Cisco 7000 M1, Refurbished network switch module

The Cisco Nexus® 7000 M1-Series 32-Port 10 Gigabit Ethernet Module with XL Option is a highly scalable high-performance module designed for mission-critical Ethernet networks. The module uses the M1-XL forwarding engine that features a larger Forwarding Information Base (FIB). The module also supports a wide range of Small Form Factor Pluggable Plus (SFP+) transceivers, including Twinax CX1, allowing deployment flexibility in various types of networking environments.

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 is designed to support high-density 40 and 100 Gigabit Ethernet deployments. Designed to meet the requirements of the most mission-critical network environments, it delivers continuous system operation and virtualized pervasive services. The Cisco Nexus 7000 Series is based on the proven Cisco® NX-OS Software 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.

Features and Benefits

The Cisco Nexus 7000 M1-Series 32-Port 10 Gigabit Ethernet Module with XL Option has a number of key features that are designed to enable flexible deployment and support for environments requiring the highest performance and a comprehensive feature set. With an optional Scalable Feature license, the module can operate in the enhanced XL mode, which enables use of the full forwarding table, essential for large-scale deployments such as 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 non-XL or XL mode makes this module extremely flexible for many types of networking environments, without requiring a hardware module change or upgrade, and delivers a lower total cost of ownership (TCO).

The 32-port module supports a broad range of transceiver modules, allowing deployment in various types of situations, including Twinax CX1 cable for in-rack or rack-to-rack links in the data center, long-reach intersite deployments over single-mode fiber (SMF), and short- and medium-reach deployments over multimode fiber (MMF) for data center and campus environments. The fabric interface on the 32-port module delivers 80 Gbps of bandwidth in each direction.

All Cisco Nexus 7000 I/O modules contain integrated forwarding engines. The M1-XL forwarding engine on the Cisco Nexus 7000 M1-Series 32-Port module is part of the Cisco Nexus 7000 M1-Series forwarding engines. The M1-XL forwarding engine is based on the M1 engine, incorporating larger FIB and access control list (ACL) tables. The module is fully compatible with, and offers feature consistency with, all existing M1 modules.

Each M1-XL forwarding engine delivers up to 60 million packets per second (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 sixteen Cisco Nexus 7000 M1-Series 32-Port 10 Gigabit Ethernet Modules with XL Option can deliver 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 32-Port 10 Gigabit Ethernet Module with XL Option offers exceptional security with integrated hardware support for Cisco TrustSec® technology, including line-rate data confidentiality, data integrity, and ACL processing for Security Group Tags (SGTs). Data confidentiality and integrity conform to the IEEE MAC security standard (IEEE 802.1AE [MACsec]). All 32 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, removing dependencies on IP addresses, thus improving scalability and simplifying manageability.

The Cisco Nexus 7000 M1-Series 32-port 10 Gigabit Ethernet Module with XL Option buffers 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.
