Mô Tả

The Cisco® Catalyst® 3650 Series is the next generation of enterprise-class standalone and stackable access-layer switches that provide the foundation for full convergence between wired and wireless on a single platform. The 3650 Series is built on the advanced Cisco StackWise®-160, and takes advantage of the new Cisco Unified Access Data Plane (UADP) application-specific integrated circuit (ASIC). This switch can enable uniform wired-wireless policy enforcement, application visibility, flexibility, application optimization, and superior resiliency. The 3650 Series switches support full IEEE 802.3at Power over Ethernet Plus (PoE+), Cisco Universal Power over Ethernet (Cisco UPOE®) on the Cisco Catalyst 3650 Series multigigabit switches, and offer modular and field-replaceable redundant fans and power supplies. The 3650 Series switches also come in a 12-inch lower depth form factor so that you can deploy them in tight wiring closets in remote branches and offices where depth of the switch is a concern. In addition, the 3650 multigigabit switches support current and next-generation wireless speeds and standards (including 802.11ac Wave 2) on existing cabling infrastructure. The 3650 Series switches help increase wireless productivity and reduce TCO.

Cisco Catalyst Multigigabit Technology

Cisco Multigigabit Ethernet is a unique innovation to the new Cisco Catalyst Ethernet access switches. With the enormous growth of 802.11ac and new wireless applications, wireless devices are promoting the demand for more network bandwidth. This creates a need for a technology that supports speeds higher than 1 Gbps on all cabling infrastructure. Cisco multigigabit technology allows you to achieve bandwidth speeds from 1 Gbps through 10 Gbps over traditional Category 5e (Cat 5e) cabling or above. In addition, the multigigabit ports on select Cisco Catalyst switches support Cisco UPOE, which is increasingly important for next-generation workspaces and Internet of Things (IoT) ecosystems.

Cisco multigigabit technology offers significant benefits for a diverse range of speeds, cable types, and PoE power. The benefits can be grouped into three different areas:

   Multiple speeds: Cisco Catalyst Multigigabit Technology supports autonegotiation of multiple speeds on switch ports. The supported speeds are 100 Mbps, 1 Gbps, 2.5 Gbps, and 5 Gbps on Cat 5e cable and up to 10 Gbps over Cat 6a cabling

   Cable type: The technology supports a wide range of cable types, including Cat 5e, Cat 6, and Cat 6a or above

   PoE power: The technology supports PoE, PoE+, and Cisco UPOE for all the supported speeds and cable types

Cisco Catalyst 3650 Mini Switches

The Cisco Catalyst 3650 Series adds new mini switches to the existing 3650 family of switches. These switches are less than 12” deep and quieter than the existing 3650 switches, making them perfect to deploy in tight wiring cabinets, racks, or user spaces where depth of the switch is a concern. You can avoid replacing the cabinets or mounting the switch at an angle and as a result reduce downtime to the network. These switches enable the same uniform wired-wireless policy enforcement, application visibility, flexibility, application optimization, and superior resiliency as the existing 3650 switches. They come in 24- and 48-port 10M/100M/1000M switch SKUs (WS-C3650-24PDM and WS-C3650-48FQM) and support all the same features as the existing 3650 switches except that they come with fixed fans, fixed power supplies, and support for external RPS2300 for redundancy. These PoE switches support both PoE (IEEE 802.3af) and PoE+ (IEEE 802.3at standard), providing up to 30W of power for 12 ports for a total of 390W on the 24-port model and up to 30W of power for 24 ports for a total of 775W on the 48-port model. The 24-port switch has 2x1 Gigabit Ethernet SFP and 2x10 Gigabit Ethernet SFP+ uplinks; the 48-port switch has 4x10 Gigabit Ethernet SFP+ uplinks to support any high-bandwidth application. These switches support stacking and can stack with each other or the existing 3650 switches using the same Cisco StackWise-160 technology. The 3650 mini and 3650 use the same software and thus can be deployed and managed using the same policies, configuration, and so on as the existing 3650 switches. Some use cases for the 3650 mini are the following:

Small Offices and Branches

Many small branches and satellite offices where there are few employees do not have larger wiring closets because of space constraints. A typical office like this has smaller cabinets and would need a switch that can serve few employees, provide PoE support, can manage wired-wireless networks, and applies the same consistent policies as a bigger branch or office. Because of its less than 12” depth, lower noise, and support for 10G uplinks along with stacking, advanced security, and wired-wireless convergence, the 3650 mini is the perfect switch for this type of space.

Education

The 3650 mini switch extends access to labs, classrooms, and other training rooms from the central/floor distribution rooms, reducing cost of cabling and providing superior quality of service with enhanced security, wired-wireless convergence, and enterprise network features. Because of its shallow depth and lower noise, these switches are ideally suited for classrooms or confined areas.

Retail

A typical retail outlet needs to serve customers at multiple sales points, each with a POS machine, access points, phone, printer, video display with network, and some PoE powering. These retail outlets connect to the access router that connects them to the outside network and typically need switches that fit in shallow depth cabinets. Because of the 12” depth of these switches along with advanced security and networking features, they can help retailers efficiently utilize space and save on real estate cost.

