Cisco N7K-M108X2-12L Nexus 7000 Series 8-Port 10 Gigabit Ethernet Module with XL Option (requires X2)

Cisco Nexus 7000 Series 8-Port 10 Gigabit Ethernet Module with XL Option (X2 Optics) The Cisco Nexus 7000 8-Port 10 Gigabit Ethernet Module with XL Option is a cost-effective, highly scalable module designed for performance-driven, mission-critical Ethernet networks. The module uses two M1-XL forwarding engines, providing a throughput of up to 120 million packets per seconds (Mpps), eight nonoversubscribed 10 Gigabit Ethernet ports and a larger forwarding information base (FIB) table, making it ideal for deployment at an Internet Exchange Point (IXP), a service provider, or a large enterprise. The module supports a broad range of X2 optics, allowing deployment in various types of situations, from long-reach intersite over single-mode fiber to short and medium reaches over multimode fiber for data center and campus environments. The 8-port 10 Gigabit Ethernet module is supported by both the 18-slot and the 10-slot chassis (Cisco NX-OS 5.0 and later).

All Cisco Nexus 7000 Series I/O modules incorporate a dedicated forwarding engine, helping ensure that all data plane processing resides on the I/O modules. This high-availability architecture scales and isolates the control plane and data plane, delivering continuous operation even during upgrades. The forwarding engine also delivers ACL filtering, marking, rate limiting, and NetFlow without degrading performance.

The Cisco Nexus 7000 Series modules offer exceptional security, with integrated hardware support for Cisco TrustSec. Security features include line-rate data confidentiality, data integrity, and ACL processing for security group tags (SGTs). Data confidentiality and integrity conform to the IEEE MAC address security standard (IEEE 802.1AE [MACsec]). All ports on the module support the Advanced Encryption Standard (AES) cipher using a 128-bit key. New security ACLs are enhanced through hardware support for Cisco metadata headers capable of carrying SGTs. Security group ACLs (SGACLs) use SGT information to provide hardware-based enforcement of security policies. This approach removes dependencies on IP addresses, thus improving scalability and simplifying manageability.
