Item Description
AVP Hidden
Specify whether to transfer AVP data in hidden mode.
With L2TP, some parameters are transferred as AVP data. You can
configure an LAC to transfer AVP data in hidden mode, namely,
encrypt AVP data before transmission, for higher security.
This configuration does not take effect on an LNS.
Flow Control
Specify whether to enable flow control for the L2TP tunnel.
The L2TP tunnel flow control function is for control of data packets
in transmission. The flow control function helps in buffering and
adjusting the received out-of-order data packets.
