Specifications

RADIUS logical line identifier (MX Series)—Starting in Junos OS Release 13.3, service
providers can use a virtual port feature, known as the logical line ID (LLID), to maintain
a reliable and up-to-date customer database for those subscribers who move from
one physical line to another. The LLID, which is based on the subscriber's user name
and circuit ID, is mapped to the subscriber's physical line. When the subscriber moves
to a different physical line, the service provider database is updated to map the LLID
to the new physical line. Subscriber management supports the LLID feature for PPP
subscribers over PPPoE, PPPoA, and LAC.
[See RADIUS Logical Line Identifier (LLID) Overview.]
Configurable timers for DHCPv6 address-assignment pools (MX Series)—Starting
in Junos OS Release 13.3, subscriber management on MX Series routers supports
configurable timers for address-assignment pools that are used by a DHCPv6 local
server. In addition to the previously supported maximum-lease-time timer, you can
configure the valid-lifetime and preferred-lifetime timers to manage address leases
provided by address-assignment pools. You can also configure the renew (T1) and
rebind (T2) times that subscriber management uses to extend the lifetimes of addresses
obtained from an address-assignment pool.
[See DHCPv6 Lease Timers.]
DHCP statements and options (MX Series)—Starting in Junos OS Release 13.3, you
can use the following statements and options for DHCP subscriber management
support:
incoming-interface—New option that provides secondary identification match criteria
for the DHCP auto logout feature when there are duplicate clients.
delay-authentication—New statement that conserves managed resources on the
router by delaying subscriber authentication until the DHCP request processing
phase.
server-response-time—New statement that configures the timeframe during which
the router monitors DHCP server responsiveness. The router generates a system log
message when the DHCP server does not respond to relayed packets during the
specified time.
option hex-string—New option that enables the use of the hex-string option type for
user-defined DHCP attribute options that are added to client packets.
duplicate-clients-in-subnet—New statement that configures how the router
distinguishes between duplicate clients in the same subnet. This replaces the
duplicate-clients-on-interface statement, which is now obsolete.
[See client-discover-match, delay-authentication, server-response-time, option, and
duplicate-clients-in-subnet.]
Support for agent circuit identifier filtering in PPPoE subscriber session lockout
(M120, M320, and MX Series)—Starting in Junos OS Release 13.3, extend PPPoE
subscriber session lockout has been extended to support identification and filtering of
PPPoE subscriber sessions by either the agent circuit identifier (ACI) value or the unique
MAC source address on static or dynamic VLAN and static or dynamic VLAN demux
