Do I need a live internet/DNS environment to test this switch? I have bridged vlan2 to e1. my VIP is set to X.X.X.47 and I have to services set to X.X.X.45 and .46. They both say active. The e1 port is up but my vlan2 is down. I am assuming that the circuit is my problem.
When you define a vlan IP address, the manual says that this is the IP address that the CSS will recieve traffic from, so that would be the virtual IP .47 that links to either .45 or .46 right?
I am suppose to configure 1 web server ip per port on the CSS switch? I currently connect the 2 web servers to a 8 port 10/100 switch and I have a straight ethernet cable from that 10/100 switch to port 1 (e1) on the css Switch.
Are all my port numbers suppose to be configured to 80 since they are being used for HTTP? Am I to use the HTTP keepalive function as well?
I guess any additional info would be great. I guess this isn't a click, click, and go switch like someone said.

the circuit ip address is the address of the device used for management - ie probes, telnet, ...
The virtual ip is configured under a content rule where you link the real servers with the command 'add service'.
Why don't you start by reading sample configs on our website :
Basic CSS Load Balancing Configuration
It could be useful to get you started.
Regarding your other questions concerning probe types, there is no *best* answer.
It is really dependent on your network and what you want to achieve.

Ok. Thanks for the tip on the examples. I have tried to follow them as much as possible and have made progress, but I am still having problems with a few things that i can;t seem to find answers for.
CSS 11501 = IP 10.0.0.49 Subnet 255.255.255.0 Gateway 10.0.0.1
Srv01 = IP 10.1.0.45 Subnet 255.255.255.0 Gateway NONE
Srv02 = IP 10.1.0.46 Subnet 255.255.255.0 Gateway NONE
Dell 2708 = IP 10.0.0.13 subnet 255.255.255.0 Gateway 10.0.0.1
Client = IP 10.0.0.113 subnet 255.255.255.0 Gateway 10.0.0.1
I have Srv01 and Srv02 plugged into the CSS 11501 with IP address listed above. They reside in e7 and e8.
I have a cable from e1 to the dell 2708.
I have a laptop with a cable to the dell 2708.
I have configured a vlan (VLAN10) which includes ports e7 and e8 with an IP interface of 10.1.0.1. Status is active (GREEN)
I have configured two services with Srv01 and Srv02 and the status of both are active (Green)
I have created a content rule which includes both srv01 and srv02 with a VIP of 10.1.0.25. Status is active (green)
So I go to one of the web servers that is plugged into e7 or e8 and I can ping 10.1.0.25 sucessfully on both boxes. But I can only ping each servers IP address on its own box. In otherwords I can't ping cross server. When I try to access 10.1.0.25 from the servers the page doesn't come up. I know the VIP works because I can ping it.
I have also configured a VLAN (VLAN5) for e1 which goes to the dell 2708 with an IP of 10.0.0.48. But the status is down.
I am doing something wrong and can't seem to figure it out. any suggestions? I can diagram a picture in visio if you need a visual aid. I might consider Cisco University after all this.

put your e1 interface in the same vlan as e7 and e8 if you want to use the same subnet 10.0.0.0/24.
Check the status of the physical link with 'show phy'. See if e1 is up.
If not, you may have to adjust the speed manually under the interface e1 config with the command 'phy ....' check available options.
I'm not sure why you have a 10.1.0.x subnet.
If you want this subnet to be the client side, you need your laptop to have a 10.1.0.x ip address as well.

When I moved to a different subnet everything became active pretty quick, but doesn't mean its right.

What is IP interface? What does it represent? If I put e7, e8, and e1 in the same vlan, does the IP interface represent the same IP for all ports?
So I can have everything on the 10.0.0.x subnet?
What if my web servers are on a different subnet? Isn't the the reason for the VIP so I can access them from any subnet?
It seems to me like I can't just get the concept and logic of this solution right. I have always used windows to load balance, never hardware.
