Subscriber Management and Services
- Dynamic
VLAN
(DVLAN single tag and dual tag) support for subscriber services scaling,
performance (ACX7100-48L) – Starting in Junos OS Evolved Release 23.4R1, we support
the following subscriber services scaling and performance features on the ACX7100-48L
devices:
- DHCP for IP-DEMUX lite and PPPoE subscribers (IPv4, IPv6, and dual stack) with CoS lawful intercept and filters.
- Protocol groups DHCPv6, L2TP, PPP, and PPPoE.
- Configuration of DVLAN (single and dual tag) with L2TP (LAC) DDoS policers for
broadband edge
(BBE)
protocols. We've enabled individual BBE protocol and
Distributed Denial
of Service
(DDoS)
protocol
group configurations . Only the aggregate DDoS protocol group
dhcpv4v6
is active. - Subscriber scale qualification with CoS for
L2TP
access controllers
(LAC)
subscriber interfaces for IPv4, IPv6, and dual stack.

- Support for new modular database (MDB) profiles to replace
old MDB profiles—Starting in Junos OS Evolved Release 23.4R1, new MDB profiles
replace older profiles for lean-edge, cloud metro, Carrier Ethernet, and Border Network
Gateways (BNGs). Additionally, here are a few enhancements provided with this feature :
-
The new MDB profiles configuration automatically restart PFEs.
- All MDB profiles now support IPv6 multicast source specific multicast (SSM)
- We define the
lean-edge
profile as the default profile instead of thebalanced
MDB profile - ACX7024 platform supports only the
lean-edge
andcloud-metro
profiles. -
We've removed the earlier restriction for LPM distribution. We've deprecated the LPM distribution command option
hw-db-profile lpm-distribution (1 | 2 | 200 | 3 | 4)
. -
You can use the MDB resource for either global routes or VRF routing tables and scale the resources to maximum per-profile capacity.

Hierarchical policer for subscriber services firewall (ACX7100-48L) —Starting in Junos OS Evolved Release 23.4R1, we support the following hierarchical policers on DHCP and Point-to-Point Protcol over Ethernet (PPPoE) access models:
- Single rate two-color marking policer
-
Single rate tri-color marking policer
-
Two rate tri-color marking policer
-
Hierarchical policer for DHCP and PPPoE
-
You can view the configuration by using the
show dynamic-profiles pppoe-client-policer-1-profile
command.[See Hierarchical Policer Overview and Example: Configuring a Hierarchical Policer for Subscriber Services Firewall (ACX7100-48L Devices).]
-
MAC source demultiplexing on control-plane interfaces (ACX7100-48L)—Starting in Junos OS Evolved Release 23.4R1, we support MAC-based source demultiplexing on control-plane interfaces on ACX7100-48L devices. The feature includes DHCP server dual (IPv4-only or IPv6-only) support for stack subscribers over a 1:N customer VLAN (C-VLAN). Use the DHCP server command
dhcpv6 [dynamic-profile dhcp-prof]
under the[edit system services dhcp-local-server]
hierarchy.[See dhcp-local-server (System Services) and dynamic-profile (Static Subscribers). ]
