Cisco Nexus 7000 Next-Generation Hardware
The next-generation hardware on the Cisco Nexus 7000 platform includes the following.
• Cisco Nexus 7000 48 Port 1/10GbE, SFP/SFP+ Module (F2-Series)
Cisco Nexus 7000 9-slot chassis along with Fabric 2 module is supported on Cisco NX-OS Software Release 5.2 or later. Support for Fabric 2 modules 7010 and 7018 chassis, along with F2 module, is introduced in NX-OS Software Release 6.0.
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.
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.
• 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.
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
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.
Layer 2 Protocol support for the F2-Series 48-Port 1/10 GbE Module
Spanning Tree Protocol (STP), (Multiple Spanning Tree (MST) and RPVST+), virtual PortChannel (vPC), Link Aggregate Control Protocol (LACP) (up to 16 total links, including active and hot-standby), VLAN Trunk Protocol (VTP).
Layer 3 unicast support for the F2-Series 48-Port 1/10GbE module
IPv4 and IPv6, Web Cache Communication Protocol Version 2 (WCCPv2) Routing, Open Shortest Path First (OSPF) (v4 and v6), Enhanced Interior Gateway Routing Protocol (EIGRP), Intermediate System-to-Intermediate System (IS-IS, Border Gateway Protocol (BGP) [v 4 and v 6], Routing Information Protocol (RIP), Policy Based Routing (PBR), Hot Standby Router Protocol (HSRP) (v 4 and v 6), Gateway Load Balancing Protocol (GLBP), Virtual Router Redundancy Protocol (VRRP), Object Tracking, Bidirectional Forwarding Detection (BFD, 16-way Equal Cost Multipath (ECMP).
Multicast support for the F2-Series 48 Port 1/10GbE Module
Internet Group Management Protocol (IGMP) Snooping, IGMP, MLD, Protocol Independent Multicast (PIM) (Any Source Multicast [ASM]., Source Specific Multicast [SSM]), PIMv6, Multicast Source Discovery Protocol (MSDP).
Security support for the F2-Series 48-Port 1/10GbE Module
1A separate VDC is needed when deploying the N7K-F248XP-25 modules in a chassis that also contains other families of modules (i.e. N7K-M1xxx and N7K-F1xxx).The VDC feature is enabled by the N7K-ADV1K9 license.
1A separate VDC is NOT required when the chassis contains only N7K-F248XP-25 modules.
2Supported on NX-OS 5.2 or later releases. The rest are supported in NX-OS 6.0 or later releases.
Support for Cisco Nexus 2000 Series Fabric Extenders on F2 Module
The following Cisco Fabric Extenders are supported on the F2 module.
