How to create custom Service Group?

How to create these custom service group?can you create three different virtual servers (one is on udp/53, another is on tcp/5950 and the last one is on tcp/23000) instead?

 

 

Also do I need to add Health check on both Node and Pool level to work it successfully.it is not mandatory. either or both is okay.

 

 

How to create new custom Health check based UDP or TCP ports and individual scripts?by default, health monitor will check pool member's service port.

Hi Nitass,

 

 

Thanks for your reply.

 

 

I am still missing more info. For example I want to create a Virtual server which will listen on port TCP 23000. So when I am creating a Pool I could not select any "Service" which is only "TCP" otherwise I could select "TCP" and Port "23000".

 

 

This is the same situation with Virtual server the available Service for plain TCP/UDP is missing in the list.

 

 

How to create a custom TC/UDP based service which will be available in the service List while creating new Pool or VS?

 

 

These are very good questions. You can specify a protocol (SCTP, TCP or UDP) at the Virtual Server level which would certainly restrict the 'listener' to just that protocol but for the Pool Members, I've no idea.

The pool has no concept of protocol--it's just a collection of layer 4 IP:ports. As WLB said, the protocol for traffic is determined at the virtual server level.

 

 

See this SOL for more info:

Hi Aron,

 

 

Thanks for your reply.

 

 

My requirement is we need to create a Virtual server which will listen on TCP port 23000. It will have 3 nodes.

 

 

Can you tell me how to create this?

 

Haque, set the pool up as necessary, when creating the VS specify a Service Port of 23000 and a Protocol of TCP in the configuration section just after the State option.
