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 1 and 10 Gigabit Ethernet access layer and 10 and 40 Gigabit Ethernet aggregation layer line card specification:
• 48-port 1 and 10 Gigabit Ethernet SFP+ with 4-port 40 Gigabit Ethernet QSFP+ line card
• Designed for use with Cisco Nexus 2000 Series Fabric Extenders and for mixed 10 and 40 Gigabit Ethernet aggregation
• Supports both direct-attach 10 Gigabit Ethernet copper cabling and optical transceivers
• Offers 4 QFSP+ ports that provide 40 Gigabit Ethernet server access, uplink, and downlink capacity
• Can be used in ACI leaf configurations

N9K-X9564PX is an ACI ready leaf line card. It provides 48 1GE SPF/10GE SPF+ ports and 4 40GE QSFP ports. Each of its 4 40GE ports supports the 4x10GE break-out mode to function as 4 individual 10GE ports. As a result, the line card can provide a maximum of 64 10GE ports. The port speed flexibility allows simple and cost-effective network access and aggregation design.
The key components on this line cards include two NFEs, two ALEs, and a line card CPU. The two NFEs provide the front panel ports. One NFE has 48 1/10G ports and the other has 4 40G ports. The two ALEs provide extended buffer space, additional packet handling and the option to use the line card in ACI mode.
To provide port type and speed flexibility, the front panel ports of this line card can operate at different speeds. Port speed mismatch is one of the primary reasons for port congestion and packet buffering. Consequently, this line card may need more buffer space than what its NFEs can provide. The two ALEs provide up to 40MB of additional buffering each. Since ALE is located between NFEs and fabric modules, it can buffer transit traffic between them. Locally switched traffic from a 10G port to a 1G port on the same NFE can also be redirected to the ALE sitting on its north bound interface to take advantage of the extended buffer space.
