Tunnel Flow-Control - H3C MSR810 Command Reference Manual

Usage guidelines
L2TP uses AVPs to transmit tunnel negotiation parameters, session negotiation parameters, and
user authentication information. This feature can hide sensitive AVP data, such as user passwords.
This feature encrypts AVP data with the key configured by using the tunnel password command
before transmission.
The tunnel avp-hidden command can be configured for L2TP groups in both LAC and LNS modes.
However, it does not take effect on L2TP groups in LNS mode.
For this command to take effect, you must enable tunnel authentication by using the tunnel
authentication command.
Examples
# Enable transferring AVP data in hidden mode.
<Sysname> system-view
[Sysname] l2tp-group 1 mode lac
[Sysname-l2tp1] tunnel avp-hidden

Usage guidelines
This feature adds sequence numbers to transmitted packets and uses them to reorder packets
arriving out of order and to detect lost packets.
This feature takes effect on both sent and r eceived L2TP data messages. The L2TP sessions
support this feature if either the LAC or LNS is enabled with this feature.
When the device acts as an LAC, a change in the flow control status on the LNS causes the same
change in the flow control status of L2TP sessions. When the device acts as an LNS, a change in the
flow control status on the LAC does not affect the flow control status of L2TP sessions.
Examples
# Enable L2TP session flow control.
<Sysname> system-view
[Sysname] l2tp-group 1 mode lac
[Sysname-l2tp1] tunnel flow-control
