I was wondering if anyone could help with a switch issue I'm experiencing.
My manager is currently setting up a bunch of servers at our datacentre. They are all Dell machines (2970s I believe) and connect to a Cisco Catalyst 2950 Layer 2 switch.
The problem he has is thus:
1 server hosts 2 IP addresses on a single NIC. The rest host only a single IP address. Pings from any of these servers to the default IP address on the "double IP" server are all successful. Pings to the secondary address all fail.
Now, as this is only a layer 2 switch, this would seem to make sense. I realse it doesn't have any concept of IPs and I assume that any ARP is done elsewhere. It there anything we can do to make this secondary IP address visible? Basically we want to know how to "assign" 2 IPs to a single MAC (without purchasing a layer 3 switch!)
Am I on the correct train of thought? :-)
Many thanks for any help,
