Subscriber Management and Services

  • Access profile support per VLAN in a domain (MX Series devices and vMX)—Starting in Junos OS Release 21.3R1, you can configure subdomains under a domain map. In a subdomain, you can configure access profiles per VLAN or for a VLAN range. This enhancement gives you the flexibility to differentiate the users in a domain and to provide different services based on the users' profiles.

    [See map (Domain Map) and sub-domain.]

  • Enhancement to line cards for broadband edge (MX10003)—Starting in Junos OS Release 21.3R1, we've enhanced the line cards on the MX10003 to significantly improve the calls per second (CPS) for subscriber services.

    These are the enhancements to the line cards:

    • Four 2.4-GHz Rangley CPUs
    • Improved clock rate for the external DRAM

    [See MX10003 Routing and Control Board.]

  • Junos Multi-Access User Plane support for SGW-U and PGW-U co-location (MX204, MX240, MX480, MX960, and MX10003)—Starting in Junos OS Release 21.3R1, Junos Multi-Access User Plane provides a long-route implementation as a replacement for a filter-based implementation to steer traffic to the anchor Packet Forwarding Engine. The benefits are:

    • An external loopback connection to forward data when both the SGW-U and PGW-U are co-located in the same MX Series router is no longer necessary.
    • The firewall configuration to filter and route GTP packets to the anchor PFE is no longer necessary.

    You do not need to make any CLI configuration changes to take advantage of this enhancement. However:

    • You can remove the firewall filter for GTP packets.
    • To optimize throughput of 4G traffic, you can attach a specific 4G gateway type (PGW-U or SGW-U) to a specific anchor PFE by adding the new colocated-4g-pgw or colocated-4g-sgw option at the [edit services mobile-edge gateways saegw system anchor-pfes interface interface-name] hierarchy level.

    [See Junos Multi-Access User Plane Overview.]

  • CHAP password override in RADIUS Access-Request message (MX Series, vMX Series)—Starting in Junos OS Release 21.3R1, you can configure a CHAP password to override the existing password for authenticating any subscriber associated with the domain map. The override CHAP password replaces the CHAP challenge response from the PPPoE client when it attempts authentication.

    [See Changing the User Name and Password to Simplify Off-Chassis Provisioning.]

  • Support for RPF counters at Ethernet interface level (MX Series)—Starting in Junos OS Release 21.3R1, you can view RPF counters at the Ethernet interface level. To enable RPF counters at the Ethernet interface level, configure the rpf-stats statement at the [edit interfaces interface-name] hierarchy level. You can view and clear the RPF counters using the following commands, respectively:

    • show interfaces if-name extensive/detail

    • clear interfaces statistics if-name

    [See fields (for Interface Profiles), show interfaces statistics, and clear interfaces statistics.]

  • NAS-Port-ID format enhancement (MX Series devices and vMX)—In Junos OS Release 21.3R1, we've introduced a new NAS-Port-ID format for RADIUS server access request. The new NAS-Port-ID format is S-VLAN<concatenated 0’s>C-VLAN:S-VLAN-C-VLAN. For a C-VLAN, if the number of digits is less than four, precede it with zeros. For example, NAS-Port-ID for S-VLAN 72 and C-VLAN 82 is 720082:72-82.

    You can configure the fixed-size-inner-tag and fixed-size-outer-tag statements at the [edit access profile profile-name radius options nas-port-id-format concatenated-vlan-tags] hierarchy level.

    [See nas-port-id-format.]
