switch & swith -globe question

Hello,

 

 

I read many things in the forums and now I am more confused:)

 

I want to make my question clear, and waiting for your help as soon as possible. I need to give my irule cpu comparison report today..

 

 

Million thanks for your help in advance

 

 

---Firstly, I am doing all the following items with IF claues in prod enviroment without any problem but we want to make cpu utilization & and if it is possible we want to use switch clause.

 

 

* I have 4- 5 Ip ranges, and I need to decide which external group files will be chose.

 

* I have many external data group files. They all have many string values inside.

 

* I need to check $trx1 value, with these string values those inside the external datagroup files

 

* I could do this with IF statement but it comsumes so much CPU

 

* Thats why I am trying to using SWITCH clause instead of IF clause

 

 

 

Example:

 

 

If ip is in the x.x.x.x/24 ip range

 

If $trx1 in the A external datagroup file - do something

 

If $trx1 in the B external datagroup file- do something

 

If $trx1 in the C external datagroup file- do something

 

else- do something else

 

 

If ip is in the y.y.y.y/24 ip range

 

If $trx1 in the D external datagroup file - do something

 

If $trx1 in the E external datagroup file - do something

 

If $trx1 in the F external datagroup file - do something

 

else - do something else

 

 

else

 

do something - go to default pool
