Item Descri

tion
User Address
Specify the address pool for assigning IP addresses to users on the
peer end, or assign an IP address to a user directly.
If you have specified an ISP domain in PPP authentication
configuration, the address pools in the ISP domain are listed in the
User Address list. You can:
• Click Add to add an address pool, as shown in Figure 366. For
information about the configuration items, see Table 161.
• Select an address pool and click Modify to enter the address
pool modification page. For information about the
configuration items, see Table 161.
• Select an address pool and click Delete to delete the address
pool.
Assign Address
Forcibly
Specify whether to force the peer end to use the IP address
assigned by the local end. If you enable this function, the peer end
is not allowed to use its locally configured IP address.
Advanced
Configuration
Hello Interval
Specify the interval between sending hello packets.
To check the connectivity of a tunnel, the LAC and LNS regularly
send Hello packets to each other. Upon receipt of a Hello packet,
the LAC or LNS returns a response packet. If the LAC or LNS
receives no Hello response packet from the peer within a specific
period of time, it retransmits the Hello packet. If it receives no
response packet from the peer after transmitting the Hello packet
for three times, it considers that the L2TP tunnel is down and tries to
re-establish a tunnel with the peer.
The interval on the LAC end and that on the LNS end can be
different.
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.
