Chassis

  • Support for MX-SPC3 in MX Series Virtual Chassis (MX240, MX480, and MX960 with MX-SPC3)—Starting in Junos OS Release 21.3R1, we support the MX-SPC3 service card in an MX Series Virtual Chassis setup for NAT, stateful firewall, and IDS features. However, you cannot configure aggregated multiservices (AMS) bundles with MX-SPC3 service cards on both the chassis.

    The maximum number of MX-SPC3 service cards that each chassis (in the Virtual Chassis setup) supports for different devices is as follow:

    • MX240: 2
    • MX480: 5
    • MX960: 7
