This command affects only L2TP data messages. The control messages are always processed on
the active MPU.
Specify traffic processing slots if a f eature requires that all traffic on a v irtual PPP interface be
processed on the same slot.
For high availability, you can specify one primary and one backup traffic processing slot by using
the service command and the service standby command, respectively.
To avoid processing slot switchover, specify the primary slot before specifying the backup slot. If you
specify the backup slot before specifying the primary slot, traffic is switched over to the primary slot
immediately after you specify the primary slot.
If you specify both primary and backup slots for an interface, traffic on that interface is processed as