Benefits

Converged Wired plus Wireless Access

The Cisco Catalyst 3650 Series is a standalone and stackable access switching platform that enables wired plus wireless services on a single Cisco IOS XE Software-based platform. With this, Cisco has pioneered a host of rich capabilities such as high availability based on stateful switchover (SSO) on stacking, granular QoS, security, and Flexible NetFlow (FNF) across wired and wireless in a seamless fashion. Also, the wired plus wireless features are bundled into a single Cisco IOS Software image, which reduces the number of software images that users have to qualify/certify before enabling them in their network. The single console port for command-line interface (CLI) management reduces the number of touch points to manage for wired plus wireless services, thereby reducing network complexity, simplifying network operations, and lowering the TCO to manage the infrastructure.

Converged wired plus wireless not only improves wireless bandwidth across the network but also the scale of wireless deployment. Each 48-port Cisco Catalyst 3650 provides 40 Gbps of wireless throughput (20 Gbps on the 24-port model). This wireless capacity increases with the number of members in the stack. This makes sure that the network can scale with current wireless bandwidth requirements, as dictated by IEEE 802.11n-based access points and with future wireless standards such as IEEE 802.11ac. Additionally, the Cisco Catalyst 3650 distributes the wireless controller functions to achieve better scalability. Each Cisco Catalyst 3650 switch/stack can operate as the wireless controller in two modes:

   Mobility agent (MA): This is the default mode in which the Cisco Catalyst 3650 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.

   Mobility controller (MC): In this mode, the Cisco Catalyst 3650 switch can perform all the mobility agent tasks in addition to mobility coordination, radio resource management (RRM), and Cisco CleanAir® coordination within a mobility subdomain. The mobility controller mode can be enabled on the switch CLI. IP Base license level is required when the Cisco Catalyst 3650 switch is acting as the mobility controller. A centrally located Cisco 5508 Wireless LAN Controller (WLC 5508), Cisco Wireless Services Module 2 (WiSM2) (when running AireOS Version 7.3), and Wireless LAN Controller 5760 can also perform this role for larger deployments.

With mobility agents located in the wiring closets providing 40 Gbps of wireless per switch (n x 40 Gbps for a stack of n switches) and mobility controllers managing some of the central wireless functions, the converged access-based wireless deployment provides best-in-class scalability for wireless and significantly improved wireless throughput.

Mobility Controller (MC) and Mobility Agent (MA)

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. This helps identify users and user traffic flows in order to identify potential attackers and take corrective action at the access layer before the attack penetrates further into the network. This is achieved using FNF, which monitors every single flow entering and exiting the switch stack for wired and wireless users. It also helps identify the top wired/wireless talkers and enforce appropriate bandwidth provisioning policies.

QoS

The 3650 switch has advanced wired plus wireless QoS capabilities. It uses the Cisco modular QoS command line interface (MQC). The switch manages wireless bandwidth using unprecedented hierarchical bandwidth management starting at the per-access-point level and drilling further down to per-radio, per-service set identification (SSID), and per-user levels. This helps manage and prioritize available bandwidth between various radios and various SSIDs (enterprise, guest, and so on) within each radio on a percentage basis. The switch is also capable of automatically allocating equal bandwidth among the connected users within a given SSID. This makes sure that all users within a given SSID get a fair share of the available bandwidth while being connected to the network. The UADP ASIC enables the hierarchical bandwidth management and fair sharing of bandwidth, thereby providing hardware-based QoS for optimized performance at line-rate traffic.

In addition to these capabilities, the switch is able to do class of service (CoS) or differentiated services code point (DSCP) based queuing, policing, shaping, and marking of wired plus wireless traffic. This enables users to create common policies that can be used across wired plus wireless traffic. The 3650 also supports downloadable policy names from the Cisco Identity Services Engine (ISE) when a user successfully authenticates to the network using the ISE.

Security

The Cisco Catalyst 3650 provides a rich set of security features for wired plus wireless users. Features such as IEEE 802.1x, Dynamic Host Configuration Protocol (DHCP) snooping, IP Source Guard and control plane protection, wireless intrusion prevention systems (WIPSs), and so on enable protection against unauthorized users and attackers. With a variety of wired plus wireless users connecting to the network, the switch supports session-aware networking, in which each device connected to the network is identified as one session, and unique access control lists (ACLs) and/or QoS policies can be defined and applied using the ISE for each of these sessions, providing better control on the devices connecting to the network.

