Nexus 7000 M1-Series 48-Port Gigabit Ethernet Module


  • N7K-M148GS-11L
  • N7K-M148GT-11L

The Cisco Nexus 7000 M1 48-Port Modules with XL Option) are highly scalable modules designed for performance-driven, mission-critical Ethernet networks. The modules use the M1-XL forwarding engine, providing a throughput of up to 60 million packets per second (Mpps) and a large Forwarding Information Base (FIB), making them excellent for deployment at an Internet exchange point (IXP), a service provider, or a large enterprise. The 48-port modules are available in two versions: the fiber Gigabit Ethernet option using Small Form-Factor Pluggable (SFP) optics and the copper 10/100/1000 option with RJ-45 connectors.

The Cisco Nexus 7000 Series Switches comprise a modular data center-class product line designed for highly scalable 10 Gigabit Ethernet networks, with a fabric architecture that scales beyond 15 terabits per second (Tbps), and are designed to support high-density 40 and 100 Gigabit Ethernet deployments. Designed to meet the requirements of the most mission-critical network environments, these switches deliver continuous system operation and virtualized pervasive services. The Cisco Nexus 7000 Series is powered by the proven Cisco® NX-OS operating system, with enhanced features to deliver real-time system upgrades with exceptional manageability and serviceability. Its innovative unified fabric design is purpose built to support consolidation of IP, storage, and interprocess communication (IPC) networks on a single Ethernet fabric.

The Cisco Nexus 7000 M1-Series 48-Port Gigabit Ethernet Modules with XL Option have a number of key features that are designed to enable flexible deployment and support for the highest-performance environments, in which high density and a comprehensive feature set are required. With an optional Scalable Feature license, the modules can operate in enhanced XL mode, which enables utilization of the full forwarding table available on the forwarding engine, essential for large-scale deployments such as large enterprises or Internet peering environments. This larger FIB table can support multiple copies of the full Internet route table for use in Internet-facing deployments with Virtual Routing and Forwarding (VRF) and virtual device context (VDC) support. The capability to operate in either XL or non-XL mode makes these modules extremely flexible for many types of networking environments. The fiber version of the Cisco Nexus 7000 M1-Series 48-Port Gigabit Ethernet XL Module also supports a broad range of SFP optics, allowing deployment in various types of situations, from long-reach intersite deployments over single-mode fiber (SMF) to short- and medium-reach deployments over multimode fiber (MMF) for data center and campus environments. The Cisco Nexus 7000 M1-Series 48-Port Gigabit Ethernet Modules with XL Option provide 48 Gbps of local switching and are excellent for the access layer, where high density, high performance, and continuous system operation are crucial.

All Cisco Nexus 7000 M1-Series I/O modules contain integrated forwarding engines. The M1-XL forwarding engine on the 48-port modules is part of the Cisco Nexus 7000 M1-Series forwarding engines, incorporating larger FIB and access control list (ACL) tables. The module is fully compatible with, and offers feature consistency with, all existing M1 modules. Table 1 lists the performance specifications for the Cisco Nexus 7000 Series 48-Port Gigabit Ethernet Modules with XL Option operating in XL and non-XL modes.

The M1-XL forwarding engine delivers up to 60 Mpps of Layer 2 and Layer 3 IPv4 unicast forwarding or 30 Mpps of IPv6 unicast forwarding across all ports. The distributed architecture, with the forwarding engine integrated into each module, scales the forwarding performance of the chassis linearly by the number of I/O modules employed. The 18-slot chassis with 16 Cisco Nexus 7000 M1-Series 48-Port Gigabit Ethernet Modules with XL Option delivers up to 960 Mpps of IPv4 unicast forwarding. Multicast forwarding is built into the I/O module performing egress replication.

The M1-XL forwarding engine also delivers ACL filtering, marking, rate limiting, and NetFlow with no degradation of performance. Powerful ACL processing supports up to 64K entries per module in non-XL mode or 128K entries per module in XL mode, where entries can address Layer 2, 3, and 4 fields in addition to new Cisco metadata fields that employ security group tags (SGTs).

The Cisco Nexus 7000 M1-Series 48-Port Gigabit Ethernet Modules with XL Option offer exceptional security with integrated hardware support for Cisco TrustSec® technology. Security features include line-rate data confidentiality, data integrity, and ACL processing for SGTs. Data confidentiality and integrity conform to the IEEE MAC security standard (IEEE 802.1AE [MACsec]). All 48 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 feature removes dependencies on IP addresses, thus improving scalability and simplifying manageability.

The Cisco Nexus 7000 M1-Series 48-Port Gigabit Ethernet Modules with XL Option buffer data in virtual output queues (VOQs) before the data flows to the fabric. The data flow is controlled by a central arbiter on the supervisor module, using a credit-based buffer design. This architecture offers a lossless fabric that delivers quality of service (QoS) and fairness across all ports, even during congestion.
