How to use Session Limit

Session Limit feature allows Network Administrator to limit the number of sessions that a LAN client can use. This feature will prevent the router's resources from being occupied by a single host, especially who are downloading using P2P software. This article demonstrates how to set up Session Limit on Vigor Routers.

 1. Go to Bandwidth Management >> Session Limit, enable Session Limit and set a Default Max Session, this is the session limit that will apply to all the LAN clients.

5. (Optional) Network Administrator may use Session Limit with a schedule profile so that all sessions in Limitation List will be active only at a specific time or weekdays. Schedule profiles can be added from Application >> Schedule.
