I want to Send CoA-Requests to port other than 3799. Is there any method for doing so?
This is going to be done on JMX BNG
dynamic-request-port—(MX Series only) Starting in Junos OS Release 14.2R1, specify the port that the router monitors for dynamic (CoA) requests from the specified RADIUS servers. You can configure a port globally or for a specific access profile.
Thank you for the answer. That worked fine.
