A configuration variable comprised of nibbles i.e. 4 bits, such that
a client can supply a list of 0 to 8 selections. The least
significant nibble is the first value of the list, and the most
significant nibble is the last value. The value in each field
ranges from 0 to 15, however the first nibble with value 0 indicates
the end of the list. Repetition of values is not allowed.
Segregation of values is not allowed.
Valid Values are:
none - 0
pap - 1
chap - 2
eap - 3
Example valid encoding:
0x00000321
0x00000012
Not a valid encoding:
0x00000121
0x01002001
If authentication negotiation is not supported for this PPP interface,
then any attempt to explicitly set this object will result in a
notWritable error and it will be implicitly set to the DEFVAL on row
creation.
Setting this object to null will set
juniPppLinkConfigAuthenticatorVirtualRouter object to an empty string.
Setting this object along with the juniPppLinkConfigAuthentication object
will return an inconsistentValue error.
