Tunnel Flow-Control - 3Com 3C13618 Command Reference Manual

3Com Router Command Reference Guide — V1.00
Parameter
None
Description
Using the tunnel avp-hidden command, you can enable hiding AV (attribute value)
pairs. Using the undo tunnel avp-hidden command, you can disable hiding AV pairs.
By default, hiding AV pairs is disabled.
This command can be used on both LAC and LNS, and is an optional configuration.
Upon configuration, the operation of hiding AV pairs makes sense only after tunnel
authentication and tunnel password are configured. When AV pairs are hidden, L2TP
hidden algorithm will be executed so that the username and password transmitted in
plain text during proxy authentication will be encrypted into AV pairs. Hiding AV pairs
in L2TP application is very useful when PAP or proxy authentication is used between
LAC and LNS.
In actual configuration, it is recommended to enable/disable hiding AV pairs on both
LAC and LNS at the same time.
Example
# Enable hiding AV pairs on L2TP group 1.
