on the Server teamed up as a single NIC, i've connected two of these NICs to Switch 1 and created a LAG on the switch.

Now I would like to connect the third NIC to Switch 2 so that if Switch 1 dies the server still has a connection to the network, but i'm not sure about what I need to do.

Could someone please point me in the right direction?

I should add that the switches are 2 Cisco SG200-26P

Thank you very much in advance

  • NIC 3 cannot be part of the aggregation group because it is connected to a different switch. Unfortunately, questions about host/server configurations are off-topic here. You could ask about that on Server Fault for a business network. – Ron Maupin Jan 14 at 14:39
  • You need switches that support multi-chassis LAG. I'm not sure the SG line does without configuring them as a cluster. – Ricky Jan 15 at 5:22
