Guide
Attribute Meaning
Service Name An optional entry to set a specific service name to connect to
for the PPPoE session. If this is left blank the SM will accept
the first service option that comes back from the access
concentrator specified above, if any. This is limited to 32
characters.
Authentication
Type
None means that no PPPoE authentication is implemented
CHAP/PAP means that CHAP authentication is attempted
first, then PAP authentication. The same password is used for
both types.
User Name This is the CHAP/PAP user name that is used if CHAP/PAP
authentication is selected. If None is selected for
authentication then this field is unused. This is limited to 32
characters.
Password This is the CHAP/PAP password that is used if PAP
authentication is selected. If None is selected for
authentication then this field is unused. This is limited to 32
characters.
MTU
Use MTU Received from PPPoE Server causes the SM to
use the MRU of the PPPoE server received in LCP as the MTU
for the PPPoE link.
Use User Defined MTU allows the operator to specify an
MTU value to use to override any MTU that may be
determined in the LCP phase of PPPoE session setup. If this is
selected, the user is able to enter an MTU value up to 1492.
However, if the MTU determined in LCP negotiations is less
than this user-specified value, the SM will use the smaller
value as its MTU for the PPPoE link.
