When the router is established as an LAC or LNS and is creating destinations, tunnels,

and sessions, you can manage them as follows:

NOTE: All the commands in this section apply to both the LAC and the LNS.

You can configure the router to generate a UDP data integrity checksum in data

packets sent to an L2TP peer. The router always uses UDP checksums during

transmission and reception of L2TP control packets. Generation of checksums is

disabled by default.

NOTE: This command does not affect the way the router checks the UDP data integrity

checksum in L2TP data packets that are received from an L2TP peer. The router

checks all non-zero received checksums and discards the packet if a data integrity

problem is detected.

You can specify the maximum time period, in the range 10–3600 seconds

Prevent the creation of new sessions, tunnels, and destinations.

Close and reopen all or selected destinations, tunnels, and sessions.

Configure drain timeout operations, which control the amount of time a

disconnected LAC tunnel waits before restarting after receiving a restart request.

Configure how many times the router retries a transmission if the initial attempt

is unsuccessful.
