Hello there,


I have the following setup:


INTERNET <--> CSS11501 <----> SERVER CLUSTER


Vlan address of server cluster is in the same subnet of that of the CSS. server's gateway is IP of CSS. My problem is when we do load testing on each server, it goes well with no errors. but when we do the load testing using the VIP address of the cluster, the load testing app gets a timeout when getting the flash content of the cluster.


my config on the content is:


content BGUIDE_NEW

vip address 192.168.8.4

protocol tcp

port 80

balance leastconn

advanced-balance sticky-srcip

add service SRV1

add service SRV2

add service SRV3

add service SRV4

active


Is there anything lacking in my content config that I need to do? Where else in the config do I need to look at.


Thanks in advanced.


JC

  • Cisco Employee,

is your testing tool in the same subnet as the servers ? If so, you need a group to do client nat.


Are all connections failing or just some of them ?


Get a sniffer trace and you should see where the problem is.

Testing tool is outside the subnet/network. Only the particular file cannot be loaded. I haven't used any sniffer programs yet. Should I install it on one of the server in the cluster? What do I look for on the trace.


Sorry about this. I haven't used sniffer programs yet.


Thanks
