Maximum session limits on L2TP service interfaces

You can include the l2tp-maximum-session number statement at the [edit interfaces service-interface] hierarchy level to specify the maximum number of sessions that are allowed on an individual service interface (si) or aggregated service interface (asi). New session requests on an interface are accepted only when the session count is less than the maximum session limit. If the limit has been reached, subsequent requests are dropped and the LNS responds with a CDN message (Result Code 2, Error Code 4). If a pool of interfaces is configured, interfaces at the maximum limit are ignored in favor of an interface in the pool that has a lower session count. For an asi interface, the configuration applies to all member interfaces; you cannot configure the limit for individual member interfaces.
