I am developing an ISG/Broadhop SME solution to offer some differentiated services for broadband customers.
The ISG/SME integration is working ok: As soon as the subscribers connect to the network they are redirected to the SME portal (PLAN portal), then the subscriber logs in and choose a service (increased BW for 1 hour). The service is applied correctly, but the subscriber is not kick out of the service when the time is up.
The SME is configured to apply L4 Redirection to the IP session as soon as the time is up. Looking at some debugs on the ISG (debug radius and debug aaa coa) I see that the CoA messages are received by the ISG but it shows an error and never apply the redirection.
Attach is a sample for the error.
What could be causing the error? If you need configs or SME screenshots, please let me know.
