New Features in Junos OS Release 10.4 for M Series, MX Series, and T Series Routers
Support for service session accounting statistics (MX Series routers)—You can now
capture accounting statistics for subscriber service sessions. Subscriber management
supports service session accounting based on service activation and deactivation, as
well as interim accounting. Time-based accounting is supported for all service sessions.
Time and volume-based accounting is supported for classic firewall filter and fast
update firewall filter service sessions only.
To provide volume service accounting, the well-known accounting counter
( junos-dyn-service-counter

family filter filter term term then]
The following VSAs (vendor ID 4874) are used for service accounting:

26-83 Acct-Service-Session
26-140 Service-Interim-Acct-Interval
[Subscriber Access]
Subscriber secure policy traffic mirroring supported for L2TP sessions on the LAC
(MX Series routers)—The L2TP access concentrator (LAC) implementation supports
RADIUS-initiated per-subscriber traffic mirroring. Both subscriber ingress traffic (from
the subscriber into the tunnel) and subscriber egress traffic (from the tunnel to the
subscriber) is mirrored at the (subscriber-facing) ingress interface on the LAC. The
ingress traffic is mirrored after PPPoE decapsulation and before L2TP encapsulation.
The egress traffic is mirrored after L2TP decapsulation. The mirrored packet includes
the complete HDLC frame sent to the LNS.
[Subscriber Access]
Support for static and dynamic CoS on L2TP LAC subscriber interfaces (M120, M320,
and MX Series routers)—Enables you to configure static and dynamic CoS for L2TP
access concentrator (LAC) tunnels that transport PPP subscribers at Layer 2 and Layer
3 of the network.
IP and L2TP headers are added to packets arriving at the LAC from a subscriber before
being tunneled to the L2TP network server (LNS). Classifiers and rewrite-rules enable
you to properly transfer the type-of-service (ToS) value or the 802.1p value from the
inner IP header to the outer IP header of the L2TP packet.