Resiliency

Cisco StackWise-160 Technology

The Cisco Catalyst 3650 supports an optional stacking module that is based on the Cisco StackWise-160 technology. Cisco StackWise-160 technology is built on the highly successful industry-leading StackWise technology, which is a premium stacking architecture. StackWise-160 has a stack bandwidth of 160 Gbps. StackWise‑160 uses Cisco IOS Software SSO for providing resiliency within the stack. The stack behaves as a single switching unit that is managed by an “active” switch elected by the member switches. 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. A working stack can accept new members or delete old ones without service interruption. StackWise-160 creates a highly resilient single unified system of up to nine switches, providing simplified management using a single IP address, single Telnet session, single CLI, auto-version checking, auto-upgrading, auto-configuration, and more. StackWise-160 also enables local switching in Cisco Catalyst 3650 Series Switches. (See Figure 4.)

StackWise-160 Kit with Stack Adapters and Cables

Foundation for Open Network Environment

The heart of the Cisco Catalyst 3650 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.

Software Features and Services on Cisco Catalyst 3650 Series Switches

Software services supported on the Cisco Catalyst 3650 Series Switches can be classified into five broad categories:

   Ease of operations

   Advanced security features

   Resiliency

   Application visibility and control

   Audio Video Bridging (AVB)

Ease of Operations

The Cisco Catalyst 3650 helps reduce the operating costs through:

   Cisco Catalyst Smart Operations

   Easy-to-use deployment and control features

   Efficient switch operations

   Network management tools

Cisco Catalyst Smart Operations

Cisco Catalyst Smart Operations are a comprehensive set of capabilities that simplify LAN deployment, configuration, and troubleshooting. In addition to adaptive, always-on technologies such as StackWise-160, Cisco Catalyst Smart Operations enable zero-touch installation and replacement of switches, fast upgrade, and ease of troubleshooting with reduced operational cost. Cisco Catalyst Smart Operations are a set of features that includes Smart Install, Auto Smartports, Smart Configuration and Smart Troubleshooting to enhance operational excellence:

   Cisco Smart Install is a transparent plug-and-play technology to configure the Cisco IOS Software image and switch configuration without user intervention. Smart Install utilizes dynamic IP address allocation and the assistance of other switches to facilitate installation, providing transparent network plug and play.

   Cisco Auto Smartports provide automatic configuration as devices connect to the switch port, allowing auto‑detection and plug and play of the device onto the network.

   Cisco Smart Troubleshooting is an extensive array of debug diagnostic commands and system health checks within the switch, including Generic Online Diagnostics (GOLD) and Onboard Failure Logging (OBFL).

   Embedded Event Manager (EEM) is a powerful and flexible feature that provides real-time network event detection and onboard automation. Using EEM, customers can adapt the behavior of their network devices to align with their business needs. This feature requires the IP Base feature set.

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.

     Automatic QoS (AutoQoS) simplifies QoS configuration in voice over IP (VoIP) networks by issuing interface and global switch commands to detect Cisco IP phones, classify traffic, and help enable egress queue configuration.

     Autonegotiation on all ports automatically selects half- or full-duplex transmission mode to optimize bandwidth.

     Automatic media-dependent interface crossover (MDIX) automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight through) is installed.

   Simplified configuration and connectivity:

     Dynamic Trunking Protocol (DTP) facilitates dynamic trunk configuration across all switch ports.

     Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel groups or Gigabit EtherChannel groups to link to another switch, router, or server.

     Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with devices that conform to IEEE 802.3ad. This feature is similar to Cisco EtherChannel technology and PAgP.

     Unidirectional Link Detection Protocol (UDLD) and aggressive UDLD allow unidirectional links caused by incorrect fiber-optic wiring or port faults to be detected and disabled on fiber-optic interfaces.

     Cisco VLAN Trunking Protocol (VTP) Version 3 supports dynamic VLANs and dynamic trunk configuration across all switches.

   Efficient switch operation:

     Switching database manager (SDM) templates, VLAN template (specific to LAN Base license level), and advanced template allow the administrator to automatically optimize the ternary content-addressable memory (TCAM) allocation to the desired features based on deployment-specific requirements.

     Local proxy Address Resolution Protocol (ARP) works in conjunction with private VLAN edge to minimize broadcasts and maximize available bandwidth.

     Stacking master configuration management with Cisco StackWise-160 technology helps make sure that all switches are automatically upgraded when the master switch receives a new software version. Automatic software version checking and updating help ensure that all stack members have the same software version.

     Trivial File Transfer Protocol (TFTP) reduces the cost of administering software upgrades by downloading from a centralized location.

     Network Timing Protocol (NTP) provides an accurate and consistent timestamp to all intranet switches.

   Multicast:

     Optimized multicast for wired plus wireless: Cisco Catalyst 3650 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.

   Monitoring:

     Remote Switch Port Analyzer (RSPAN) allows administrators to remotely monitor ports in a Layer 2 switch network from any other switch in the same network.

     For enhanced traffic management, monitoring, and analysis, the Embedded Remote Monitoring (RMON) software agent supports four RMON groups (history, statistics, alarms, and events).

     Layer 2 traceroute eases troubleshooting by identifying the physical path that a packet takes from source to destination.

     Wireless RF management provides both real-time and historical information about RF interference affecting network performance across controllers using systemwide Cisco CleanAir technology integration.
