Up to 8 groups
Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation

VLAN

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

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+

Supports RADIUS and Terminal Access Controller Access Control System (TACACS) authentication; switch functions as a client

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

IPv6

IPv6 host mode
IPv6 over Ethernet

IPv6/IPv4 Dual Stack

Management

Cisco Business Dashboard

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)

Remote Monitoring (RMON)

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)

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
