Hi all,
Well I am trying to configure ip slb feature on my 6500 series Switch. I have done following configuration on my switch.
ip slb serverfarm TEST
real 172.16.1.215
inservice
!
real 172.16.1.237
inservice
!
ip slb vserver VERIFY_TEST
virtual 172.16.10.150 tcp 0
serverfarm TEST
sticky 60
inservice
exit
int Vlan10
ip add 172.16.10.252 255.255.255.0
exit
My servers are in vlan 1 and my clients are vlan 10. I am having 2 servers, on which I have configured 1.235 and 1.237. both the ports are in vlan 1, and virtual ip is of vlan 10.
I want to use Server Load balancing feature for http and other features.
Please help me on this.
Thanking you.
regards,
Mangesh.

Hi Giuseppe,
I have followed the same document but it's not working. The request reaching till my Switch after that nothing happening.
On real servers it shows me the status goes from failed to testing and then ready for test states. And then fall back to Failed.
6506_SW2#sh ip slb conn
vserver prot client real state nat
-------------------------------------------------------------------------------
VERIFY_TEST TCP 172.16.10.72:1646 172.16.1.215 SYNCLIENT none
6506_SW2#sh ip slb conn
vserver prot client real state nat
-------------------------------------------------------------------------------
And then it goes to Closing state. Can you please help me with Server end configuration also.
And also if there is any correctin required in my Switch configuration.
Thanks and Regards,
MAngesh.

What are you trying to load-balance. Is it http ?
Whatever it is can you from a client connect to the real address (NOT the VIP) and see if that works. If that does work then we can concentrate on the SLB side, if it doesn't it could be something wrong with your servers.

What are you load-balancing - sounds like http. You have to try accessing real servers on whatever port you are trying to load-balance on so if it is http then you need to try and connect using http - ping and telnet don't really tell us anything.

Hello Mangesh,
try to telnet to tcp port 80 to verify HTTP service is running on real servers
from a PC shell
telnet ipaddress port#
Hope to help

Agreed this is a useful premliminary test but Mangesh needs to actually try and bring a page up based on the real IP address unless of course he telnets and then uses the correct http get request syntax :-)
