Main Features

The switch has the properties of a WIFI controller, thereby uniting networks of different types. When functioning in this role, this model of the switch can operate in two modes: Mobility Agent (being installed by default, this mode implements security settings for wireless access points and clients, and also supports client databases) and Mobility Controller (this mode helps manage radio resources and Cisco CleanAir technology, which distinguishes and eliminates possible radio interference). In addition, the WS-C3850-24XS-S is capable of servicing up to 50 access points and up to 2000 wireless clients.
High throughput
Cisco WS-C3850-24XS-S provides 454.55 Mbps of wireless network throughput. This figure increases in direct proportion to the number of switches in the stack. In this regard, the developers of this device have provided Cisco StackWise ports with a throughput of up to 480 Gbps, which forms a stack for 9 switches.
Working in a stack
The main advantages of the WS-C3850-24XS-S also include compatibility with Cisco StackPower technology, which combines all input power supplies within a stack of several switches, eliminating the need for a separate backup power supply.
Nutrition
The Cisco WS-C3850-24XS-S switch only supports AC 100-240V power.
Possibility of expansion
This model of the switch is equipped with a function for unified access to data (UADP), as well as special-purpose integrated circuits for direct solution of specific tasks. Also, the WS-C3850-24XS-S supports installation of redundant fans in case of heavy loads on the switch and additional power supplies.
IP Base Feature Pack
The IP Base feature set offers advanced intelligent services, including wireless controller management, shortest path to root (OSPF, BGP, and EIGRP), multicast routing problem solving (PIM), and traffic analysis with detailed packet inspection capability (Flexible NetFlow).
Advantages of the operating system
The licensed IOS operating system installed on this switch allows for timely system updates of software applications. Cisco WS-C3850-24XS-S has an extended list of functions that support the proper level of security of the provided connection.
Quality of Service
The Quality of Service package implements the following capabilities:
Bandwidth management that is performed based on a specific access point, selected radio frequency band, SSID, and a separate group of clients. Moreover, fair distribution of bandwidth between users within the SSID ensures a quality connection for each of them. Use of 802.1p CoS and DSCP based on the source and destination IP address, MAC address, or Layer 4 TCP/UDP port number. Shaped Round Robin (SRR) scheduling that intelligently manages queues. In addition, WTD helps prevent these queues from overflowing. The CIR rate matching function that ensures throughput with a minimum step of 8 kbps. Limiting is provided based on the source and destination IP address, source and destination MAC address, Layer 4 TCP UDP information, or any combination of these criteria. Eight outgoing queues per port.

Routing
Cisco Express Forwarding provides extremely high-performance IP routing:
static protocols, RIPv1 and RIPv2, RIPng, EIGRP;OSPF, EIGRP, BGPv4, IS-ISv4, OSPFv3, EIGRPv6;PBR (with IP Services);PIM for multicast routing (with IP Services);IPv6 support (with IP Services).

High availability
In addition to StackWise-480 and StackPower technologies, the Cisco WS-C3850-24XS-S supports high availability features:
Cross-Stack EtherChannel;FlexLink;IEEE 802.1s Multiple Spanning Tree Protocol;Per-VLAN Rapid Spanning Tree;automatic resumption of connection to the port due to network errors.
