The IP netmask to be configured for the user when the user is a router to a
network. For DHCPv4 users, the attribute maps to DHCPv4 option [1] Subnet
mask and is mandatory if [8] Framed-IP-Address is also returned. For PPPoE
residential access, the attribute should be set to 255.255.255.255 (also the
default value if the attribute is omitted). For PPPoE business access, the
attribute maps to PPPoE IPCP option [144] Subnet-Mask only when the user
requests this option and if the node parameter configure subscriber-mgmt
ppp-policy <ppp-policy-name> ipcp-subnet-negotiation is set. Attribute is
omitted in accounting via configure subscriber-mgmt radius-accounting-
policy <name> include-radius-attribute no framed-ip-netmask.
Text that may be displayed to the user by a PPPoE client as a success, failure or
dialogue message. It is mapped to the message field from the PAP/CHAP
authentication replies to the user. Omitting this attribute results in standard
reply messages: login ok and login incorrect for PAP, CHAP authentication
success and CHAP authentication failure for CHAP. String length greater than
the defined Limits are accepted but truncated at this boundary.
