A Nexus 9500 Series Switches line card can be categorized into two types, aggregation line cards and Application Centric Infrastructure (ACI) ready leaf line lards. Aggregation line cards provide high-density 10GE/40GE connectivity on a Nexus 9500 switch that runs in the classic NX-OS mode. ACI Ready Leaf Line Cards can operate in both the classis NX-OS mode and ACI mode.
All Nexus 9500 line cards consist of multiple NFEs for packets lookup and forwarding. Additionally, the ACI ready leaf line cards have a set of Application Leaf Engines (ALE). At its name indicates, ALE performs ACI leaf node functions when the Nexus 9500 switch is deployed as a leaf node in an ACI infrastructure. When the Nexus 9500 switch is operating in the classic NX-OS mode, the ALE on an ACI ready leaf line card mainly provides additional buffering and facilitates some networking functions, such as routing within a VxLAN overlay.
NFEs on a line card do L2 switching lookups and L3 host routing lookups. Line cards are equipped with various numbers of NFEs to support full line-rate forwarding performance for all IP packet sizes on all front panel ports.
In addition to the line-rate data plane performance, Nexus 9500 Series switch line cards also have a built-in dual-core CPU. This CPU is used to offload or speed up some control plane tasks such as programming the hardware table resources, collecting and sending line card counters and statistics, and offloading BFD protocol handling from the supervisors. This provides significant improvement to the system control plane performance.
The Cisco Nexus 9508 40 Gigabit Ethernet line card specification:
• 36-port 40 Gigabit Ethernet QSFP+ line card
• Designed for use in an aggregation switch role
• Cannot be upgraded to ACI mode
N9K-X9636PQ is an aggregation line card providing 36 40GE QSFP front panel ports. It has three network forwarding engines for packet forwarding, each supporting 12 40GE front panel ports and 12 internal ports to the fabric modules (clocked at 42 Gbps rate to accommodate the internal frame overhead). All of the 36 40GE front panel ports on N9K-X9636PQ support the 4x 10GE break-out mode to operate as 4 individual 10GE ports. This allows the line card to provide up to 144 10GE SFP+ ports.
This line card features a PHY-less design. This reduces the data transport latency on the port by 100ns, decreases the port power consumption and improves reliability due to fewer active components.
The trace lengths from each NFE to the 12 QSFP optics it supports are all under 7″, alleviating the need for re-timers. This further simplifies the line card design and reduces the number of active components.
