LTM I want to add 329 networks to be directed to a different pool than assigned to the VS. Could this be done by importing External file management?

Hi,

You can easily script a data group generation (even from Excel - use CONCATENATE() ) that contains the subnet as key and the pool name as data so you can more easily assign the pool - then just copy and paste the entries in TMSH.

create ltm data-group internal TEST-IP type ip

modify ltm data-group internal TEST-IP records add { 10.1.0.0/24 { data "STOREA-POOL" } }
modify ltm data-group internal TEST-IP records add { 10.2.0.0/24 { data "STOREB-POOL" } }

....

ltm data-group internal TEST-IP {
    records {
        10.1.0.0/24 {
            data STOREA-POOL
        }
        10.2.0.0/24 {
            data STOREB-POOL
        }
    }
    type ip
}
