Hi All,
I'm working to troubleshoot session establishment to the real servers. I have checked and found servers in the server farm with different port number. I'm wondering how servers in the server farm with different port numbers. Is this something wrong?
Below is the configuration:
serverfarm host SF-T1WBCT-WLS-T11516
predictor hash cookie ACE-COOKIE-T1WBCT-WLS-T11516
rserver RS-T1WBCT-WLS-10.102.161.173-T 11516
probe PR-T1WBCT-WLS-T11516
inservice
rserver RS-T1WBCT-WLS-10.102.161.173-T 11517
probe PR-T1WBCT-WLS-T11517
inservice
rserver RS-T1WBCT-WLS-10.102.161.173-T 11518
probe PR-T1WBCT-WLS-T11518
inservice
rserver RS-T1WBCT-WLS-10.102.161.174-T 11516
probe PR-T1WBCT-WLS-T11516
inservice
rserver RS-T1WBCT-WLS-10.102.161.174-T 11517
probe PR-T1WBCT-WLS-T11517
inservice
rserver RS-T1WBCT-WLS-10.102.161.174-T 11518
probe PR-T1WBCT-WLS-T11518
inservice

Hi,
This is becuse your server is listening on that port specificed under serverfarm.
ACE will send the request to the server on that port in the backend.

How the load balncer will forward the traffic to the client if the servers in the server faram with differennt port numbers?

This is how it works:
client ----> locadbalancer VIP (port 80) ----> server (11516)
In the above scenario, client makes a request toVIP on port 80 and ACE loadbalancer forward this traffic to server on port 11516. The reply goes back to the client in the same way and for client they only communicate on port 80.

Thanks Siva. I do not have any query if all the servers in the serverfarm are listening on the same application port
client -- ACE VIP (port 80)-- Server farm(all application servers S1,S2,S3 all listening on port 1124)
My question is how ACE will communicate with real servers if the servers in the same server farm listening on couple of ports.
Client ----------ACE VIP (On port 80) -------------------> Server Farm(Server 1 on 11516,Server 2 on 11517,Server 3 on 11518 )
Below is the config:
serverfarm host SF-T1WBCT-WLS-T11516
rserver RS-T1WBCT-WLS-10.102.161.173-T 11516
inservice
rserver RS-T1WBCT-WLS-10.102.161.173-T 11517
inservice
rserver RS-T1WBCT-WLS-10.102.161.173-T 11518
inservice

Thiyagu,
In the configuration you are making the ACE to forward the traffic on those ports.
rserver RS-T1... 11516
inservice
rserver RS-... 11517
inservice
rserver RS-T1... 11518

Siva
