  • Leading Catalyst switching platform for Unified Access deployments.
  • High capacity (848 gigabits) and density (240 full Power over Ethernet Plus ports).
  • 60 Watt Universal Power over Ethernet powers an unprecedented range of devices.
  • High availability with In-Service Software Upgrade and Stately Switchover.

1.2 Cisco Catalyst 3850 Series Switches

  • Best-in-class and feature-rich access platform with 480 Gbps stacking for gigabit desktop and 802.11ac wireless.
  • Converged wired and wireless access by extending wired features, resiliency, granular QoS, and scalability to wireless.
  • Distributed services across wired and wireless for security, policy, application visibility and control, and more.
  • Foundation for Cisco Open Network Environment enabled by a new ASIC with programmability and investment protection.

1.3 Cisco Catalyst 3650 Series Switches

  • Integrated wireless controller capability simplifies network architecture and operations.
  • Optional Cisco StackWise-160 technology provides scalability and resiliency.
  • Support for Cisco ONE Enterprise Networks Architecture with the UADP ASIC provides openness, programmability, and investment protection.

Cisco IOS XE software supports IPv4 and IPv6.
Modular QoS, Flexible NetFlow, and enhanced security features increase network flexibility, visibility, and controls.

1.4 Cisco Catalyst 2960-X Series Switches

  • Scalable fixed access switches with high resiliency for growth.
  • Smart, with intelligent networking and application-aware services for visibility and control.
  • Simple to operate, through embedded automation for software provisioning, quality of service (QoS), and plug-and-play.
  • Highly secure for users and applications with flexible authentication, Cisco TrustSec, and IPv6 first hop security.
  • Most environmentally friendly Catalyst switch to date.


1.5 Cisco Meraki MS Cloud-Managed Access Switches

  • Virtually stack switches to monitor and configure thousands of switch ports instantly over the web.
  • Integrated Layer 7 analysis delivers network-wide visibility into users, devices, and applications.
  • Provision sites and remotely troubleshoots networks without on-site IT Integrated tools such as Power over Ethernet (PoE), PoE Plus, QoS, Link Layer Discovery
  • Protocol (LLDP), and more ease voice and video deployments.
  • Integrated tools such as Power over Ethernet (PoE), PoE Plus, QoS, Link Layer Discovery Protocol (LLDP), and more ease voice and video deployments.


2. Campus LAN – Compact Switches
