extensiveKeepalive settings for the PPP sessions on the L2TP network server (LNS). LNS based PPP
sessions are supported only on service interfaces (si).
• Interval—Time in seconds between successive keepalive requests.
Keepalive aging timeout is calculated as a product of the interval and Down-count values.
If the keepalive aging timeout is greater than 180 seconds, the keepalive packets are handled
by the Routing Engine. If the aging timeout is less than or equal to 180 seconds, the packets
are handled by the Packet Forwarding Engine.
• Up-count—The number of keepalive packets a destination must receive to change a link’s
status from down to up.
• Down-count—The number of keepalive packets a destination must fail to receive before
the network takes down a link.

extensiveKeepalive statistics for the packets handled by the Routing Engine.
• LCP echo req Tx—LCP echo requests sent from the Routing Engine.
• LCP echo req Rx—LCP echo requests received at the Routing Engine.
• LCP echo rep Tx—LCP echo responses sent from the Routing Engine.
• LCP echo rep Rx—LCP echo responses received at the Routing Engine.
• LCP echo req timeout—Number of keepalive packets where the keepalive aging timer has
expired.
• LCP Rx echo req Magic Num Failures—LCP echo requests where the magic numbers shared
between the PPP peers during LCP negotiation did not match.
• LCP Rx echo repMagic Num Failures—LCP echo responses where the magic numbers shared
between the PPP peers during LCP negotiation did not match.
