Question What is the default power-on sequence when line cards with Junos Trio chipsets are in the same chassis with other types of line cards? Answer If the set chassis network-services attribute is not configured, the following is the line card power-up rule: If the first PIC concentrator powered up is a DPC, then only DPCs within the box are allowed to power up
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

Answer The Gigabit Ethernet MPCs supports the following QoS functionality: - Port-based queuing Per-port shaping Eight queues per port 100 ms of delay buffer by default per port 200 ms of delay buffer configurable per port Ability to oversubscribe the delay buffer beyond 200 ms per port - Queue-level shaping and guaranteed rate Separate guaranteed and shaping rates Rate limit option to police a queue to act as a Low Latency Queue (LLQ) - Four WRED profiles per queue - Multiple queue priority levels - Strict High, High, Medium, and Low guaranteed priority levels Strict High and High are at the same hardware priority level Round robin at each guaranteed priority level - High and Low excess priority levels Queues perform WRR at the excess priority levels Strict priority scheduling at each excess priority level - Classification per VLAN MPLS EXP IPv6, IPv4 ToS Inner and outer tag 802.1p (and DEI7) MF classifiers per VLAN - Policers per VLAN Single rate, single-rate tricolor marking, two-rate tricolor marking, hierarchical policers Class-aware intelligent hierarchical policers Physical interface policers - Rewrites per VLAN MPLS EXP, IP DSCP/PREC Inner and outer tag 802.1p (and DEI7) Ingress DSCP rewrite For more information, see MX Series MS-MPC and MS-MIC Service Cards Data Sheet #vlan #GigabitEthernetMPC #FAQ
