Server Load Balance in one network using CSM Cat6509

[budiman]

I have 2 Web Servers with real IP address 10.1.12.61 and 10.1.12.62 (subnet mask 255.255.255.0). The virtual IP address configured on CSM is 10.1.12.100

I also have 2 Application Servers with real IP address 10.1.12.81 and 10.1.12.82 (subnet mask 255.255.255.0). The virtual IP address is 10.1.12.120.

Users will access Web server using the virtual IP address (10.1.12.100) so that the traffic will be load balanced.

But there is also requirement that those Web Servers access Application Servers using IP address 10.1.12.120 so that the traffic will be load balanced as well.

Is this requirement feasible?

Can CSM load balance between servers in one network address?

That should work depending on the application servers compatibility. I would have your Cisco designer/sales office look it over to be sure.

Budiman,

I am building the same situatiuon here. But the most simple part seems not to be working. I have two webservers in the same subnet as my VIP.

The clients can be everywhere in every subnet.

This is what happens:

btpebgw70#sh mod contentSwitchingModule 9 conns

prot vlan source destination state

----------------------------------------------------------------------

In TCP 401 192.6.53.42:1901 151.183.58.196:80 ESTAB

Out TCP 401 151.183.58.196:80 192.6.53.42:1901 ESTAB

ok this is good but:

btpebgw70#sh mod contentSwitchingModule 9 reals detail

151.183.58.201, ORBIS, state = OPERATIONAL

conns = 0, maxconns = 4294967295, minconns = 0

weight = 8, weight(admin) = 8, metric = 0, remainder = 0

total conns established = 58, total conn failures = 58

the failures have the same value as the established. Can you send me your config part of the csm because I am getting tired of this. Please email to dennis@attorn.nl

Thanks in advance!
