iRule - Source Port persistence for a specific subnet else only source addr persistence

I am assuming that you are using the iRule in an UIE persistence profile that is attached to the VS.

In the iRule example that I have provided, persistence is based on "Client IP & Client Port" if the client IP matches the "datagroup_dg" and for client IP not matching the datagroup, persistence is based on just the "Client IP"

In the else statement use

persist uie [IP::client_addr]

 when CLIENT_ACCEPTED {
   if {[class match [IP::client_addr] equals "datagroup_dg"]} {
     set client_ip_port "[IP::client_addr]:[TCP::client_port]"
     persist uie $client_ip_port
   }
   else {
     persist uie [IP::client_addr]
   }
}

When you add information for the "value" field (seen in GUI) within the data group, you will be able to see the "data" keyword in the CLI within the datagroup like this:

ltm data-group internal CLASS-IP-DATA {
    records {
        10.10.10.0/24 {
            data abcd
        }
    }
    type ip
}

Datagroup format:

ltm data-group internal CLASS-IP-DATA {
    records {
        1.1.1.1/32 { }
    }
    type ip
}
