Activating Server Load Balancing Services

When you activate a real server, the server is again eligible for new virtual 

server connections, and the LocalDirector sends to the server the next 

qualifying connection. 

When you suspend a virtual server, they are set to out of service.

When you suspend a real server, you have four options:

  Sticky The LocalDirector does not assign new connections to it, but 

lets old connections continue to run until they have been completed. An 

out of service real server can still be accessed by clients entering its 

actual IP address.

  Out of Service The LocalDirector does not assign new connections to 

it, and the connections are cleared when it is put back in service.

  Maintenance The LocalDirector does not assign new connections to it, 

and the connections are not cleared when it is put back in service.

  Failed The server is failed by an external source (for example, another 

device notifies the LocalDirector that an application is down.)

CSM 3.x or later versions.

When you activate a real server, the server is again eligible for new virtual 

server connections, and IOS SLB or Content Switching Module sends the

suspend a virtual server it will be out of service.

When you activate a virtual server, it enables a virtual server for use by the 

IOS SLB or Content Switching Module. 

When you suspend a virtual server, it disables a virtual server for use by the 

IOS SLB or Content Switching Module.
