Support for up to 256 Virtual Local Area Networks (VLANs) simultaneously
Port-based and 802.1Q tag-based VLANs
Management VLAN
Guest VLAN
Auto voice VLAN
Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS
QinQ VLAN
VLANs transparently cross a service provider network while isolating traffic among customers
Protocols for automatically propagating and configuring VLANs in a bridged domain
Head-of-Line (HOL) blocking
HOL blocking prevention
Jumbo frame
Frame sizes up to 9,216 supported
Loopback detection
Loopback detection provides protection against loops by transmitting loop protocol packets out of ports on which loop protection has been enabled. It operates independently of STP.
Automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight-through) is installed.
Security
ACLs
Drop or rate limit based on source and destination MAC, VLAN ID or IP address, protocol, port, Differentiated Services Code Point (DSCP)/IP precedence, Transmission Control Protocol (TCP)/ User Datagram Protocol (UDP) source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, Internet Group Management Protocol (IGMP) packets, TCP flag
Support up to 512 rules
Port security
Creates the ability to lock source MAC addresses to ports; limits the number of learned MAC addresses
IEEE 802.1X (authenticator role)
802.1X: Remote Authentication Dial-in User Service (RADIUS) authentication; guest VLAN;
Single-host, multiple-host, and multisession mode
RADIUS, TACACS+

MAC address filtering
Supported
Storm control
Broadcast, multicast, and unknown unicast
DoS protection
DOS attack prevention
STP Bridge Protocol Data Unit (BPDU) Guard
This security mechanism protects the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port.
Spanning Tree Loop Guard
This feature provides additional protection against Layer 2 forwarding loops (STP loops).
Secure Shell (SSH) Protocol
SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH v1 and v2 are supported.
Secure Sockets Layer (SSL)
SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch
QoS
Priority levels
8 hardware queues per port
Scheduling
Strict priority and Weighted Round-Robin (WRR) queue assignment based on DSCP and class of service (802.1p/CoS)
Class of service
Port-based; 802.1p VLAN priority-based; IPv4/v6 IP precedence, Type of Service (ToS), and DSCP-based; Differentiated Services (DiffServ); classification and re-marking ACLs, trusted QoS
Rate limiting
Ingress policer; egress shaping and rate control; per VLAN, per port, and flow-based
Congestion avoidance
A TCP congestion avoidance algorithm is required to reduce and prevent global TCP loss synchronization.
Multicast
Internet Group Management Protocol (IGMP) Versions 1, 2, and 3 Snooping
IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 256 multicast groups
IGMP querier
IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router
Support direct management with Cisco Business Dashboard and mobile app. Eliminates the need to set up a separate hardware or virtual machine for the Cisco Business Dashboard Probe on site.
Cisco Business mobile app
Mobile app for Cisco Business Switch and Wireless products. Helps to set up a local network in minutes and provide easy management at your fingertips.
Cisco Network Plug and Play (PnP) agent
The Cisco Network Plug and Play solution provides a simple, secure, unified, and integrated offering to ease new branch or campus device rollouts or for provisioning updates to an existing network. The solution provides a unified approach to provision Cisco routers, switches, and wireless devices with a zero touch deployment experience.
Supports Cisco PnP Connect
Web user interface
Built-in switch configuration utility for easy browser-based device configuration (HTTP/HTTPS). Supports configuration, system dashboard, system maintenance, and monitoring
Text-editable config files
Config files can be edited with a text editor and downloaded to another switch, facilitating easier mass deployment
Command-line interface
Scriptable CLI; a full CLI is supported. User privilege levels 1 and 15 are supported for the CLI
SNMP
Simple Management Network Protocol (SNMP) versions 1, 2c, and 3 with support for traps, and SNMP version 3 User-based Security Model (USM)
Embedded RMON software agent supports 4 RMON groups (history, statistics, alarms, and events) for enhanced traffic management, monitoring, and analysis
IPv4 and IPv6 dual stack
Coexistence of both protocol stacks to ease migration
Port mirroring
Traffic on a port or VLAN can be mirrored to another port for analysis with a network analyzer or RMON probe. Up to 8 source ports can be mirrored to one destination port. Four sessions are supported.
Firmware upgrade
Web browser upgrade (HTTP/HTTPS) and Trivial File Transfer Protocol (TFTP)
Dual images for resilient firmware upgrades
DHCP (Option 12, 66, 67, 82, 129, and 150)
DHCP options facilitate tighter control from a central point (DHCP server) to obtain IP address, auto-configuration (with configuration file download), DHCP relay, and hostname
Time synchronization
Simple Network Time Protocol (SNTP)
Login banner
Configurable multiple banners for web as well as CLI

The switch advertises itself using the Bonjour protocol
Link Layer Discovery Protocol (LLDP) (802.1ab) with LLDP-MED Extensions
LLDP allows the switch to advertise its identification, configuration, and capabilities to neighboring devices that store the data in a MIB. LLDP-MED is an enhancement to LLDP that adds the extensions needed for IP phones.
Cisco Discovery Protocol
The switch advertises itself using the Cisco Discovery Protocol. Displays brief information for connected Cisco network devices, IP phones, and wireless access points
Power efficiency
EEE compliance (802.3az)
