Description
This is an identification string between 1 and 63
characters (alpha and/or numeric) by which the LNS
service will be recognized by the system.
Multiple names are needed if multiple LNS services
will be used.
LNS services are configured in the source context.
Specifies how the system handles authentication: using
a protocol (such as CHAP, PAP, or MSCHAP), or
not requiring any authentication.
Specifies a context name for the system to use to
provide accounting functionality for a subscriber
session. This parameter is needed only if the system
is configured to support no authentication.
This defines the maximum number of sessions
supported by each tunnel facilitated by the LNS
service.
The number can be configured to any integer value
from 1 to 65535. The default is 65535.
This defines the maximum number of tunnels
supported by the LNS service.
The number can be configured to any integer value
from 1 to 32000. The default is 32000.
IP address or network prefix and mask:
The IP address of a specific peer LAC for which the
LNS service terminates L2TP tunnels. The IP address
must be expressed in dotted decimal notation. Multiple
peer LACs can be configured.
Alternately, to simplify configuration, a group of peer
LACs can be specified by entering a network prefix
and a mask.
Secret:
The shared secret used by the LNS to authenticate the
peer LAC. The secret can be from 1 to 256 alpha
and/or numeric characters and is case sensitive.
