avp-hiding
Syntax avp-hiding { never | sensitive | always }
no avp-hiding
Context config>router>l2tp>group>tunnel
Description
This command configures Attribute Value Pair (AVP) hiding. This capability can be used to avoid the
passing of sensitive data, such as user passwords, as cleartext in an AVP.
Note that it is recommended that sensitive information not be sent in clear text.
The no form of the command removes the parameter of the configuration and indicates that the value
on group level will be taken.
Default
no avp-hiding
Parameters avp-hiding — Specifies the method to be used for the authentication of the tunnel.
Values never — AVP hiding is not used.
sensitive — AVP hiding is used only for sensitive information (such as username/
password).
always — AVP hiding is always used.
