  • IGMP and MLD snooping version configuration (ACX7100-32C, ACX7100-48L, ACX7509, PTX10004, PTX10008, and PTX10016)—Starting in Junos OS Evolved Release 23.4R1, you can configure the version of IGMP or MLD snooping queries for VLANs or bridge domains associated with Layer 2 (L2) multicast. This configuration ensures that end hosts or CPE devices that are not compliant with RFC 4541 and can’t normally respond to snooping queries of a later version are now able to process and respond to those snooping queries.

    To configure the IGMP or MLD snooping version, use the following CLI statements:

    • set protocols igmp-snooping version version
    • set protocols mld-snooping version version

    [See IGMP MLD Snooping Version Configuration.]

  • Recycle bandwidth management (ACX7024, ACX7100-32C, ACX7100-48L, ACX7348, and ACX7509)—Starting in Junos OS Evolved Release 23.4R1, we support the following two modes of recycle bandwidth management:.

    • Default mode, where all supported recycle applications share the recycle bandwidth in a best-effort manner.

    • Configuration mode, where you can reserve a guaranteed bandwidth for each configured recycle application.

    To configure bandwidth recycling using the configuration mode, use the following CLI statements:

    • set system packet-forwarding-options recycle-bandwidth-profiles profile-name
    • set system packet-forwarding-options recycle-bandwidth-profiles profile-name ingress-egress-mcast percentage srv6 percentage srv6-ext percentage
