I have a network layout like this (ESXi hosts):
Internal Network
+
+-----------------+ |
| Host1 | |
NLB Heartbeat |-----------------| |
+------------+<- 10.10.1.x | |
| | | | +------------+
| | 192.168.9.x ->+------------+ | |
| +-----------------+ | | |
|VLAN 2 | | Public |
| +-----------------+ |
| +-----------------+ | | |
| | Host2 | | +------------+
| |-----------------| |Cluster IP:
+------------+<- 10.10.1.x | |192.168.9.x
| | |
| 192.168.9.x ->+----------+
+-----------------+
My goal is to have the cluster IP accessible from inside the network. That is, I can access services on that IP address. The reason I'm using a VLAN is because of multicast flooding switch ports otherwise, so I want to isolate the NLB traffic to its own network.
Both hosts are connected to the same switch. For some strange reason, on my switch (HP 1910-48G), I am unable to add a static ARP entry for the cluster:
[3Com Baseline Switch]arp static 192.168.9.x 0100-5e7f-090a
MAC Address Error: Invalid MAC address.
The MAC address is formatted weird, but that's how the switch expects it.
So currently, I'm unable to ping or access anything on the cluster IP. All the VLAN traffic appears to be okay (the VMs can communicate with each other). Is there something I am missing?
