• The Catalyst 9000 series are designed with enterprise networks in mind. They are high-density, high-performance switches capable of supporting up to 480 Gbps of stacking bandwidth. The Catalyst 9300 series, for example, can support up to 48 ports of full Power over Ethernet Plus (PoE+) capability.

• The Catalyst 3850 series are stackable enterprise-level switches with 24 or 48 1Gbps Ethernet ports or 12 or 24 10Gbps Ethernet ports. These switches are unique in their support for wireless networking, allowing both wired and wireless network interfaces to be managed from a single point.

Cisco Nexus Switches

The Nexus series is Cisco's data center switch solution, offering both layer 2 and layer 3 top-of-rack and end-of-row switch models.

• The Nexus 9000 series switches are ideal for building a high-performance data center network. They offer a variety of port densities, speeds (from 1 to 100 Gigabit Ethernet), and form factors. For example, the Nexus 9508 switch offers eight slots in a compact 13-rack-unit form factor and supports up to 1152 10 Gigabit Ethernet ports.

• The Nexus 7000 series switches are also suitable for the data center environment, providing integrated resilience, advanced features such as FabricPath and FCoE (Fibre Channel over Ethernet), and up to 15 terabits per second (Tbps) capacity in a single chassis.

Cisco Integrated Services Routers

Cisco's Integrated Services Routers (ISRs) provide a multitude of services in one box, including routing, switching, wireless, and data center interconnect.

• The Cisco ISR 4000 series routers provide high-performance routing, crypto VPN for secure connections, and a multicore CPU architecture running modular Cisco IOS XE Software that dynamically adapts to the changing needs of branch environments.

• The Cisco ISR 1000 series offers small-to-medium-sized businesses and enterprise branches a high-performance router that includes an integrated network security solution with firewall and encryption, application visibility, control features, and optional integrated Wi-Fi and LTE.

Cisco Aggregation Services Routers

The Aggregation Services Routers (ASRs) are designed for high-end enterprise and service provider networks.

• The Cisco ASR 9000 series is designed for carrier-grade IP/MPLS networks and is capable of up to 96 Tbps total system capacity. It provides services such as MACsec encryption, advanced quality of service (QoS), and scalable network virtualization.

• The Cisco ASR 1000 series offers software and hardware redundancy, in-service software upgrades, and the ability to host third-party applications. It can also support up to 100 Gbps in a 2-rack-unit (2RU) form factor.

In conclusion, Cisco offers a broad range of switches and routers, each with its unique features and hardware specs, to cater to various networking requirements. From small businesses to large enterprises and service providers, Cisco's product lines offer robust and reliable solutions.
