Nimbostratus**** Mult-Pool Load Balancing based on Destination TCP port ****
If anyone can give me a bit of direction here I would be much obliged.
thx,
Ryan

- The_BhattmanYou can add some logging statements to see what is being applied
I.E.
log local0. "Complete connection: [IP::client_addr]:[TCP::client_port]<->LTM<->[IP::server_addr]:[TCP::server_port]"
I hope this helps

Ryan_Primavera_this is what I get back in the log when I add that in:
Oct 19 13:07:40 tmm tmm[1087]: 01220001:3: TCL error: Rule test_irule - Error: No serverside connection established (line 1) invoked from within "IP::server_addr"- The_BhattmanOops. I forgot that your event was client accepted
Try this:
log local0. "Client Connection: [IP::client_addr]:[TCP::local_port clientside]"
CB - Ryan_Primavera_Below basically is the functionality I am looking for. If there is a better way to skin the cat here I am all for it.
Example:
Client(REQ www.xyz.com:7300) => VirtualServer:0 (www.xyz.com:7300) => pool_7300 (poolmember:7300)
Client(REQ www.xyz.com:7320) => VirtualServer:0 (www.xyz.com:7320) => pool_7320 (poolmember:7320)
Client(REQ www.xyz.com:80) => VirtualServer:0 (www.xyz.com:80) => pool_any (poolmember:0) - Ryan_Primavera_
Try this:
log local0. "Client Connection: [IP::client_addr]:[TCP::local_port clientside]"

This what I am getting when using that. You can see it is getting the port. Now the reason why it won't pass to pool is beyond me.
Oct 19 13:16:42 tmm tmm[1087]: Rule test_irule : Client Connection: 192.168.0.100:7300 - The_BhattmanHow about you rewrite it in the following manner
when CLIENT_ACCEPTED { switch [TCP::local_port clientside] { "7300" { pool test_pool1 } "7310" { pool test_pool2 } "7320" { pool test_pool3 } "7330" { pool test_pool4 } "7340" { pool test_pool5 } "7350" { pool test_pool6 } default { pool test_pool_any } } }
I hope this helps

[TCP::local_port] in any clientside event (like CLIENT_ACCEPTED) is already run in the clientside context, so you don't need to to use the clientside keyword.
If CB's latest version isn't working, try adding logging to the switch cases to verify the request is matching the expected case. If that fails, then try a tcpdump or posting a sample of the VIP and pool config for one scenario that isn't working.
Also note that for unmatched destination ports, you're allowing unrestricted port access to the test_pool_any pool. This may or may not be a security concern for you.

Viv_RichardsAs per my requirement ,I have tried and it is working.
VS has been configured for all port (*) and for each local_port, traffic is destined to specific pool
=============================
when CLIENT_ACCEPTED {
switch [TCP::local_port clientside] {
"2181" {
pool pool_abcd_2181
log local0. "abcd port 2181 is:[TCP::local_port]"
}
"2182" {
pool pool_abcd_2182
log local0. "abcd port 2182 is:[TCP::local_port]"
}
"2183" {
pool pool_abcd_2183
log local0. "abcd port 2183 is:[TCP::local_port]"
}
"5051" {
pool pool_abcd_5051
log local0. "abcd port 5051 is:[TCP::local_port]"
}
"6051" {
pool pool_abcd_6051
log local0. "abcd port 6051 is:[TCP::local_port]"
}
"7051" {
pool pool_abcd_7051
log local0. "abcd port 7051 is:[TCP::local_port]"
}
"8051" {
pool pool_abcd_8051
log local0. "abcd port 8051 is:[TCP::local_port]"
}
"9051" {
pool pool_abcd_9051
log local0. "abcd port 9051 is:[TCP::local_port]"
}
"9092" {
pool pool_abcd_9092
log local0. "abcd port 9092 is:[TCP::local_port]"
}
"9093" {
pool pool_abcd_9093
log local0. "abcd port 9093 is:[TCP::local_port]"
}
"9094" {
pool pool_abcd_9094
log local0. "abcd port 9094 is:[TCP::local_port]"
}
"9095" {
pool pool_abcd_9095
log local0. "abcd port 9095 is:[TCP::local_port]"
}
default {
reject
log local0. "abcd port denied is:[TCP::local_port]"
}
}
}
==========================
Hope it will be helpful
