Cisco Catalyst 6816-X Chassis (Standard Tables) - Switch - Managed - 16 X 1 Gigabit SFP/ 10 Gigabit SFP+ - Desktop, Rack-mountable - Refurbished - C6816-X-LE-RF

• Platform scalability
  The platform supports up to 960 Gbps of switching capacity, which doubles up to 1.92 Tbps with VSS technology.
• Security
  Support for Cisco TrustSec to provide IEEE 802.1AE MACsec encryption and role-based ACL, CoPP to prevent DoS attacks, and Cisco ISE to safeguard and manage end-to-end security for the enterprise.
• Virtualization
  Comprehensive suite of virtualization features, including L2/L3 VPN, full MPLS, EVN, VRF-aware applications for NAT Netflow, GRE for v4/v6, L2 extensions with VPLS, and so on to segment different user groups and serve unique security/QoS policy requirements of each of these diverse user groups.
• Application visibility and control (AVC)
  Supports enhanced application monitoring such as Flexible and Sampled NetFlow and advanced priority queuing capabilities such as Hierarchical QoS.
• Smart operations
  The Cisco Catalyst 6840-X supports Cisco Catalyst Instant Access, which allows an Instant Access client to act as a remote line card of the Cisco Catalyst 6840-X, as well as Smart Install Director, which provides zero-touch deployment of access switches.
• High availability
  Two Cisco Catalyst 6840-X series Switches can be combined into a VSS. In addition to high availability VSS, provides ease of operation by providing a single point of management, eliminating the need for First Hop Routing Protocol (FHRP) and removing the reliance on Spanning Tree Protocol (STP) for link failure restoration.

The Cisco Catalyst 6840-X series switch is a 2RU fixed backbone switch in the Cisco Catalyst 6800 family. The 6840-X is based on the Cisco Catalyst 6800, with more than 3000 features and maturity of software code. The Cisco Catalyst 6840-X is the smallest Multiprotocol Label Switching (MPLS) aggregator or Instant Access controller in the Cisco 6800 Catalyst Family.
This 10G/40G-ready platform is ideal for those who want to introduce premium 10G services in small or midsize campus backbones. This unique platform offers 10G port density, full IPv4/IPv6 and MPLS/VPLS functionality with large table sizes (up to 256,000 FIB entries). With a full suite of L2/L3, virtualization, security, multicast, IPv6, application visibility, smart operations, and rich media services, the Cisco Catalyst 6840-X delivers unprecedented capabilities on day one. This platform also runs on the same architecture as the Cisco Catalyst 6500 Supervisor Engine 2T and therefore offers stability with proven operating system software.
The Cisco Catalyst 6840-X series chassis offers integrated resiliency by providing 1+1 power supply redundancy, single removable fan-tray with four redundant fans, and support for Virtual Switching System (VSS), thereby limiting network downtime, and makes sure of workforce productivity, customer satisfaction, and profitability.
