for instance server one has the address of 184.108.40.206 while server 2 has the address 220.127.116.11 ,so the cluster address will be 18.104.22.168,now i can ping 22.214.171.124 and 126.96.36.199, while unable tp ping the cluster IP 188.8.131.52,i think because of the ARP,so to resolve this issue i need to add ARP entry in the core switch where the servers are connected,so the question is how to find the MAC address of the cluster which is 184.108.40.206 to added as the below format
You're going to have to look at the cluster admin/config to find the virtual IP address of the cluster. Essentially, the Virtual IP address should have it's own virtual MAC address (with a short time out), and should register it with the switch gear in order to resolve properly.
Once a failure occurers, the secondary machine should update the MAC entry on the virtual IP address to the MAC address of the new server....
That's the theory behind it, it's just a matter of finding where (inside your cluster admin/config) the virtual IP is setup, which should give you information about it and the associated MAC address.

interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
