Datasheet

Each line card contains a local CPU that is connected to the
chassis’ redundant Routing Engines over dedicated internal
gigabit control-plane links. This CPU manages the local line card
components, distributes forwarding table and other control plane
data from the Routing Engine to the local EX-PFE2 ASICs, and
returns line card status and CPU-directed control plane packets
to the Routing Engine. A second processor resident on each line
card aggregates flow-based statistics and analyzes sampled
packets without impacting control plane performance. Finally,
hot insertion and removal of all line cards is supported for online
maintenance and support.
