Question Which product platforms use the Junos Trio chipset? Answer MX Series MPC line cards ̶ The MX Series MPC provides the connection between the customer’s Ethernet interfaces and the routing fabric of the MX Series chassis. The board features two Junos Trio chipsets. 16-port 10-Gigabit Ethernet MPC ̶ This MPC provides the connection between 10-Gigabit Ethernet LAN interfaces and the routing fabric of the MX Series chassis. It has four identical packet processing paths combined with a control plane. 100-Gigabit Ethernet MPC ̶ This MPC provides the connection between 100-Gigabit Ethernet LAN interfaces and the routing fabric of the MX Series chassis
Junos Continuity software is currently supported on the MX240, MX480, MX960, and MX2000 Series 3D Universal Edge Routers
To review performance, scalability, and power efficiency validation for the MX Series 3D routers with the Junos Trio chipset, see: EANTC testing validation This article provides answers to the most common questions about the Junos Trio chipset on MX Series routers used with Junos OS Release 10.1 and later
MX Series routers are available in a variety of configurations with robust features, including options that provide the level and granularity of the quality-of-service (QoS) support needed in your network
MPLS Configuration Supported Platforms DSCP Classifier Configuration Layer 3 VPNs and VPLSs using an LSI routing instance M320, M120, and MX Series Configured under class-of-service routing-instances on the egress PE router. Layer 3 VPNs using a virtual tunnel (VT) routing instance M320, M120, and MX Series Configured on the core-facing interface under class-of-service interfaces on the egress PE router. MPLS forwarding M320, M120, and MX Series (not supported on IQE and MX Series when ingress queuing is used) Configured on the ingress core facing interface under class-of-service interfaces on the P or egress PE router. VPLS using a VT routing instance Not supported MPLS forwarding when number of labels in the MPLS label stack is more than two Not supported For more information, see MX Series Interface Module Reference #MPLS-taggedpackets #FAQ #JuniperMXSeries #I-chip-basedDPC
Question What is the queuing buffer size on MX Series DPCs? Answer On port queuing DPCs, the delay buffer is 100 ms per port on egress
Answer The 16-port 10-Gigabit Ethernet MPC on MX Series routers has a total of four Packet Forwarding Engines per MPC
Question How can I define multiple port mirroring interfaces on a single chassis and select which traffic is mirrored to each interface on MX Series routers? Answer Junos OS supports multiple port mirror destinations in MX Series routers. All platforms support multiple source ports (interfaces that need to be mirrored). You can port-mirror traffic from a Layer 2 VPN on MX Series routers for PE routers. You can port-mirror the outgoing and incoming traffic of a given MX Series interface
Question What are the differences between the CoS traffic-manager options on the MX Series? Answer Use traffic-manager mode with the following options to configure CoS traffic manager mode of operation: egress-only—Enables CoS queuing and scheduling on the egress side for the PIC that houses the interface. This is the default mode for an Enhanced Queuing (EQ) DPC on MX Series routers. ingress-and-egress—Enables CoS queuing and scheduling on both the egress and ingress sides for the PIC. This is the default mode for IQ2 and IQ2E PICs on M Series and T Series routers
Question How many Layer 3 and Layer 2 policers are supported on Juniper Networks MX Series devices?
