Fixed In:

Opened: Mar 17, 2017
Severity: 3-Major


In the versions before 12.0, the order of parameters for "PEM::SESSIONS" rule was flexible. It was made strict because of the new validation infrastructure in 12.0. This breaks some existing iRules. The system will report a validation error such as: 01070151:3: Rule [/Common/test_irule] error: /Common/test_irule:2: error: ["invalid argument subscriber-type"][PEM::session create $ip subscriber-type e164 user-name $user imsi $imsi subscriber-id $callingstationid]


Configuration that was valid in earlier versions is not accepted in newer versions. This may result in the configuration failing to load during an upgrade and return an MCP validation error.


Some parameters, for example, subscriber-id come before the parameter user-name.


Change the order of the parameters.
