Load based throttling for AFT based linecards on MX10004 and MX10008

The load-based throttling feature, enabled by default, for AFT based linecard MX10K-LC9600 on MX10004 and MX10008, prevents saturation of line card processing capacity, reduces programming delays, and improves efficiency. The Packet Forwarding Engine (PFE) supports multi-threading and guides the Routing Engine (RE) to control packet management and load balancing. Ping based throttling is supported for non-AFT based line cards. This feature is supported for integrated and disaggregated border network gateway (BNG) modes, on the following interface types:

  • Gigabit Ethernet/Line Termination (GE/LT) managed concurrently on single AFT card interface.

  • Aggregated Ethernet/Remote Link Termination (AE/RLT) interface facilitates communication and control across various components in a network system on multiple AFT cards.

  • AE/RLT interface with AFT and non-AFT cards.

This feature supports the following commands under [edit] system services resource-monitor hierarchy:

  • The no-load-throttle command disables line card load-based throttling.

  • In disaggregated BNG mode, the no-usage-report statement disables PFCP (Packet Forwarding Control Protocol) usage reports.
