Data SheetCisco Nexus 9300 ACI Fixed Spine SwitchesProduct OverviewIndustry shifts are redefining IT at all levels. On-premise IT consumption models are shifting to cloud-based services. IT as a Service (IaaS) is supplanted by applications as a service. Separate development and operations are moving toward integrated Development and Operations (DevOps). Device-centric management models are migrating to application-centric management.Business agility requires application agility, so IT teams need to provision applications in hours instead of months. Resources need to scale up (or down) in minutes, not hours. Traditional approaches take a siloed operational view, with no common operational model for the application, network, security, and cloud teams. A common operational model delivers application agility, simplified operations, assured performance, and scale.The Solution: An Application-Centric Approach to Managing Your InfrastructureCisco® Application Centric Infrastructure (ACI) is a holistic architecture with centralized automation and policy-based application profiles. The Cisco ACI fabric is designed from the foundation to support emerging industry demands while maintaining a migration path for architecture already in place. The fabric is designed to support the industry move to management automation, programmatic policy, and dynamic “workload-anywhere” models. The Cisco ACI fabric accomplishes this with a combination of hardware, policy-based control systems, and software closely coupled to provide advantages not possible in other models.The fabric consists of three major components: the Cisco Application Policy Infrastructure Controller (APIC), spine switches, and leaf switches. These three components handle both the application of network policy and the delivery of packets. Organizations can use the ACI-ready Cisco Nexus® 9000 Series Switches as spine or leaf switches to take full advantage of an automated, policy-based, systems management approach. The Cisco Nexus 9300 Series Switches include both spine and leaf switches. For detailed information, please refer here.Switch ModelsThe Cisco Nexus 9336PQ ACI Spine Switch is a 2-Rack-Unit (2RU) spine switch for Cisco ACI that supports2.88 Tbps of bandwidth and 2.3 billion packets per second (bpps) across 36 fixed 40 QSFP+ ports (Figure 1). Cisco Nexus 9300 platform leaf switches are Layer 2 and 3 nonblocking 10 and 40 Gigabit Ethernet switches with up to 2.56 Terabits per second (Tbps) of internal bandwidth.Figure 1.Cisco Nexus 9336PQ SwitchThe Cisco Nexus 9364C ACI Spine Switch is a 2-Rack-Unit (2RU) spine switch for Cisco ACI that supports 12.84 Tbps of bandwidth and 4.3 bpps across 64 fixed 40/100G QSFP28 ports and 2 fixed 1/10G SFP+ ports(Figure 2).

Configuring Module Pre-ProvisioningThis chapter describes how to configure pre-provisioning for offline interfaces or modules in the Cisco Nexus5000Series switch.This chapter includes the following sections:•Information About Module Pre-Provisioning,page1•Guidelines and Limitations,page2•Enabling Module Pre-Provisioning,page2•Removing Module Pre-Provisioning,page3•Verifying the Pre-Provisioned Configuration,page4•Configuration Examples for Pre-Provisioning,page5Information About Module Pre-ProvisioningThe pre-provisioning feature allows you to preconfigure interfaces before inserting or attaching a module toa Cisco Nexus5000Series switch.If a module goes offline,you can also use pre-provisioning to make changesto the interface configurations for the offline module.When a pre-provisioned module comes online,thepre-provisioning configurations are applied.If any configurations were not applied,a syslog is generated.The syslog lists the configurations that were not accepted.In some Virtual Port Channel(vPC)topologies,pre-provisioning is required for the configurationsynchronization feature.Pre-provisioning allows you to synchronize the configuration for an interface that isonline with one peer but offline with another peer.Supported HardwareThe pre-provisioning feature supports the following hardware:•N2K-C2148T Fabric Extender48x1G4x10G

5.0(2)N1(1),there are no configuration implications.When upgrading from a release that supportspre-provisioning to another release that supports the feature including InService Software Upgrades (ISSU),pre-provisioned configurations are retained across the upgrade.When downgrading from an image that supports pre-provisioning to an image that does not support pre-provisioning,you are prompted to remove pre-provisioning configurations.Guidelines and LimitationsPre-provisioning has the following configuration guidelines and limitations:•When a module comes online,commands that are not applied are listed in the syslog.•If a slot is pre-provisioned for module A and if you insert module B into the slot,module B does not come online.•There is no MIB support for pre-provisioned interfaces.•Cisco DCNM is not supported.Enabling Module Pre-ProvisioningYou can enable pre-provisioning on a module that is offline.Enter the provision model model command in module
