Description

Specify the keepalive interval in a PPP dynamic profile.

Starting in Junos OS Release 15.1R5, you can configure the PPP keepalive interval for subscriber services in the range 1 second through 600 seconds. Subscriber PPP keepalives are handled by the Packet Forwarding Engine. If you configure a value greater than 600 seconds, the number is accepted by the CLI, but the Packet Forwarding Engine limits the interval to 600 seconds.

In earlier Junos OS releases, the range is from 1 second through 60 seconds. The Packet Forwarding Engine limits any higher configured value to an interval of 60 seconds.

PPP keepalives for nonsubscriber services are handled by the Routing Engine with an interval range from 1 second through 32,767 seconds.

Default

Sending of keepalives is enabled by default.

Options

interval seconds—The time in seconds between successive keepalive requests.

  • Range: 1 through 600 seconds for subscriber services

  • Range: 1 through 32767 seconds for nonsubscriber services

  • Default: 30 seconds for LNS-based PPP sessions. 10 seconds for all other PPP sessions.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 9.5.

Support at the [edit dynamic-profiles profile-name interfaces pp0 unit “$junos-interface-unit”] hierarchy level introduced in Junos OS Release 10.1.

Support at the [edit dynamic-profiles profile-name interfaces "$junos-interface-ifd-name" unit “$junos-interface-unit”] hierarchy level introduced in Junos OS Release 12.2.
