Cisco Catalyst 3850 Series Switches

The Cisco

Catalyst

3850 Series is the next generation of enterprise-class stackable

Ethernet and Multigigabit Ethernet access and aggregation layer switches that provide

full convergence between wired and wireless on a single platform. Cisco’s new Unified

Access Data Plane (UADP) application-specific integrated circuit (ASIC) powers the

switch and enables uniform wired-wireless policy enforcement, application visibility,

flexibility and application optimization. This convergence is built on the resilience of

the new and improved Cisco StackWise-480 technology. The Cisco Catalyst 3850

Series Switches support full IEEE 802.3at Power over Ethernet Plus (PoE+), Cisco

Universal Power over Ethernet (Cisco UPOE), modular and field-replaceable network

modules, RJ45 and fiber-based downlink interfaces, and redundant fans and power

supplies. With speeds that reach 10Gbps, the Catalyst 3850 Multigigabit Ethernet

Switches support current and next-generation wireless speeds and standards

(including 802.11ac Wave 2) on existing cabling infrastructure.

● Mobility agent (MA): This is the default mode in which a Cisco Catalyst 3850 switch ships. In this mode the switch is capable of terminating the CAPWAP tunnels from the access points and providing wireless connectivity to wireless clients. Maintaining wireless client databases and configuring and enforcing security and QoS policies for wireless clients and access points can be enforced in this mode. No additional license on top of IP Base is required to operate in the mobility agent mode.

For more information on Converged Wired plus Wireless Access, refer to the Q&A document here: http://www.cisco.com/c/dam/en/us/products/collateral/switches/catalyst-3850-series-switches/cisco-catalyst-3850series-switches-faq.pdf. Distributed Intelligent Services Flexible NetFlow (FNF) Full visibility into the wired plus wireless traffic is achieved because of the access point Control and Provisioning of Wireless Access Points (CAPWAP) tunnel termination on the switch.
PAGE 8
The active switch automatically elects a standby switch within the stack. The active switch creates and updates all the switching/routing/wireless information and constantly synchronizes that information with the standby switch. If the active switch fails, the standby switch assumes the role of the active switch and continues to the keep the stack operational. Access points continue to remain connected during an active-to-standby switchover.

Foundation for Open Network Environment The heart of the Cisco Catalyst 3850 is the UADP ASIC with programmability for future features and intelligence with investment protection. The new ASIC provides the foundation for converged APIs across wired and wireless, Cisco Open Network Environment, software-defined networking (SDN) readiness and OnePK SDK through software updates over the product lifetime.

Easy-to-Use Deployment and Control Features ● User experience: ◦ IP service-level agreements (SLAs) enable customers to assure new business-critical IP applications, as well as IP services that utilize data, voice, and video, in an IP network. This feature requires the IP Services feature set. ◦ DHCP autoconfiguration of multiple switches through a boot server eases switch deployment.
PAGE 11
● Multicast: ◦ Optimized multicast for wired plus wireless: Cisco Catalyst 3850 offers greater multicast efficiency by receiving only one multicast stream and replicating it for all connected wired plus wireless devices connected to that switch. ◦ Internet Group Management Protocol (IGMP) v1, v2, v3 snooping for IPv4: multicast listener discovery (MLD) v1 and v2 snooping provides fast client joins and leaves of multicast streams and limits bandwidth-intensive video traffic to only the requestors.
PAGE 12
Advanced Security Features Cisco Catalyst 3850 Series Switches support advanced security features including but not limited to: ● Protection against attackers: ◦ Port security secures the access to an access or trunk port based on MAC address. It limits the number of learned MAC addresses to deny MAC address flooding. ◦ DHCP snooping prevents malicious users from spoofing a DHCP server and sending out bogus addresses.
PAGE 13
● Device access: ◦ Secure Shell (SSH) Protocol, Kerberos, and Simple Network Management Protocol Version 3 (SNMPv3) provide network security by encrypting administrator traffic during Telnet and SNMP sessions. SSH Protocol, Kerberos, and the cryptographic version of SNMPv3 require a special cryptographic software image because of U.S. export restrictions. ◦ TACACS+ and RADIUS authentication facilitates centralized control of the switch and restricts unauthorized users from altering the configuration.
PAGE 14
High-Performance IP Routing The Cisco Express Forwarding hardware routing architecture delivers extremely high-performance IP routing in the Cisco Catalyst 3850 Series Switches: ● IP unicast routing protocols (static, Routing Information Protocol Version 1 [RIPv1], and RIPv2, RIPng, Enhanced Interior Gateway Routing Protocol [EIGRP] stub) are supported for small-network routing applications with the IP Base feature set. Limited static routing with the LAN Base feature set.
PAGE 15
● Eight egress queues per port for wired traffic and four egress queues for wireless help enable differentiated management of different traffic types across the stack for wired traffic. Up to 2000 aggregate policers are available per switch.
PAGE 16
Backward compatibility with traditional centralized wireless deployment mode on the WLC 5508, WiSM2, and WLC 5760 helps ensure that customers can migrate to the Cisco Catalyst 3850-based converged access approach in phases, providing a continued controller for existing access points. This migration also provides investment protection on the existing wireless controller infrastructure.

Deploying the Cisco Catalyst 3850 in the Branch Access The new 12-port and 24-port SFP-based Cisco Catalyst 3850 models can also be used in the branch to aggregate traffic from smaller access switches through fiber links for more secure and EMI-sensitive deployments.

Power connectors ● Customers can provide power to a switch by using either the internal power or StackPower from another member in the power stack. The connectors are located at the back of the switch. ● Internal power supply connector: The internal power supply is an auto-ranging unit. The internal power supply supports input voltages between 100 and 240VAC. Use the supplied AC power cord to connect the AC power connector to an AC power outlet.

The 12-port and 24-port SFP based models can only be ordered with IP Base or IP Services licenses. Therefore, in order to stack with LAN Base models, they need to be configured in LAN Base mode from the CLI. Customers can transparently upgrade the software feature set in the Cisco Catalyst 3850 Series Switches through Cisco IOS Software CLI using the right to use (RTU)-based software upgrade process. Software activation enables the Cisco IOS Software feature sets.
