Good day! Just need an assistance with regards to Cluster IP.
We have two Web Servers and configured as Network Load Balancing in a cluster for failover.
WEB1 IP: 192.168.1.50
WEB2 IP: 192.168.1.51
Both configured with Cluster IP: 192.168.1.100 on Multicast mode.
TEST ON LAB USING ORDINARY 10/100 UNMANAGED SWITCH
I can ping all the IP addresses on the LAN and when I http://192.168.1.110 on any PC
on the LAN works no problem.
TEST ON PRODUCTION USING CISCO SG200 50/50 PORT SWITCH
I can ping all the IP addresse on the LAN and when I http://192.168.1.110 on a different
machine i did not work, but on the server itself will work as expected.
NOTE: Both tests are on LAN only.
I wonder if this is something to do with the switch because of Cluster IP MAC address.
Do I need to configure something on the switch? can you give advise please. Many Thanks.
You might have to setup a lag between the switch and those two ports on that server.
Chances are spanning tree is blocking the higher port number and not allowing response on that port.
