Option 125 is sent in response to option 124 that contains the
enterprise id you configured for.
Does the client provide option 124 in the DHCP message?
And you do not need the if statement for option 125.
If the client only sends option 60 then you want to use option 43.
In that case you want:
if substring (option vendor-class-identifier, 0, 5) = "test1" {
vendor-option-space TEST
option TEST.suboption = "Here is the string of this option";
}
