MCX from replicas

Hi, I'm required to prove that failover is working on WGM OD servers and need to prove which OD replica servers MCX settings are being retrieved from within our network. Is there a cmd or other to show this? As we have replicas in different sites I'm required to show that the clients are using the local OD replica servers. 10.5.5 Servers with 10.5.x clients, golden triangle config Many thanks
