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 | IPv6 host mode
IPv6 over Ethernet

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.
