Direct traffic to node or pool via irule on the basis of list of ports

in general you are right, there are some syntax issues with your code though, did you try it in the irule editor on the big-ip at all?

this works for me:

if { ( [TCP::local_port] == 15672 ) or ( [TCP::local_port] == 4369 ) or ( [TCP::local_port] == 25672 ) or ( [TCP::local_port] == 5672 ) or ( [TCP::local_port] == 61613 ) or ( [TCP::local_port] == 61614 ) or ( [TCP::local_port] == 1883 ) or ( [TCP::local_port] == 8834 ) } { 
    pool poola 
}  elseif { ( [TCP::local_port] == 22) } { 
    pool poolb 
}
`

still something with switch instead of if is probably cleaner and more readable

`switch [TCP::local_port] {
  "1883" -
  "4369" -
  "5672" -
  "8834" -
  "15672" -
  "25672" -
  "61613" -
  "61614" {
    pool poola
  }
  "22" {
    pool poolb
  }
  default {
     don't do anything...
  }
}
