Cisco Catalyst 3850 48-Port Stackable Switch Feature And Benefit

Cisco Catalyst 3850 Series is the next generation of enterprise-class, stackable access-layer switches that provide full convergence between wired and wireless on one platform. Cisco’s new Unified Access Data Plane (UADP) application-specific microcircuit (ASIC) powers the switch and enables consistent wired-wireless policy enforcement, application visibility, flexibility, and application optimization. This convergence builds on the strength of the new and improved Cisco StackWise-480. Cisco Catalyst 3850 Series Switches support IEEE 802.3at Power over Ethernet Plus, modular and field-replaceable network modules, redundant fans, and power supplies.

Cisco StackWise-480 Technology

Cisco StackWise-480 technology is predicated on the highly successful industry-leading StackWise technology, which may be a premium stacking architecture. StackWise-480 has a stack bandwidth of 480 Gbps. StackWise-480 uses Cisco IOS Software SSO to provide resiliency within the stack. The stack behaves as one switching unit managed by an “active” switch chosen by the member switches. The active switch automatically chooses a backup switch within the stack. The active switch creates and updates all switching/routing / wireless information and constantly synchronizes that information with the standby switch. If the active switch fails, the standby switch takes over the role of the active switch and continues to keep the stack operational. 

Access points remain connected during a change from active to standby. A working stack can accept new members or remove old ones without interrupting service. StackWise-480 creates one highly resilient unified system of up to four switches, providing simplified management employing a single IP address, one Telnet session, one CLI, automatic version check, automatic update, automatic configuration, and more. StackWise-480 also enables local switching on Cisco Catalyst 3850 Series Switches.

Cisco StackPower Technology

Cisco Catalyst 3850 Series uses the Cisco StackPower technology present within the Cisco Catalyst 3850 Series. StackPower is an innovative power interconnect system that permits the facility supplies during a stack to be shared as a standard resource among all switches. Cisco StackPower unifies the individual power supplies installed within the switches and creates an influence pool, directing that power it’s needed. Up to four switches are often configured during a StackPower stack with the special connector on the rear of the switch using the StackPower cable, which is different from StackWise-480 cables.

StackPower is often deployed in power swap mode or in redundancy mode. In power distribution mode, power from all power supplies within the stack is aggregated and distributed among the switches within the stack. In redundant mode, when the entire battery power budget is calculated, the wattage of the most important power supply isn’t included. That power is held in reserve and wont to maintain power to connected switches and devices when an influence source fails, allowing the network to work without interruption. Upon failure of an influence supply, StackPower mode becomes Power Sharing.

StackPower allows customers to easily add a further power supply to any switch within the stack and supply power redundancy for any member of the stack or just add more power to the shared pool. StackPower eliminates the necessity for an external redundant power supply or the installation of dual power supplies across all members of the stack. StackPower is available at the LAN Base license level (or higher). For LAN Base, cables got to be purchased separately.

Converged wired and wireless access

The Cisco Switch Catalyst 3850 is the first stackable access switching platform to enable wired and wireless services on one Cisco IOS XE software-based platform. With this, Cisco has pioneered a number of rich capabilities like high availability supported stateful switching (SSO) in stacking, granular QoS, security, and versatile Netflow (FNF) over wired and wireless in a transparent manner. Additionally, wired and wireless features are bundled into one Cisco IOS Software image, reducing the number of software images that users must rate/certify before enabling them on their network. The single console port for command-line interface (CLI) management reduces the number of touchpoints to manage for wired and wireless services, reducing network complexity, simplifying network operations, and reducing the TCO to manage the infrastructure.


Cisco Catalyst 3850 provides an upscale set of security measures for wired and wireless users. Features such as IEEE 802.1x, Dynamic Host Configuration Protocol snooping, IP Source Guard and control plane protection, Wireless Intrusion Prevention Systems, etc., allow protection against attackers and non-users. authorized. With a spread of wired and wireless users connecting to the network, the switch supports session-aware networking, during which each device connected to the network is identified as a session, and access control lists and/or unique QoS policies. defined and applied using the ISE for each of these sessions, providing better control over the devices that connect to the network.

Application Visibility and control through flexible NetFlow

Cisco IOS FNF software is the next generation in flow visibility technology, enabling network infrastructure optimization, reducing operating costs, and improving capacity planning and security incident detection with increased flexibility and scalability. Cisco Catalyst 3850 provides optimized application visibility with FNF over wired and wireless. The switch is capable of 48,000 flow inputs on 48-port models and 24,000 flow inputs on 24-port models via wired and wireless. With UADP ASIC, the Cisco Catalyst 3850 offers next-generation flow technology with unprecedented flexibility and complete visibility that extends from Layer 2 (MAC and VLAN) indicators to Layer 4 (TCP / UDP) and so on through wired and wireless traffic. The Cisco Catalyst 3850 Switch is Medianet capable to supply visibility and troubleshooting capabilities in wired and wireless video traffic. Specific Medianet features are going to be enabled in future software updates.

The flow data collected by FNF can be exported to an external collector for analysis and reporting or the EEM can track it. The Cisco Switch Catalyst 3850 enables customizable event correlation and policy actions integrated with EEM, allowing switches to trigger custom event alarms or policy actions when the predefined condition is met. Without the need for an external device, customers can use the existing infrastructure for traffic monitoring, making traffic analysis economical even on a large IP network.

High-performance video over wireless technology integrates Cisco VideoStream technology to optimize the delivery of video applications over the WLAN. Wired and wireless IP telephony supports unified communications to enhance collaboration through messaging, presence, and conferencing and is compatible with all Cisco Unified Communications wireless IP phones for cost-effective, real-time voice service.
