I have a very restricted situation where I need two physical servers to be presented on the network as one virtual IP address.
I cannot make any changes to the servers, i.e. Cluster or NLB so that option is out.
I was looking at the SLB option but this isn't supported on 4500's. I also do not have the option of additional blades or equipment so just the command syntax of the switch is my option.
Essentially I'm looking at a command syntax on a 4500 to translate requests to a specific IP and present them to the servers behind.
The physical IP's are:
SERVER 1 - 192.168.0.10
SERVER 2 - 192.168.0.11
I would like to use 192.168.0.1 all the time and have the network translate the request to either of the two physical IP's of the servers. I don't want any additional functionality of load balancing, just a translation to one server and if that isn't a available then the request goes to the second.
I'm wondering if NAT can translate to one IP and if this isn't available then the 2nd.
I hope this makes some sense. Any help is appreciated.
