Configuring PPP Properties for a Client-Specific Profile

To define PPP properties for a profile, include one or more of the following statements at the [edit access profile profile-name client client-name ppp] hierarchy level.


The properties defined in the profile take precedence over the values defined in the group profile.


When you configure a profile, you can configure either L2TP or PPP parameters, but not both at the same time.

The cell-overhead statement configures the session to use ATM-aware egress shaping on the IQ2 PIC.

bytes (in the encapsulation-overhead statement) configures the number of bytes used as overhead for class-of-service calculations.

ip-address (in the framed-ip-address statement) is the IPv4 prefix.

pool-id (in the framed-pool statement) is a configured address pool.

seconds (in the idle-timeout statement) is the number of seconds a user can remain idle before the session is terminated. By default, idle timeout is set to 0. You can configure this to be a value in the range from 0 through 4,294,967,295.

interface-id (in the interface-id statement) is the identifier for the interface representing an L2TP session configured at the [edit interfaces interface-name unit local-unit-number dial-options] hierarchy level.

keepalive seconds is the time period that must elapse before the Junos OS checks the status of the PPP session by sending an echo request to the peer. For each session, Junos OS sends a maximum of ten keepalives at 10-second intervals and the session is closed if there is no response. By default, the time to send a keepalive messages is set to 10 seconds. You can configure this to be a value in the range from 0 through 32,767 seconds.

keepalive-retries number-of-retries is the number of retry attempts for checking the keepalive status of a Point-to-Point (PPP) protocol session. Configuring a lower number of retries helps reduce the detection time for PPP client session failures or timeouts if you have configured a keepalive seconds value. By default, the number of retries is set to 10 times. You can configure this to be a value in the range from 3 through 32,767 times.

primary-dns (in the primary-dns statement) is an IPv4 address.

secondary-dns (in the secondary-dns statement) is an IPv4 address.

primary-wins (in the primary-wins statement) is an IPv4 address.

secondary-wins (in the secondary-wins statement) is an IPv4 address.
