Cisco Nexus 7000 48 Port 1/10 GbE, SFP/SFP+ F2-Series Module

The Cisco Nexus 7000 48-Port 1 and 10 Gigabit Ethernet F2-Series Module (referred to as the Cisco Nexus 7000 F2-Series Module) offers outstanding flexibility and wire-rate performance on each port. The next-generation Nexus 7000 platform comes to life with the F2-Series Modules, which deliver unmatched performance with Layer 2 and Layer 3 feature sets for the data center.

Features include:

• Performance: Line rate on all 48 ports with 720 Mpps (IPv4 or IPv6) and 480 Gbps of data throughput

• Scalability: Enables highest density 10GE system in the industry with up to 768 10 GE ports

• Feature-Rich: Comprehensive Layer 2 and Layer 3 forwarding functionality

• Nexus 2000 support: provides top-of-rack (ToR) flexibility and simplified operation for high-density 1/10GE deployments

• Cisco FabricPath support: Delivers highly reliable, flexible and scalable Layer 2 networks

• Fibre Channel over Ethernet (FCoE) support: Converges LAN and SAN over a single Ethernet network

• Flexibility: Dual-speed 1G/10G on a per-port basis [SFP and SFP+ options] for easy migration to 10GE

• Power-efficient: Less than 9W per port

• Deployment targets:

– Data center access, aggregation and core layer

– Gradual migration from 1 to 10GE for the access layer

Cisco Nexus 7000 9-Slot, 10-Slot and 18-Slot Chassis, 110 Gbps Fabric 2 Modules

The Cisco Nexus 7000 Series Fabric-2 Modules for the Cisco Nexus 7000 Series chassis are separate fabric modules that provide parallel fabric channels to each I/O and supervisor module slot. Up to five simultaneously active fabric modules work together delivering up to 550 Gbps per slot. Through the parallel forwarding architecture, a system capacity of more than 15 Tbps is achieved with the five fabric modules. The fabric module provides the central switching element for fully distributed forwarding on the I/O modules.

Figure 3. Cisco Nexus 7000 9-Slot, 10-Slot and 18-Slot Chassis, 110 Gbps Fabric 2 Modules

Features include:

• High availability and redundancy: The fabrics support multilevel redundancy, where all available fabrics are active, and provide redundancy for all other fabric modules. All I/O module slots receive a fair share of the total fabric bandwidth, helping to ensure lossless forwarding in the event of failover.

• Scalable fabric: The combined fabric modules deliver 10 channels per I/O module and five channels per supervisor module, for a scalable capacity of more than 15 Tbps for forwarding performance. This can be increased as a company's needs grow.

• Non-disruptive addition and removal of fabric modules: The switch capacity can scale with the addition of modules, with transparent upgrades for continuous operations.

• Arbitrated crossbar for unicast: Class-of-service-aware forwarding is delivered in a fully distributed forwarding system that allows future enhancements to Ethernet to support unified I/O.

• Virtual output queing (VOQ): In conjunction with the supervisor module, VOQ provides a quality-of-service (QoS) aware lossless fabric, avoiding the problems associated with head-of-line blocking.

• Multistage crossbar fabric: System forwarding performance is enhanced by a combination of local fabric switching between ports on the same module and centralized forwarding through the fabric for ports on different modules.

• Superframing and frame segmentation: Crossbar efficiency is optimized by the use of superframing and frame segmentation to provide deterministic latency and throughput. ID LED: Using the beacon feature, the administrator can clearly identify the chassis and fabric module.

Software Support

Cisco NX-OS Software Release 6.0 supports all the software features previously supported on the Cisco Nexus 7000 Series Switches up through Cisco NX-OS Software Release 5.2. Cisco NX-OS 6.0 is compatible using In-Service Software Upgrade (ISSU) with Releases 5.2 or higher. In addition, Cisco NX-OS 6.0 supports the new software features described in Table 4.
For more detailed information about features and ISSU, refer to the Cisco NX-OS 6.0 release notes (see "For More Information" at the end of this document).

Table 1. New Software Features in Cisco NX-OS Release 6.0

Software Features

Description

Border Gateway Protocol (BGP) best path as-path multipath-relax

When BGP multi-pathing is enabled, BGP load-balances user traffic within a single autonomous system (AS). The criteria are that all attributes must match (weight, AS P path, etc). However when a device is multi-homed to multiple AS(es), BGP cannot load balance traffic between the two AS(es) by default. In order to enable load-balancing of traffic among the multi-homed AS(es), the "bgp bestpath as-path multipath-relax" feature needs to be applied. The criteria required for this is that the AS-path length should be equal.

Simple Network Management Protocol (SNMP)

• Per-community SNMP object identifier (OID) access restriction: Provides fine granularity for role-based access control (RBAC) to control access at any OID level.
• Tunnel MIB: Addition of IP-TUNNEL-MIB.
